DW01A HMsemi Battery Protection IC Data Sheet
Download Datasheet for Shenzhen H&M Semiconductor DW01A Battery Protection IC [7 pages 2017 pdf/zip]
Description
The DW01A battery protection IC is designed to protect lithium-ion/polymer battery from damage or degrading the lifetime due to overcharge, overdischarge, 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 DW01A 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.
