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.

1 Absolute Maximum Ratings
Stresses beyond these absolute maximum ratings listed below may cause permanent damage to the device. These are stress rat-
ings only; operation of the device at these or any other conditions beyond those listed in the operational sections of this document
is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability. All voltages
with respect to ground. Currents flowing into terminals are positive, those drawn out of a terminal are negative.

1) The package was qualified at ambient temperatures -40...125°C,
for power dissipation < 1W also up to 150°C.
If higher ambient temperatures are focused please contact Elmos AG.
2) packages according to JEDEC standard JESD-51-6,7.
3) packages according to JEDEC standard JESD-51-5.
2) and 3) Using same structure on application board will lead to R
TH,JA
in the specified temperature region.
Power dissipation has to be taken into account based on R
TH,JA
values.
Actual thermal performance will depend on die-size, die-pad size, availability of an exposed die-pad and the concentration
of hot spots.
3) The maximum allowed power dissipation, calculated at TJ,max=150°C is a function of the ambient temperature and the
thermal resistance R
TH,JA
. It may be calculated as :
Pdmax=(TJ,max-TA)/RTH_JA.
