SLLSFH8B August 2021 – February 2022 MCT8316A
MCT8316A provides the option to configure the output PWM switching frequency of the MOSFETs through PWM_FREQ_OUT. PWM_FREQ_OUT has range of 5-100 kHz. In order to select optimal output PWM switching frequency, user has to make tradeoff between the current ripple and the switching losses. Generally, motors having lower L/R ratio require higher PWM switching frequency to reduce current ripple.
