Control algorithms previously only found in much more complex servo drives can now be realized with a minimum of external components. The TMC603 directly drives 6 external N-channel MOSFETs for motor currents up to 20A and up to 50V. It integrates current measure ment without the need for high current sense resistors, and the sensorless commutation circuitry HallFX™. Its integrated support for sine commutation as well as for back EMF sensing and com mutation saves cost and allows for maximum drive efficiency. Depending on the desired commutation scheme and the bus interface requirements, the TMC603 forms a complete motor driver system in combination with an external 8 bit processor or with a more powerful 32 bit processor. Protection and diagnos tic features as well as a step down switching regulator further reduce system cost and increase reliability. The TMC603 also supports control of three phase stepper motors as well as two phase stepper motors using two devices. low power dissipation integrated phase current measurement via RDSon of power MOSFETs sensorless back EMF commutation hallFX™ (hall sensor like signals - phase shift free) integrated break-before-make logic: no spe- cial microcontroller PWM hardware required integrated overcurrent / short to GND and undervoltage protection and diagnostics integrated step down switching regulator up to 500mA / 300kHz ELECTRICAL DATA up to 20A motor current 9V to 50V operating voltage EMV optimized current controlled gate driv- ers - up to 150mA internal Q GD protection: Supports latest generation of power MOSFETs INTERFACE 3.3V or 5V interface• PACKAGE QFN52 package 8 x 8 mm² RoHS compliant 10 mm
