MP6500 스텝모터 드라이버 -디지털 전류 제어
(MP6500 Stepper Motor Driver Carrier, Digital Current Control)
개요
- 본 제품은 MPS사의 MP6500 마이크로스텝핑 바이폴라 스텝모터 드라이버입니다.
- MP6500은 1/8 스텝 마이크로스텝핑을 지원하며, 4.5V-35V에서 동작이 가능합니다.
- 방열판 없이 phase 당 1.8A까지 전달이 가능합니다.
- 이 제품은 마이크로컨트롤러가 디지털 핀 한쌍을 통해 동적으로 전류 제한을 제어할 수 있습니다.
특징
- Simple step and direction control interface
- Four different step resolutions: full-step, half-step, 1/4-step, and 1/8-step
- Adjustable current control lets you set the maximum current output, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
- Two current limit control options available:
- Potentiometer Current Control — this carrier version uses an on-board trimmer potentiometer to set the current limit up to 2.5 A
- Digital Current Control — this carrier version allows a microcontroller to dynamically adjust the current limit up to around 2 A
- Internal current sensing allows the driver to automatically adjust the decay mode as necessary to provide the smoothest current waveform
- 4.5 V to 35 V supply voltage range
- Can deliver 1.8 A per phase continuously without additional cooling
- Built-in regulator (no external logic voltage supply needed)
- Can interface directly with 3.3 V and 5 V systems
- Over-temperature thermal shutdown, over-current shutdown, short circuit protection, and under-voltage lockout
- 4-layer, 2 oz copper PCB for improved heat dissipation
- Exposed solderable ground pad below the driver IC on the bottom of the PCB
