DW01B Datasheet One-cell Lithiumbattery Protection

Manufacturer: ChipSourceTek

Overview: DW01B One-cell LithiumBattery Protection IC ◆◆ General.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

概述 The DW01B battery protection IC is designed to protect lithium-ion / polymer battery from damage or degrading the lifetime due to over current 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 DW01B into the limited space of battery pack.

The accurate ±50mV overcharging detection voltage ensures safe and full utilization charging.
