Abstract

See full text

An H-bridge driver has a drive signal generating circuit for generating a square-wave signal as a drive signal. The H-bridge driver also has a waveform shaping circuit for blunting the waveform of the drive signal at the rising and trailing edges thereof. The waveform shaping circuit has a first circuit for generating, in a rising period of the square-wave signal fed thereto, a first current having a positive peak at the center of the rising period, a second circuit for generating, in a trailing period of the square-wave signal fed thereto, a second current having a negative peak at the center of the trailing period, and a capacitor to which the first and second currents are fed. The waveform shaping circuit outputs the voltage across the capacitor as its output voltage.
