AMIS-30521: Stepper Motor Driver

The AMIS-30521 is a micro-stepping stepper Motor Driver for bipolar stepper motors. The chip is connected through I/O pins and an SPI Interface with an external Microcontroller The AMIS-30521 contains a current-translation table and takes the next micro-step depending on the Clock signal on the XT nput pin and the status of the DIR direction) Register or input pin. The chip provides a so-called seed and load angle outut. 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-30521 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. The AMIS-30521 is ideally suited for general-purpose stepper motor applications in the automotive, industrial, medical, and marine environment. By AMI Semiconductor, Inc.
