EC9529A-Lithium Battery Protection Integrated Circ

EC9529A-Lithium Battery Protection Integrated Circ
General description
The EC9529A series is a highly integrated solution for lithium- ion/polymer battery protection. It contains advanced power MOSFET, high-accuracy voltage detection circuits and delay circuits. EC9529A is performed in ultra- compact SOT23-5 package and only one external component required, making it an ideal solution in limited space of battery pack. EC9529A has all the protection functions required in the battery application including over- charging, over- discharging, over-current and load short circuiting protection etc. The accurate over- charging detection voltage ensures safe and full utilization charging. The low stand- by current drains little current from the cell while storage. The device is not only targeting digital cellular phones, but also for any other Li-Ion and Li-Poly battery-powered information appliances requiring long- term battery life
