BQ76942: Status of DSG/CHG in SLEEP when DFETOFF/CFETOFF high

Part Number: BQ76942

As the title suggests,

On BQ76942, will the CFETOFF/DFETOFF pin status apply and make both DSG and CHG FETs off when the BQ is in SLEEP mode?

    Hello Predrag,

    The CFETOFF and DFETOFF will only disable the CHG and DSG FETs respectively when the CFETOFF and DFETOFF pins are asserted.

    Are you asking about SLEEP MODE because you want to use this feature in SLEEP mode? Yes, CFETOFF and DFETOFF can be driven high during SLEEP mode as the LDOs are ON in Sleep mode. This is possible.
