3 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 communication 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.

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 (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.
