bq76200 High-Side N-Channel FET Driver

Texas Instruments offers its bq76200, high-voltage battery pack front-end charge and discharge, high-side NFET driver

Image of Texas Instruments' BQ76200 High-Side N-Channel FET DriverTexas Instruments' bq76200 device is a low-power, high-side, N-channel system. The high-side protection avoids ground disconnection in the system and also allows continuous communication between the battery pack and host system. The device has additional P-Channel 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.

The independent enable inputs allow CHG and DSG FETs to be turned on and off separately, offering great implementation flexibility in battery systems.

The bq76200 device can be used with a companion analog front-end device such as the bq76920/30/40 family, a 3-series to 15-series cell analog front-end monitoring device, and a host microcontroller or dedicated state-of-charge (SOC) tracking gas gauge device.

Features
  • CHG and DSG high-side NMOS FET drivers for battery protection and fast FET turn-on and turn-off times
  • Pre-charge PFET driver (for current-limited pre-charge 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 max.)
  • Internal switch to enable pack-voltage sensing
  • Common and separate, charge and discharge path configuration support
  • Designed to work directly with bq76940, bq76930, and bq76920 battery monitors
  • Current consumption:
    • NORMAL mode: 40 µA
    • SHUTDOWN: < 10 µA max.
