Three Phase Motor Driver

tation HallFX™ and Current
Sensing
INFO The TMC603 is a three phase BLDC motor driver IC for highly
compact and energy efficient drive solutions. 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.
