Method of controlling slope and dead time in an integrated output buffer with inductive load

摘要

A method and apparatus independently controls the increasing rate and the decreasing rate a P-channel power FET and an N-channel power FET driving an inductive load. Circuits inhibit turning ON the P-channel FET until the voltage on the gate of the N-channel FET falls below its turn-on voltage threshold, and turning ON the N-channel FET until the voltage on the gate of the P-channel FET falls below its turn-on voltage threshold.
