A4001 : 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.

A4006 : FEATURES The A4006 is a single lithium battery charge indicator chip, using CMOS process to achieve, small size and ease of installation of portable products. The A4006 with built-in comparator and feedback loop, to materialize the detection of the four voltage point. By the internal trimming technology, you can ensure that the voltage detection accuracy of ±1 %. The output using OPENDRAIN structure, ease of customer use IO ports or LED indication.  Ultra-low current consumption:10uA  Built - in 4-way comparator, the detection of the four voltage point  The internal comparator with reasonable hysteresis, is easy to charge and discharge instructions.  High-precision detection voltage±.
