Abstract

The paper presents a Li-ion Battery protect chip and the system combined with the actual commercial products. By giving a complete global view diagram, the paper introduces the implementation of several modules of the chip, including the voltage comparator circuit, the delay circuit and battery status monitor circuit. Battery status monitor circuit is responsible for monitoring the status of the battery, including over-current, short-circuit and charger detection. In addition, the circuit trimming technology is provided in brief introduction in the paper.
