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.
Applications
ÿÿ Universal bipolar stepper motor actuators
