System for Battery Management and Protection

摘要

The present disclosure is directed to a system for battery management and protection. A battery protection circuit may include a power semiconductor switch and a control integrated circuit (IC). The battery protection circuit may be configured to regulate the charging and/or discharging of a battery and further prevent the battery from operating outside of a safe operating area based on a protection trip point (e.g. overcurrent detection point) of the protection IC. The protection IC may be configured to calibrate a protection trip point so as to compensate for process and temperature variations of on resistance (RSSon) of the power semiconductor switch.
