Using DRV8833 to power MCU

Is it possible to power MCU with VMM of DRV8833. If so what is the output voltage at VMM. I’d like to power both the Motors and the MCU with a single battery source.



Yes, it is possible to power an MCU using the VMM pin. As described in the pinout table on the DRV8833 product page, VMM gives access to the motor power supply after the reverse-voltage protection MOSFET, so it can be used to supply reverse-protected power to other components in the system.
