Other Parts Discussed in Thread: DRV8837,
Hello,
I saw this kind of question posted for DRV8837 here but wanted to check if the same would be true for DRV8231A.
Application: AC pile charging inlet lock
Issue:
Customer need unlock their charging plug when charging pile power down, so they connect a capacitor to the negative terminal of the motor. When the system is powered off, the switch is closed and the capacitor is discharged to drive the motor to rotate. But the current will also flow into VM through body diode, the reverse current will turn on LDO and repower other ICs. This is what the customer doesn't want. Do we have any solution about this issue?
