Switch-Mode Battery Charger ICs

Switch-Mode 1-Cell Li+ Chargers

The MAX1925/MAX1926 single-cell lithium-ion (Li+)
switch-mode battery chargers use an external PMOS
pass element step-down configuration. Charge current
is programmable, and an external capacitor sets the
maximum charge time.

Additional features include automatic input power
detection (ACON output), logic-controlled enable, and
temperature monitoring with an external thermistor. The
MAX1925 disables charging for inputs greater than
6.1V, while the MAX1926 charges for inputs between
4.25V and 12V.

The MAX1925/MAX1926 feature two precondition levels
to restore near-dead cells. The devices source 4mA to
a cell that is below 2V while sourcing C/10 to a cell
between 2V and 3V. Full charge current is then applied
above 3V. A CHG output drives an LED to indicate
charging (LED on) and fault conditions (LED blinking).
The MAX1925/MAX1926 are available in a 12-pin
4mm * 4mm thin QFN package and are specified over
the extended temperature range (-40°C to +85°C). An
evaluation kit is available to speed design.

charging lithium-ion (Li+) battery packs. It provides a
regulated charging current of up to 4A without getting
hot, and a regulated voltage with only ±0.75% total
error at the battery terminals. It uses low-cost, 1% resistors
to set the output voltage, and a low-cost N-channel
MOSFET as the power switch.

The MAX745 regulates the voltage set point and charging
current using two loops that work together to transition
smoothly between voltage and current regulation.
The per-cell battery voltage regulation limit is set
between 4V and 4.4V using standard 1% resistors, and
then the number of cells is set from 1 to 4 by pin-strapping.
Total output voltage error is less than ±0.75%.
For a similar device with an SMBus™ microcontroller
interface and the ability to charge NiCd and NiMH cells,
refer to the MAX1647 and MAX1648. For a low-cost Li+
charger using a linear-regulator control scheme, refer

Linear Battery-Charger ICs

NiCd/NiMH Battery
Fast-Charge Controllers

The MAX712/MAX713 fast-charge Nickel Metal Hydride
(NiMH) and Nickel Cadmium (NiCd) batteries from a DC
source at least 1.5V higher than the maximum battery
voltage. 1 to 16 series cells can be charged at rates up
to 4C. A voltage-slope detecting analog-to-digital converter,
timer, and temperature window comparator determine
charge completion. The MAX712/MAX713 are powered
by the DC source via an on-board +5V shunt regulator.
They draw a maximum of 5µA from the battery when not
charging. A low-side current-sense resistor allows the
battery charge current to be regulated while still
supplying power to the battery’s load.
The MAX712 terminates fast charge by detecting zero
voltage slope, while the MAX713 uses a negative
voltage-slope detection scheme. Both parts come in 16-
pin DIP and SO packages. An external power PNP transistor,
blocking diode, three resistors, and three
capacitors are the only required external components.
The evaluation kit is available: Order the MAX712EVKITDIP

Cost-Saving Multichemistry
Battery-Charger System

The MAX846A is a cost-saving multichemistry batterycharger
system that comes in a space-saving 16-pin
QSOP. This integrated system allows different battery
chemistries (Li-Ion, NiMH or NiCd cells) to be charged
using one circuit.

In its simplest application, the MAX846A is a standalone,
current-limited float voltage source that charges
Li-Ion cells. It can also be paired up with a low-cost
microcontroller (µC) to build a universal charger capable
of charging Li-Ion, NiMH, and NiCd cells.
An internal 0.5%-accurate reference allows safe charging
of Li-Ion cells that require tight voltage accuracy.
The voltage- and current-regulation loops used to control
a low-cost external PNP transistor (or P-channel
MOSFET) are independent of each other, allowing more
flexibility in the charging algorithms.
The MAX846A has a built-in 1%, 3.3V, 20mA linear regulator
capable of powering the µC and providing a reference
for the µC’s analog-to-digital converters. An
on-board reset notifies the controller upon any unexpected
loss of power. The µC can be inexpensive, since
its only functions are to monitor the voltage and current
and to change the charging algorithms.

Feature
- Multichemistry Charger System (Li-Ion, NiMH, NiCd)
- Independent Voltage and Current Loops
- ±0.5% Internal Reference for Li-Ion Cells
- Lowers Cost:
—Stands Alone or Uses Low-Cost µC

9 Bit Magnetic Rotary Encoder ICs

AM512B
Angular magnetic encoder IC

The AM512B is a compact solution for angular
position sensing. The IC senses the angular
position of a permanent magnet placed above
the chip. The permanent magnet must be
diametrically polarized and of cylindrical shape.
The AM512B uses Hall sensor technology to
detect the magnetic flux density distribution at
the surface of the silicon. Hall sensors are
placed in a circular array around the center of
the IC and deliver a voltage representation of
the magnetic field distribution.

The sine and cosine voltage outputs from the
sensor array vary with magnet position. The
sine and cosine signals are then converted to
absolute angle position with a fast nine bit flash
interpolator.

The absolute angle position value from the
interpolator is output either through a parallel
binary interface, a serial SSI interface or a linear
voltage output. The relative changes of the
angle position are also output as incremental
A QUAD B encoder signals. The resolution of
incremental output is 512 counts per turn.

Features
- Contactless angular position encoding over 360°
- Ideal for harsh environments due to magnetic
sensing
- Complete system-on-chip solution
- 9 bit absolute encoder
- Output options:
- Incremental
- Parallel
- Serial SSI
- Analogue linear
- Factory optimized linearity
- High rotational speed up to 30,000 rpm
- 5 V power supply
- Low power consumption. 20 mA typical.
- Extended operating temperature range
(-40 °C to +125 °C)

AS5130
8 Bit Programmable Magnetic Rotary Encoder
with Motion Detection & Multiturn

The AS5130 is a contactless magnetic rotary encoder
for accurate angular measurement over a full turn of
360º. It is a system-on-chip, combining integrated Hall
elements, analog front end and digital signal processing
in a single device. The angle can be measured using
only a simple two-pole magnet rotating over the center
of the chip. The magnet may be placed above or below
the IC. The absolute angle measurement provides
instant indication of the magnet’s angular position with a
resolution of 8 bit = 256 positions per revolution. This
digital data is available as a serial bit stream and as a
PWM signal. The AS5130 can be operated in pulsed
mode (Vsupply=off), which reduces the average power
consumption significantly. During Vsupply=off, the
measured angle can be stored using an internal storage
register supplied by a low power voltage line. This mode
achieves very low power consumption during polling of
the rotary position of the magnet. If the position of the
magnet changes, then the motion detection feature
wakes up an external system. The device is capable of
counting the amount of magnet revolutions. The multi
turn counter value is stored in a register and can be read
in addition to the angle information. Furthermore, any
arbitrary position can be set as zero-position. The
system is tolerant to misalignment, air gap variations,
temperature variations and external magnetic fields and
high reliability due to non-contact sensing.

Features
- 360º contactless angular position encoding
- Two digital 8-bit absolute outputs:
- Serial interface
- Pulse width modulated (PWM) output
- User programmable zero position
- High speed: up to 30000 rpm
- Failure detection mode for magnet placement monitoring
and loss of power supply
- Wide temperature range: - 40ºC to +125ºC
- Multi Turn counter / Movement detection
- Small Pb-free package: SSOP-16 (5.3mm x 6.2mm)
- Automotive qualified to AEC-Q100, grade 1

AM256
Angular magnetic encoder IC
The AM256 is a compact solution for angular
position sensing. The IC senses the angular
position of a permanent magnet placed above the
chip. The permanent magnet must be
diametrically polarized and of cylindrical shape.
The AM256 uses Hall sensor technology to detect
the magnetic flux density distribution at the
surface of the silicon. Hall sensors are placed in a
circular array around the center of the IC and
deliver a voltage representation of the magnetic
field distribution.

The sine and cosine voltage outputs from the
sensor array vary with magnet position. The sine
and cosine signals are then converted to absolute
angle position with a fast eight bit flash
interpolator.

The absolute angle position value from the
interpolator is output through a parallel binary
interface or a serial SSI interface. The relative
changes of the angle position are output through
incremental A QUAD B encoder signals. The
resolution of incremental output is selectable
between 128 and 256 counts per turn with an
external pin

Features:
- Contactless angular position encoding over 360°
- Ideal for harsh environments due to magnetic
sensing
- Complete system-on-chip solution
- 8 bit absolute encoder
- Output options:
- Incremental
- Parallel
- Serial SSI
- Analogue sinusoidal
- Factory optimized linearity
- High rotational speed up to 60,000 rpm
- 5 V power supply
- Low power consumption. 13 mA typical.
- Extended operating temperature range
(-40 °C to +125 °C)
- SMD package SSOP28
- RoHS compliant (lead free)

ISL29001

Block Diagram

The ISL29001 is an integrated ambient light sensor with
ADC and I2C interface. With a spectral sensitivity curve
matched to that of the human eye, the ISL29001 provides
15-bit effective resolution while rejecting 50Hz and 60Hz
flicker caused by artificial light sources.

In normal operation, the ISL29001 consumes less than
300µA of supply current. A software power-down mode
controlled via the I2C interface disables all but the I2C
interface. A power-down pin is also provided, which reduces
power consumption to less than 1µA.

The ISL29001 includes an internal oscillator, which provides
100ms automatic integration periods, or can be externally
timed by I2C commands. Both the internal timing and the
illuminance resolution can be adjusted with an external
resistor.

Designed to operate on supplies from 2.5V to 3.3V, the
ISL29001 is specified for operation over the -40°C to +85°C
ambient temperature range. It is packaged in a clear 6 Ld
ODFN package.

TSL2550
AMBIENT LIGHT SENSOR
WITH SMBus INTERFACE

Description
The TSL2550 is a digital light sensor with a two-wire, SMBus
serial interface. It combines two photodiodes and a companding
analog-to-digital converter (ADC) on a single CMOS integrated
circuit to provide light measurements over an effective 12-bit
dynamic range.

The TSL2550 is designed for use with broad wavelength light
sources. One of the photodiodes (Channel 0) is sensitive to
visible and infrared light, while the second photodiode
(Channel 1) is sensitive primarily to infrared light. An integrating
ADC converts the photodiode currents to Channel 0 and
Channel 1 digital outputs. Channel 1 digital output is used to
compensate for the effect of the infrared component of ambient
light on Channel 0 digital output. The ADC digital outputs of the
two channels are used to obtain a value that approximates the
human eye response in the commonly used unit of Lux.

Feature
_ Converts Light Intensity to Digital Signal
_ Infrared Compensation to Approximate
Human Eye Response
_ Companding A/D for Wide Dynamic Range
_ Rejects 50 Hz/60 Hz Lighting Ripple
_ Two-Wire SMBus Serial Interface
_ Single Supply Operation (2.7 V to 5.5 V)
_ Low Active Power (1 mW typ)
