DW01B
Overview
The DW01B battery protection IC is designed to protect lithium-ion / polymer battery from damage or degrading the lifetime due to over current 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 DW01B into the limited space of battery pack. The accurate ±50mV overcharging detection voltage ensures safe and full utilization charging.
