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
