求推荐一款镜头超声波马达驱动芯片

Other Parts Discussed in Thread: TMS320DM368, DRV8833

马达类型为两相输入,行波型微型超声波马达。电机类型马达为压电超声电机,电机数量暂定为1个。芯片要求额定输入电压最好为12V以下,5V、3.3V、1.8V均可,对电流无特殊要求。芯片用来驱动单反镜头上的超声波马达,用TMS320DM368对驱动芯片进行控制。

芯片主要特性:1、能做到整步、半步和细分可调?

                        2、输出电流可调?

                        3、工作温度范围: -40℃ 至85℃
