8x Low-Side for 2 Stepper Motors with Stall Detection | E520.03 (*Driver IC)

Description

The IC drives 2 or 3 unipolar stepper motors and provides an optional stall detection for end position detection. For LED dimming a quasi logarithmic duty cycle is following the physiology of the human eye. With 3 PWM sources... read more
