The bq76200 device is a low-power, high-side, N-channel system. Ahigh-side protection avoids ground disconnection in the system and also allows continuouscommunication between the battery pack and host system. The device has additional P-Channel FETcontrol to allow low-current pre-charge to a deeply depleted battery, and a PACK+ voltage monitorcontrol for the host to sense the PACK+ voltage.
The independent enable inputs allow CHG and DSG FETs to be turned onand off separately, offering great implementation flexibility in battery systems.
The bq76200 device can be used with a companion analog front end (AFE)device such as the bq76920/30/40 family, a 3-series to 15-series Cell Analog Front End Monitoring,and a host microcontroller or dedicated state-of-charge (SOC) tracking gas gauge device.
