DW01A

DW01A General 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. Ordering Information DW01A PACKAGE TYPE SOT-23-6 TEMPERATURE RANGE -40°C~+85°C OVERCHARGE PROTECTION 4.3V± 50mV Features Reduction in Board Size due to Miniature Package SOT-23-6. Ultra-Low Quiescent Current at 3μA (Vcc=3.6V). Overdischarge Current at 4 μA (Vcc=1.8 V). Precision Overcharge Protection Voltage 4.3V ± 50mV Two Detection Levels for Overcurrent Protection. Delay times are generated by internal circuits. No external capacitors required.
