BLDCs offer even higher levels of efficiency, providing better control over a wider dynamic range and greater torque. Being brushless-effectively contactless from an electrical standpoint—they eliminate the electrical interference common to brushed DC motors. This reduction in electromagnetic interference can be crucial for the sensitive components in Engine Control Units (ECUs). Moreover, BLDCs avoid the arcing and subsequent wear associated with brushed commutation, leading to decreased performance and potential failure in brushed DC motors.

Specifically, this pertains to selecting a device with a breakdown voltage that provides ample protection against transients. For example, for a BLDC operating from a 12V supply, a breakdown voltage of 40V would suffice. Similarly, in a 24V system, a MOSFET with a breakdown voltage of 60V would provide satisfactory protection. TSC provides the 40V, 60V, 100V with PDFN33, PDFN56 etc., package for the reference design.
