  • Drive circuit for reducing inductive kickback voltage
    Patent number: 7639064
    Abstract: In one embodiment a drive circuit includes two comparators which are adapted to sense kickback voltage generated in an inductive load and conduct two field-effect transistors connected to ground in a very short period of time so as to quickly reduce the kickback voltage to a minimum value. In another embodiment only one comparator is provided.
