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 the automotive voltage requirements. |
