Production Data - Jan 28, 2016 Features General Description For 1 bipolar stepper or up to 3 DC motors Motor currents up to 2* 800mA (peak) Programmable chopper current values for sinus or customized micro-stepping 5.5V - 20V supply voltage (load dump 42V) Very low sleep mode current, typ. 30μA 8bit μController with assistance logic and - 256 Byte RAM, boot-loader - 8kByte FLASH or ROM (opt. firmware) - 64 Byte EEPROM for customer parameters 3 * Hall-sensor/potentiometer inputs+supply LIN 2.x, SAE J2602 or bidirect. PWM-interface compatible to LIN2.2Rev.A, 2.2, 2.1, 2.0, 1.3 QFN32L6 package This system-in-a-chip IC controls bipolar stepper actuators with current-choppered micro-stepping. The IC is controlled by a LIN2.x interface. It’s LIN-address can calculated by the “auto-addressing” feature (called “SNPD” in official LIN-specification). Alternatively the IC can be controlled by a PWM-interface, with diagnosis feedback. The integrated sensor-less “stall-detection” detects mechanical end-positions and stops the motor to reduce acoustical noise during initialization runs. The calculating heart is an 8-bit controller which is assisted by powerful circuitry. For absolute precise positioning, up to 3 Hall-sensors or potentiometers can read out. The IC can also drive up to 3 DC motors or other loads. ICs with FLASH-memory are programmable via JTAG interface or LIN in normal or high speed mode. The IC is available with standard firmware as well as with a development system for individual firmware.
