Part Number: TPS92630-Q1

Hello team,

I would like to know the type of PWM and EN pins of TPS92630-Q1. Are these CMOS inputs? Also, are there any recommendations of series resistors on EN/PWMx/FAULT pins which are connected MCU?

Regards,
RYO

EN pin threshold is 0.7V/2V, PWM input is using a accurate comparator.

Normally there is no need to put a resistor in series with input pins, but recommend to add a 100k pull down resistor on each pin as the internal pull down current is very low, to avoid floating state.
