AMIS-30522: Stepper Motor Driver

The AMIS-30522 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. AMIS-30522 contains a current-translation table and takes the next micro-step depending on the Clock signal on the NT, input pin and the status of the DIR direction) Register or input pin. The chip provides a so-called peed and load angleoutput. 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-30522 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-30522 is ideally suited for general-purpose stepper motor applications in the automotive, industrial, medical, and marine environment. With the on-chip voltage Regulator it further reduces the BOM for mechatronic stepper applications. By AMI Semiconductor, Inc.
