Brushless DC Motors

Brushless DC Motors

With higher efficiency and reliability than brushed motors, brushless DC motors (BLDC) are becoming more popular in home appliances and consumer electronics. As efficiency standards for these applications continue to strengthen, better power conversion technology is also required to minimizes total power losses and simplify design.

BridgeSwitch integrated half-bridge motor driver family by Power Integration features high and low-side advanced FREDFETs (Fast Recovery Diode Field Effect Transistors) with integrated lossless current sensing, resulting in efficiencies of over 98.5% in brushless DC motor drive applications up to 300 W. Superior efficiency and distributed thermal footprint architecture eliminate the need for a heatsink, reducing system cost and weight.
