WSTDW01 - battery protection

General Description

The DW01 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.

Key Features

  • Reduction in Board Size due to Miniature Package SOT-23-6. Ultra-Low Quiescent Current at 3μA (Vcc=3.9V). Ultra-Low Power-Down Current at 0.1μA (Vcc=2.0V). Precision Overcharge Protection Voltage 4.3V ± 50mV for the DW01 Plus Load Detection Func.

WSTDW01 battery protection IC General Description The DW01 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 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 DW01 PACKAGE TYPE SOT-23-6 TEMPERATURE RANGE -40°C~+85°C OVERCHARGE PROTECTION 4.
