Introduction

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.

Features

• Reduction in Board Size due to Miniature Package SOT-23-6.
• Ultra-Low Quiescent Current at 3μA (Vcc = 3.6V).
• Overdischarge Current at 4μA (VCC = 1.8V).
• Precision Overcharge Protection Voltage 4.3V ±50mV
• Two Detection Levels for Overcurrent Protection.
• Delay times are generated by internal circuits.
• No external capacitors required.

Applications

• Protection IC for One-Cell Lithium-Ion / Lithium-Polymer Battery Pack
