Abstract :
A battery protection circuit is presented. The circuit is composed of charge/discharge control IC and power MOSFET. Simulation was performed with 0.5 μm BCD technology and the RDS(ON) of the power MOSFET is 38 mΩ. The circuit reduces loss by RDS(ON) resistance more than the previous circuit. And it improves efficiency of the battery pack. Power dissipation of the power MOSFET is about 68 mW, when the current of the MOSFET is 1.3 A.
