SLLU335A August 2021 – January 2022 MCF8316A
Thermal performance can be improved by minimizing power dissipation. Power dissipation across RDS(on), Switching losses and operating supply current dissipation are the major sources of Power dissipation in MCF8316A. Power dissipation across RDS(on) is fixed as MOSFETs are integrated in MCF8316A. Please follow below recommendations to minimize switching losses and operating supply current dissipation.
Step 1: Increase Slew rate [SLEW_RATE]
Please note that increasing Slew rate will increase EMI noise.
Step 2: Decrease PWM output frequency [PWM_FREQ_OUT]
Please note that decreasing PWM output frequency may lead to discontinuous phase current for very low inductance motors.
