AM305321R1DBGEVB: Daughter Board Stepper Driver NQ Evaluation Board

The AM305321R1DBGEVB is a form factor daughter board for driving bipolar stepper motors. The daughter board can be interfaced via I/O pins and the SPI bus to an external microcontroller. In conjunction with the evaluation kit AMIS305XXGEVK it forms a complete solution turning high level commands from a CAN node in well defined motions. The design incorporates the lowest bill of materials, small board size and perfect matched thermal resistance allowing to drive 1.6A at elevated ambient temperature or even 3.2A under certain conditions.

Note: This board must be used with the AMIS305XXGEVK Industrial Stepper Motor Driver Kit.

  • Nominal current of 1.6A (3.2A under certain conditions)
  • Fully integrated current sensing
  • 6V-30V supply voltage
  • On chip 5V/50mA regulator
  • (Watchdog) reset output
  • Compatible with 5V and 3.3V microcontrollers
  • Next step and motion direction input
  • Speed and load-angle output
  • Diagnostics information
  • Thermal warning and thermal shutdown
  • Programmable PWM frequency and slope control
