产品名称： RY2231 一节锂离子和锂聚合物电池保护 IC
型号： RY2231
产片介绍：The RY2231 is a high integration solution for lithium-ion polymer battery protection

1.General Description

The RY2231 is a high integration solution for lithium-ion/polymer battery protection. RY2231 contains internal

power MOSFET, high-accuracy voltage detection circuits and delay circuits. RY2231 has all the protection

functions required in the battery application including overcharging, over discharging, 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.

The RY2231 do not require external resistor and capacitor, is available in a space saving DFN4-1×1 package.
