DRV8842: V3P3OUT tied to INx

Part Number:DRV8842

Hi team,

My customer is asking us what could happen when V3P3OUT is tied to IN1 or IN2. Both pins are connected to and driven by MCU.
My assumptions are;
- If MCU keep H on both pins, no problem could happen.
- If MCU drives the pin to L, the V3P3OUT is tied to L with low impedance. If MCU does not get damaged, V3P3OUT fall to low voltage.
What does happen on DRV8842 if V3P3OUT become low voltage?
