Abstract
A driver circuit with power-down transient suppression includes an amplifier for driving a load coupled to an output of the amplifier, a ramp-down voltage generator having a capacitor and a resistor for generating a ramp-down voltage during power-down of the amplifier, and a differential transistor pair responsive to the ramp-down voltage for pulling-down current at the output of the amplifier during power-down of the amplifier.
