DC-input BLDC motor drive
Overview
Our integrated circuits and reference designs help you create compact, fully protected and efficient direct current (DC) input speed-controlled brushless direct current (BLDC) drives with smooth torque and accurate speed control. SoC with integrated sensorless trapezoidal or vector control ease use and reduce time to market.
Design requirements
DC-input BLDC drive designs often require:
- Small form factor, efficient and protected power stage.
- Efficient small form factor non-isolated and isolated power supplies.
- IEC-compliant isolated analog and digital interfaces.
- Motor driver with hardware-integrated sensorless trapezoidal or vector control.
