BQ24311DSGR Description

Short technical summary and product information.

The BQ24311DSGR from Texas Instruments is a battery protection IC designed for Li-ion battery applications. It continuously monitors input voltage, input current, and battery voltage to safeguard against charging circuit failures.

 

Key features include input overvoltage protection with a rapid response time of less than 1 µs, user-programmable overcurrent protection with current limiting, and battery overvoltage protection up to 30 V. The device also supports up to 0.3 A input current and is robust against false triggering due to current transients. It includes thermal shutdown for die temperature monitoring and an enable input for control by a processor, along with status indication for fault conditions.

 

This IC is housed in an 8-WSON (2x2) package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C. The BQ24311DSGR is suitable for applications requiring reliable protection for lithium-ion batteries.
