AAT3620: Single Cell Li+ Switch Mode Battery Charger

Applications

Description

The BatteryManager™ AAT3620 is an ideal solution for charging

high-capacity Li+ batteries. The AAT3620 can supply up to 2.0 A

charging current with minimal thermal impact to mobile systems

with features such as color display, camera with flash, organizer,

video, etc., that requires battery capacity to keep pace with the

power requirements.

 Digital camcorders

 Point of service (POS)

 Portable DVD players

 Portable hand-held solutions

 Portable media players

The AAT3620 is a pulse-width modulation (PWM) switch

mode/linear charger with high charging efficiency at the full

constant-current (fast charge) rate. Based on a 1.5 MHz PWM

step-down buck converter, the AAT3620 PWM switch mode

controls the constant-current charging mode up to 2.0 A, and

automatically switches to linear mode charging during the battery

conditioning low level current and the light load end-of-charging

current termination region. The full charging rate and the end-of-

charging current can be programmed with separate external

resistors. A shared charging current indication pin is available for

a Coulomb counter.

Features

 Input voltage range: 4.3 to 6.0 V

 Up to 2.0 A charging current capability

 1.5 MHz PWM/linear charger

 Over 90% full rate charging efficiency

 Integrated switching device

 “No BAT” detect

 Safety timer

Battery charger temperature and charging state are fully

monitored for fault conditions. In the event of an over-current,

over-voltage, short-circuit or over-temperature failure, the device

automatically shuts down. Two status monitor output pins are

provided to indicate the battery charging status and power source

status through two display LEDs. The AAT3620 also has a no-

battery detection feature, "No BAT", which requires the safety

timer.

 Integrated sense resistor

 Built-in reverse blocking feature

 Battery preconditioning/constant-voltage/constant-current

charging mode

 Programmable end-of-charging current

 1% constant-voltage mode regulation

 Built-in programmable charging timer

 Charging current indication pin

The AAT3620 is available in a thermally enhanced, space-saving

14-pin, 3 mm  3 mm TDFN package.

A typical application circuit is shown in Figure 1. The pin

configurations are shown in Figure 2. Signal pin assignments and

functional pin descriptions are provided in Table 1.

 Over-voltage, over-current, and over-temperature protection

 Battery over-temperature protection

 Power-on reset and soft-start

 Space-saving TDFN (14-pin, 3 mm  3 mm) package (MSL1,

260 ºC per JEDEC J-STD-020)
