ABSTRACT:
A HDD write driver circuit (10) having a boost current overshoot programmed by a plurality of pull-up devices (MP35, MP36, MP39, MP45). The pull-up strength of an inverter (20) is adjustably selected by programming pull-up PMOS devices, and less power is dropped across a resistor (R41) such that there is less boost current overshoot when an overshoot MSB is low.
