A4001

AiT Semiconductor Inc. www.ait-ic.com A4001 BATTERY MANAGEMENT ONE CELL LITHIUM-ION/POLYMER BATTERY PROTECTION IC DESCRIPTION FEATURES The A4001 battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, over discharge, and/or overcurrent for one-cell lithium-ion polymer battery powered systems, such as cellular phones The ultra-small package and less required external components make it ideal to integrate the A4001 into the limited space of battery pack. The accurate 50mV overcharging detection voltage ensures safe and full utilization charging. The very low standby current drains little current from the cell while in storage The A4001 is available in SOT-26 package. ORDERING INFORMATION  Reduction in Board Size due to Miniature  Ultra-Low Quiescent Current at 3uA  Ultra-Low Power-down Current at 0.1uA  Precision Overcharge Protection Voltage 4.3V+50mV for the A4001  Load Detection Function during Overcharge Mode  Two Detection Levels for Overcurrent Protection  Delay times are generated by internal circuits.
