General Description

This bipolar stepper-motor actuator provides a sensor-

less end position detection which also is able to de-

tect a blocked motor due to mechanical problems. This

function, called “stall detection” is performing within

a wide range of motors, supply voltages and ambient

temperatures. The stepper motor coil currents can be

controlled by the integrated micro-controller and a cur-

rent chopper principle. For precise absolute positioning

it is possible to supply and read out a potentiometer.

The state of the art LIN 2.2Rev.A / LIN2.1 transceiver

with auto-baud functionality is downwards compat-

ible to LIN1.3. For fast customer’s end-of-line FLASH

firmware programming, the FLASH-version is prepared

with a JTAG interface. Alternatively a partial or com-

plete FLASH update can be done via high-speed-LIN

communication.
