General Description

The bq76200 device is a low-power, high-side, Nchannel system.

A high-side protection avoids ground disconnection in the system and also allows continuous munication between the battery pack and host system.

The device has additional PChannel FET control to allow low-current pre-charge to a deeply depleted battery, and a PACK+ voltage monitor control for the host to sense the PACK+ voltage.

Key Features

  • 1 CHG and DSG high-side NMOS FET drivers for battery protection fast FET turn-on and turn-off times.
  • Pre-charge PFET driver (for current-limited precharge of significantly depleted cell-pack).
  • Independent digital enable control for charging and discharging.
  • Minimal external components needed.
  • Scalable external capacitor-based charge pump to accommodate a different range of FETs in parallel.
  • High-voltage tolerant (100-V absolute maximum).
