SLLSFH8A August 2021 – December 2021 MCT8316A
The ISD function is used to identify the initial condition of the motor and is enabled by setting ISD_EN to 1b. The initial speed, position and direction is determined by sampling the phase voltage through the internal ADC. ISD can be disabled by setting ISD_EN to 0b. If the function is disabled (ISD_EN set to 0b), the MCT8316A does not perform the initial speed detect function and proceeds to check if the brake routine (BRAKE_EN) is enabled.
