Description: 马达控制，moto的专用芯片，比用CPU要好，简洁-Introduction
The AMIS− 30512 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. It has an on− chip
voltage regulator, reset− output and watchdog reset, able to supply
peripheral devices. The AMIS− 30512 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 and
control loops based on load− angle to adjust torque and speed. It is
using a proprietary PWM algorithm for reliable current control.
The AMIS− 30512 is implemented in I2T100 technology, enabling
both high− voltage analog circuitry and digital functionality on the
same chip. The chip is fully compatible with Platform: |
