摘要
超声电机作为新型电机,其电机驱动器的设计至关重要.基于0.18 μm高压CMOS工艺设计了一款适用于超声电机驱动器的双H桥集成电路,本集成电路包含两个相同的独立裸芯,搭配简单的外围电路能够实现两路不同相位电压的输出.同时,内部集成了逻辑控制模块可兼容TTL、CMOS两种输入电平,集成自适应死区控制可避免同一桥臂直通.最后,通过验证板实测可满足100 kHz的两路不同相位电压的输出,可完成对超声电机的有效驱动.
Abstract
Ultrasonic motor as a new type of motor,the design of motor driver is very important.Based on 0.18 μm HV CMOS process,this article designed a dual H-bridge integrated circuit suitable for ultrasonic motor driver.The integrated circuit contains two identical independent die.Paired with simple peripheral circuits,it can produce two independent different-phase voltage out-puts.In addition,the internal integrated logic control module is compatible with both TTL and CMOS input levels.The integrated adaptive dead-time control module avoids simultaneous conduction of both arms of the bridge.Finally,through demo board test virification,it can output two different-phase voltage at 100 kHz.It can be seen that this circuit can effectively drive an ultrasonic motor.
