The E523.30C from ELMOS SEMICONDUCTOR is a versatile system-in-a-chip designed for controlling bipolar stepper actuators with current-choppered micro-stepping. It integrates an 8-bit microcontroller with assistance logic, offering features like sensor-less stall detection for identifying mechanical end-positions. The device operates with a supply voltage range of 5.5V to 20V, with load dump protection up to 42V.
This IC supports motor currents up to 800mA peak per channel and can be controlled via a LIN 2.x interface (compatible with LIN2.2Rev.A down to 1.3) or a bidirectional PWM interface with diagnosis feedback. It includes 3 Hall-sensor or potentiometer inputs for precise positioning. The E523.30C is available with 8kByte FLASH or ROM firmware options and features a low sleep mode current of typically 30μA. It is housed in a QFN32L6 package and operates within a peak junction temperature range of -40°C to +165°C.
Applications include automotive head-light adjustment, front-grill shutters, and water valves. The device supports JTAG or LIN FLASH programming for ICs with FLASH memory. It can also drive up to 3 DC motors or other loads.
