BQ294506 - Overvoltage Protection

Download the BQ294506 datasheet PDF. This datasheet also covers the BQ294502 variant, as both devices belong to the same overvoltage protection family and are provided as variant models within a single manufacturer datasheet.

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) <.
