DW01 One Cell Lithium-ion/polymer Battery Protection IC . 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
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.
ge (VODR) through charging.Overcurrent ProtectionIn normal mode, the DW01-P continuously monitors the ischarge current by sensing the voltage of CS pin. If the voltage of CS pin exceeds the overcurrent protection voltage (VOIP) beyond the overcurrent delay time (TOI1) period, the overcurrent protection circuit operates and discharging is inh
