onsemi ECS640A (Brazos) - ecoSpin™

ecoSpin™ NFMECS640A0 600V BLDC motor controller for compressors and HVAC

The ecoSpin^TM ECS640A is an easy to use, multi−purpose 3−phase BLDC controller/driver.  The small footprint simplifies board layout and enables scalable power levels with discrete power devices. The controller supports Trapezoidal, Sinusoidal, and FOC commutation and has an industry first Direct Torque and Flux Control (DTFC) on an ARM Cortex M0+ uC. The device supports both sensored and sensorless architectures.
