Download the BQ294524 datasheet PDF (BQ294502 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for overvoltage protection.

Description

The BQ2945xy family of products is a secondary-level voltage monitor and protector for Li-ion battery pack systems.

Each cell is monitored independently for an overvoltage condition.

Features

  • 2-series and 3-series cell overvoltage monitor for secondary protection.
  • Fixed programmable delay timer.
  • Fixed OVP threshold.
  • Available range from 3.85 V to 4.6 V.
  • Fixed OVP delay option: 4 s or 6.5 s.
  • High-accuracy overvoltage protection: ±10 mV.
  • Low power consumption ICC ≈ 1 µA (VCELL(ALL) <.
