General Description

The BQ296xxx family is a high-accuracy, low-power overvoltage protector with a 2-mA regulated output supply for Li-Ion battery pack applications.

Each cell in a 2-series to 4-series cell stack is individually monitored for an overvoltage condition.

An internally fixed-delay timer is initiated upon detection of an overvoltage condition on any cell.

Key Features

  • 1 2-series, 3-series, and 4-series cell overvoltage protection (OVP).
  • Fixed delay timer to trigger FET drive output (3-s, 4-s, 5.5-s, or 6.5-s options).
  • Factory programmed OVP threshold (threshold range 3.85 V to 4.6 V).
  • Output options: active high.
  • High-accuracy overvoltage protection: ±10 mV.
  • Regulated supply output with self-disable and/or external enable/disable control.
  • Options: 3.3-V, 2.5-V, and 1.8-V (BQ2960, BQ2961).
