  • Patent number: 8050004
    Abstract: A power circuit includes a gate drive sever comparator circuit operable to disconnect a pre-drive transistor circuit from ground in response to an over voltage fault condition. A back-up gate drive comparator circuit operable to switch a reference directly into a multiple of shunt MosFets such that the multiple of shunt MosFets are turned on to reverse the over voltage fault condition until voltage drops and the gate drive sever comparator circuit and the back-up gate drive comparator circuit turn off to maintain a regulated voltage between comparator controlled limits.
    Type: Grant
