We use the VNHD7008AY to control the motor of a cargo lift. The lift has an emergency switch, which disconnects the battery from the circuit.
In case of an emergency cutout, the lift runs down while its motor generates a high voltage, which finally kills the VNHD7008AY.
To solve that problem I want to analyse the generator voltage (Pin VCC) and shortcut the H-bridge in case the generated voltage exceeds a limit.
This provides that the motor generated voltage passes the reverse battery protection transistor, so that it can supply the other parts of the circuit (microcontroller, etc).
My question:
If supply voltage comes from the motor side (Pin VCC) instead of battery side (Pin Vbatt), will the reverse battery protection transistor conduct so that voltage can pass from VCC pin to Vbatt pin?
