The TIDA-01353 reference design is a discrete MOSFET based three-phase ECM control module for driving brushless (BLDC) motors rated up to 375W in HVAC blower applications using a sensorless trapezoidal control method. The cycle-by-cycle overcurrent protection feature protects the power stage from over currents and the board can work up to an ambient temperature of 85°C. This design also incorporates opto-isolation for 5 preset blower speed terminals available to the user, and is a direct replacement reference design for permanent split capacitor (PSC) motors.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
