ONE-CELL LI-ION BATTERY PROTECTION IC

FEATURES

GENERAL DESCRIPTION

z Ideal for One-Cell Rechargeable Li-Ion

The AAT8660 series are designed to protect

one-cell rechargeable Li-Ion battery pack against

over-charge, over-discharge, over-current and

short circuit. They use CMOS process to provide

high accuracy voltage detection and low current

consumption.

Battery Packs

z High Accuracy Voltage Detection

z Low Current Consumption:

3μA Supply Current (Typical)

0.1μA Shutdown Current

Each of the AAT8660 devices incorporates

voltage comparators, bandgap reference voltage

generator, signal delay circuit, short circuit

detector, and digital control circuit.

z 3-Level Over Current Detection:

Over-Current Level 1 /Over Current Level 2

/ Short Circuit

z Wide Operating Temperature Range:

− 40^οC to + 85^οC

In the charge process, when the battery voltage is

charged to a value greater than V_C1(Over-Charge

z Small SOT26 Package

Threshold Voltage), the output of C_outpin

switches to the low level, i.e., the VN pin level.

The output of C_outpin will switch to high level

PIN CONFIGURATION

when the battery voltage falls lower than V_C2

(Over-Charge Release Voltage), or when the

charger is disconnected from the battery pack and

the battery voltage level ranges between V_C1and

V_C2.

D _out

GND

V_DD

During the discharge process, when the battery

voltage drops to a value lower than V_D1

(Over-Discharge Threshold Voltage), the output

of D_outpin switches to low level immediately

NULL

C_out

after the internal delay time elapses. The output

of D_outpin will switch to high level when the

battery voltage is at a level higher than V_D2

(Over-Discharge Release Voltage).
