Hi there, my team is using three of the DRV8874 for BDC bidirectional control. We wish to use these drivers in PWM mode where PMODE = HIGH.
1. Is there any problem with PMODE = 5V while we use a 3.3V PWM?
2.. For unidirectional PWM control, can we tie IN2 to 5V and use 3.3V PWM on IN1?
3. 5V is connected to a load switch which will be turned off in low power mode. Any concerns with the driver glitching due to the different PMODES? During this turn off time, the drivers will also be shutdown
Would it be beneficial in keeping PMODE tied low for simplicity sakes?
