Abstract
Provided is an integrated circuit self-excitation resonance driver for an ultrasonic motor. An integrated circuit chip is utilized to work under the conditions of a self-excitation resonance state to solve the problem of frequency tracking inaccuracy of an existing driver. According to the circuit, a comparison amplifier circuit, a power-driven circuit and a regenerative feedback circuit are utilized to finish the self-excitation resonance state, and the goal is to establish a reference value circuit and a negative feedback automatic overturning circuit. A phase synchronizing signal output end and a phase synchronizing signal output authorization end are also designed. The driver is good in cost performance and market popularization and application prospect.
