Patent ID: 7405528

Claim:
An integrated circuit for supplying gate command signals to a high-side power switch, comprising: a gate drive circuit for applying turn on and turn off signals to the power switch; a command input circuit for providing set reset pulses to operate the gate drive circuit by processing input control pulses for controlling the high-side power switch and a rate of voltage change per unit time signal for controlling the gate drive circuit to produce a specified voltage applied to a gate of the high-side power switch during turn on or turn off times; and a gate voltage control circuit for converting the set and reset pulses to a voltage signal to control the gate drive circuit by varying the high-side power switch turn on and turn off time based on the voltage signal, wherein the set and reset pulses indicate a length of the input control pulses supplied to the high-side power switch, further comprising: a level shifting circuit coupled to the command input circuit for shifting a voltage level of the set and reset pulses.
