DW01A Datasheet Battery Protection

Manufacturer: H&M Semiconductor

Overview: DW01A General.

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 ponents 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.

Key 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.
