Product Description

Description:

Simple step and direction control interface
The interface can connect directly with 3.3V and 5V systems
Support over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
Support short-to-ground and shorted-load protection
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
4-layer, 2 oz copper PCB for improved heat dissipation
Adjustable current control support you to set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45V maximum supply voltage
Built-in regulator (needed external logic voltage supply)
