control lamp

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.
