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.) allows for sensorless commutation. Protection and diagnostic
features as well as a step down switching regulator further reduce system cost and increase reliability.
