4.1.2 Power saver or sleep mode for battery operated applications

MCT8316A can be configured to be in Sleep mode or Standby mode. For applications that operate using batteries, it is important to save power while the device is not spinning the motor.

MCT8316A enters sleep mode when speed input is held continuously below the speed threshold for SLEEP_TIME.

In sleep mode, all motor outputs are disabled, the charge pump is disabled, the AVDD regulator is disabled, and the serial communication bus is disabled. MCT8316A can be configured to be in sleep mode by configuring register bits DEV_MODE. Please note that in Sleep mode, GUI will lose connectivity as there will be no I2C communication.
