概述

DW09

GENERAL DESCRIPTION

The DW09 series product is a high integration solution for lithium- ion/polymer battery protection. DW09 contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. DW09 is put into an ultra-small SOT23-5 package and only one external component makes it an ideal solution in limited space of battery pack.

DW09 has all the protection functions required in the battery application including overcharging, overdischarging, overcurrent and load short circuiting protection etc. The accurate overcharging detection voltage ensures safe and full utilization charging.

The low standby current drains little current from the cell while in storage.

The device is not only targeted for digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring long- term battery life.
