Product Overview

The BQ24315DSGR is an Overvoltage and Overcurrent Protection IC designed to provide protection to Li-ion batteries from failures of the charging circuit. The IC continuously monitors the input voltage, the input current and the battery voltage. The output acts as a linear regulator. The output is regulated to VO(REG)for inputs between VO(REG) and the overvoltage threshold. If an input overvoltage condition occurs, the IC immediately removes power from the charging circuit by turning off an internal switch. In the case of an overcurrent condition, it limits the system current at the threshold value and if the overcurrent persists, switches the pass element OFF after a blanking period. Additionally, the IC also monitors its own die temperature and switches off if it exceeds 140°C. The input overcurrent threshold is user-programmable. The IC can be controlled by a processor and also provides status information about fault conditions to the host.
  • Input overvoltage, with rapid response in <1µs
  • User-programmable overcurrent with current limiting
  • Battery overvoltage
  • Robust against false triggering due to current transients
  • Thermal shutdown
  • Enable input
  • Status indication - fault condition
  • Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
