Over current protection with improved stability systems and methods
Abstract:
Systems and methods are provided for improved stability of driver amplifiers. In one example, a system includes an NMOSFET power device operable to generate a current signal at a drain terminal. The system further includes a current comparison amplifier operable to amplify a difference signal comprising a difference between a replica current signal of the NMOSFET power device and a reference current signal to drive a current comparison amplifier voltage output signal. The system further includes a PMOSFET clamp device comprising a source terminal coupled to a gate terminal of the NMOSFET power device operable to limit a voltage at the gate terminal of the NMOSFET power device responsive to the current comparison amplifier voltage output signal.
