DW01 Plus
One Cell Lithium-ion/Polymer Battery Protection IC
General Description
The DW01 Plus 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 DW01 Plus
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.
Ordering Information
