Stepper Motor Driver with Stall Detection (LIN/PWM Interface) | E523.60, E523.61 (*SoC/*Plug & Play)

This bipolar stepper-motor actuator provides a sensorless end position detection which also is able to detect 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 current 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 compatible 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 complete FLASH update can be done via high-speed-LIN communication.
