TMC603 DATA SHEET (V. 1.06 / 26. Mar. 2009) 1 TMC603 – DATASHEET Three phase motor driver with BLDC back EMF commutation hallFX™ and current sensing TRINAMIC Motion Control GmbH & Co. KG Sternstraße 67 D – 20357 Hamburg GERMANY www.trinamic.com ® 1 Features The TMC603 is a three phase motor driver for highly compact and energy efficient drive solutions. It contains all power and analog circuitry required for a high performance BLDC motor system. The TMC603 is designed to provide the frontend for a microcontroller doing motor commutation and control algorithms. It directly drives 6 external N-channel MOSFETs for motor currents up to 30A and up to 50V and integrates shunt less current measurement, by using the MOSFETs channel resistance for sensing. Integrated hallFX (pat. fil.) allows for sensorless commutation. Protection and diagnostic features as well as a step down switching regulator further reduce system cost and increase reliability. Highlights Up to 30A motor current 9V to 50V operating voltage 3.3V or 5V interface 8mm x 8mm QFN package Integrated shunt less current measurement using power MOS transistor RDSon hallFX™ sensorless back EMF commutation emulates hall sensors Integrated break-before-make logic: No special microcontroller PWM hardware required EMV optimized current controlled gate drivers – up to 150mA possible Overcurrent / short to GND and undervoltage protection and diagnostics integrated Internal QGD protection: Supports latest generation of power M...
