Self Control Protector

SC Protector Self Control Protector Est. 1997/12/10 Rev.20 2002/11/27 Innovative way of safety control for Li-ion rechargeable battery At any moment, SC Protector system monitors the voltage of Li-ion rechargeable battery and its heater fuses the fuse at the same instant when the system detects the overcharge. Usual protection element takes long time to work because it works due to temperature rise of battery cells. The difference of SC Protector provides you high degree of freedom in the design of protection circuit. 1. Application Typical application of protection for a Lithium ion rechargeable battery from overcharging is shown in the figure below. ac FET Charger bd When the voltage between a and b exceeds the pre-set limit value, the output of the voltage detector IC becomes high and the FET is switched on. As a result, current flow through the heater of the protector, the fuses melt, and the battery stops to be charged any longer. Since the two fuses cut-off the voltage su.
