Patent ID: 7746148

Claim:
A high-side driver, comprising: a first impedance element having a terminal electrically coupled with a power supply; a first switch electrically coupled in parallel with the first impedance element; a second impedance element has a terminal electrically coupled with another terminal of the first impedance element; a first transistor having a drain electrically coupled with another terminal of the second impedance element; a third impedance element having a terminal electrically coupled with the power supply; a second switch electrically coupled in parallel with the third impedance element; a fourth impedance element having a terminal electrically coupled with another terminal of the third impedance element; a second transistor having a drain electrically coupled with another terminal of the fourth impedance element; a signal generator has a first pulse output terminal and a second pulse output terminal, wherein the first pulse output terminal is electrically coupled with a gate of the first transistor, the second pulse output terminal is electrically coupled with a gate of the second transistor; a latch circuit having a set terminal, a reset terminal and a first output terminal and a second output terminal, wherein the set terminal is electrically coupled with the drain of the first transistor, the reset terminal is electrically coupled with the drain of the second transistor and another terminal of the fourth impedance element, the first output terminal is electrically coupled with the first switch, the second output terminal is electrically coupled with the second switch; and a controller for controlling the signal generator to selectively output a first pulse signal or a second pulse signal.
