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.
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, up to 50V operating voltage 3.
3V or 5V interface 8mm x 8mm QFN package Integrated dual range high precision current measurement amplifiers Supports shunt less current measurement using power MOS transistor RDSon 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 MOSFETs Integrated supply concept: Step down switching regulator up to 500mA / 300kHz Common rail charge pump allows for 100% PWM duty cycle
Applications Motor driver for industrial applications Integrated miniaturized drives Robotics High-reliability drives (dual position sensor possible) Pump and blower applications
Motor type 3 phase BLDC, stepper, DC motor Sine or block commutation Rotor position feedback: encoder or hall sensor
