AMIS-30543 스텝 모터 드라이버
(AMIS-30543 Stepper Motor Driver Carrier)
개요
- 본 제품은 온세미컨덕터사의 AMIS-30543 마이스코스텝핑 바이폴라 스텝모터 드라이버를 탑재한 모듈입니다.
- 이칩은 SPI-조절 전류제한 기능, 11 스텝 모드(full-step에서 1/128-step까지), 스톨을 검출하는데 사용가능한 back-EMF 피드백, 과전류/과열 보호 기능을 가지고 있습니다.
- 보드는 6V-30V로 동작하며 방열판 없이 phase당 약 1.8A의 전류를 전달할 수 있습니다.
- 보드를 충분히 식혀준다면 코일당 3A까지 사용이 가능합니다.
특징
- Standard step and direction control interface
- SPI interface for configuring settings (e.g. step mode, current limit, sleep) and reading status registers
- Speed and load angle output that can be used for stall detection or closed-loop control of the torque and speed based on the load angle
- Eleven different step modes: full-step (uncompensated, compensated 1-phase, or compensated 2-phase), half-step (uncompensated or compensated), 1/4-step, 1/8-step, 1/16-step, 1/32-step, 1/64-step, and 1/128-step
- SPI-programmable current control (from 132 mA to 3 A) enables your microcontroller to adjust the peak-current limit on the fly as more or less torque or speed is needed
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- Low-EMI PWM with SPI-selectable voltage slopes
- Compatible with 5 V and 3.3 V microcontrollers
- Integrated 5V regulator that can be used to supply an external microcontroller
- Integrated watchdog function
- Open coil detection
- Thermal warning indicates when the driver is close to the thermal shutdown temperature
- Over-current status and shutdown (short-to-ground and shorted-load protection)
- Reverse voltage protection
