RY2203 contains internal power MOSFET, high-accuracy voltage detection circuits and delay circuits. RY2203 has all the protection 特 c 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 r 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- 源 u term battery life. The RY2203 requires a minimal number of readily available, external ponents and is available in a space saving o CPC5 package. 矽 S RY2203 Typical Application Circuit ip 1KΩ R1 1 VDD 4 VM Charger + Ch+ Battery 0.1μF C1 5 VM Charger 2,3 GND Figure 1.
