BQ2973 - Cost-Effective Voltage/Current Protection

Download the BQ2973 datasheet PDF. This datasheet also covers the BQ2970 variant, as both devices belong to the same cost-effective voltage/current protection family and are provided as variant models within a single manufacturer datasheet.

Description

The BQ2970 battery cell protection device provides an accurate monitor and trigger threshold for overcurrent protection during high discharge/charge current operation or battery overcharge conditions.

Features

  • Input voltage range pack+: VSS.
  • 0.3 V to 12 V.
  • FET drive:.
  • CHG and DSG FET drive output.
  • Voltage sensing across external FETs for overcurrent protection (OCP) is within ±5 mV (typical).
  • Fault detection.
  • Overcharge detection (OVP).
  • Over-discharge detection (UVP).
  • Charge overcurrent detection (OCC).
  • Discharge overcurrent detection (OCD).
  • Load short-circuit detection (SCP).
  • Zero voltage char.
