DRV8243-Q1: VM off during operation

Hello team,

Is it okay for DRV8243 to operate in condition where VM is going to be OFF constantly?

My customer is considering to use DRV8243 for solenoid with the configuration below.

+24V -> TPS1663(eFuse) -> VM of DRV8243

They put TPS1663 to reduce the current pulled by the solenoid from the power supply, and compensate the remaining current from Cout CAP.

However, when the customer drove the solenoid, the TPS1663 disconnects the 24V power supply for VM constantly, and he is worried if it is going to affect the DRV8243 operation.

Best Regards,
