General Description
The IC drives 2 or 3 unipolar stepper motors and pro-
vides an optional stall detection for end position detec-
tion. For LED dimming a quasi logarithmic duty cycle
is following the physiology of the human eye. With 3
PWM sources color LEDs can be driven in 3-color LED
mode (245Hz PWM). The Relay PWM mode automati-
cally adjusts the PWM to an effective supply voltage of
typ. 11V. All outputs are short circuit and over-temper-
ature protected with error read back capability. Switch
monitoring with control lamp combination with only 1
wire and output is possible.
