DRV8832-Q1: Fast switching the Controller

Part Number: DRV8832-Q1

Hello,

I am using the DRV8832-Q1 as a Dual H Bridge, and I am trying to disable the PWM getting 100% Duty Cycle.

My settings are as follow:

VCC 4V

ISENSE=GND

OUT1 - OUT2 Via 100Ohm for testing

IN2= 0

IN1 = 3ms pulses every 500ms

VREF -VSET Via 5k

VSET - GND Via 180K

FAULTn - Not Connected

When the IN1 Pulse is 25ms I get the PWM

When the IN1 Pulse is 3ms, the Drain (N Ch Fet) doesn't even start.

I would like to know what is the minimum pulse time I need to use and how to get the 100% DC

I have also tried to connect VREF to VSET directly and I get the same result.

Please advice
