Advanced Analog Technology, Inc. AAT8636 Series Details are subject to change without notice ONE-CELL LI-ION BATTERY PROTECTION IC FEATURES Ideal for One-Cell Rechargeable Li-Ion Battery Pack. Low Current Consumption 3.0µA …………..Supply Current (Typical) 0.1µA …………..Standby Current High Withstand Voltage Absolute Maximum Ratings..22V ( VDD − VN ) GENERAL DESCRIPTION The AAT8636 series are protection ICs designed to safeguard one-cell rechargeable Li-Ion battery pack against over charge, over discharge, over current, and short circuit. The AAT8636 series use advanced high voltage CMOS process to provide high accuracy voltage detection and low current consumption. The AAT8636 series incorporate a reference unit and three voltage detectors. During the charging process, when the cell voltage ( VDD ) is charged to a value higher than the over charge threshold voltage ( VC1 ), the over charge detector (COM1) will switch the output pin ( C OUT ) to a low level within a delay time ( t C1 ), and thus turning off the High Accuracy Voltage Detection Over Charge Detector…………... ± 20mV Over Discharge Detector………. ± 2.5% Over Current and Short Circuit Protection Wide Operating Temperature Range − 40 o C to 85 o C www.DataSheet4U.com Ultra Small Package……..SOT26 PIN CONFIGURATION MOSFET connected to the charging path. The C OUT pin may change to high level again when the VDD voltage falls below “ VC1 − VHYS ”, or when VDD falls below VC1 while the charger is disconnected...
