TCS9922
One Cell Li-ion and Li-poly Battery Protection IC
Product Description
The TCS9922 is a high integration solution for lithium-ion/polymer battery protection. TCS9922 contains internal power MOSFET, high-accuracy voltage detection circuits and delay circuits. TCS9922 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 TCS9922 requires a minimal number of readily available, external components and is available in a space saving DFN2x2-6 package.
