Elmos Semiconductor AG: Stepper motor driver with stall detection

(DGAP Corporate News Via Acquire Media NewsEdge) (DGAP-Media / 22.05.2014 / 15:10) E523.30/37 for automotive applications with LIN2.x interface With the E523.30/37, Elmos is presenting a motor driver for bipolar stepper motors. The sensorless end position / stall detection is a special highlight. For the most demanding motor position detection requirements, up to 3 additional Hall sensors or potentiometers can also be connected to the IC. The Elmos component can be integrated directly into the actuator which saves on installation space.

In addition to angular positioning, another highlight of the E523.30 is that the modules are addressed with LIN Auto-Addressing. Alternatively, this module can also be controlled with a PWM interface. A version without LIN-Auto-Addressing is also available (E523.37).

The components are also available with a "ready to use" LIN2.1 or LIN1.3 software and PC-GUI option. The tool environment and compact LIN routines can be made available for in-house software development.

Potential application fields or applications for the E523.30/37 include stepper motors or DC drives for a variety of automotive applications such as radiator grill shutter, headlight or valve controllers.

The ICs feature a microcontroller, 8K Flash memory, 4K ROM and a 64 byte EEPROM. The voltage range is 5.5 to 18 V (load dump up to 42 V). The current limiting is controlled at the driver stage and can reach up to 2x800mA. The module only consumes 50µA in sleep mode. The product is available in a QFN32L6 housing.
