AMIS30511集成電路（IC）的電機驅動器控制器規(guī)格書PDF中文資料

AMIS30511屬于集成電路（IC）的電機驅動器控制器。由安森美半導體公司制造生產的AMIS30511電機驅動器，控制器產品屬于電機驅動器和控制器電源管理集成電路 (PMIC) 系列，可用于控制或操作從某電源施加到電機或相關機電執(zhí)行器的電源。所實現(xiàn)的具體功能和特性集根據(jù)預期負載和預期應用的特性有很大差異，范圍從用于有刷電機的簡單開環(huán)速度控制到基于步進電機的高級閉環(huán)運動控制。

Introduction

The AMIS?30511 is a micro?stepping stepper motor driver for bipolar stepper motors. The chip is connected through I/O pins and a SPI interface with an external microcontroller. The AMIS?30511 contains a current?translation table and takes the next micro?step depending on the clock signal on the “NXT” input pin and the status of the “DIR” (=direction) register or input pin. The chip provides a so?called “speed and load angle” output. This allows the creation of stall detection algorithms, step loss detection, and control loops based on load?angle to adjust torque and speed. It is using a proprietary PWM algorithm for reliable current control.
