Inquiry regarding PWM driving of Inductive Loads with VND5T100LAJ-E

Hello,

I am evaluating the VND5T100AJ-E for an automotive application where I need to drive a 24V contactor. My design requirement is i need to drive the IC through the PWM signal as input.

I have reviewed the datasheet but do not see explicit PWM frequency ratings. My concerns are:

  1. Does the VND5T100AJ-E support continuous PWM switching for an inductive load?

  2. If this device is not recommended for PWM, could you suggest a similar specification alternative part with the same specifications  that is specifically designed for PWM input @stmicro

Welcome @Chiranjeevi9391, to the community!

TheVND5T100LAJ-E can also switch inductive loads, including via PWM. The switching frequency can be estimated based on the turn-on and turn-off delay times.

What PWM frequency are you planning to use?

Regards

We are planning to operate at max frequency of MHz's range.
