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.
