MP6543C Three-Phase BLDC Motor Drivers Monolithic Power Systems (MPS) MP6543C Three-Phase Brushless DC (BLDC) Motor Drivers feature three integrated half-bridges (consisting of six N-channel power MOSFETs), six pre-drivers, two gate driver power supplies, and three current-sense amplifiers. Each half-bridge includes an enable (EN) and pulse-width modulation (PWM) input. The motor drivers achieve up to 1.2A continuous output current (IOUT) across a 3V to 22V input voltage (VIN) range. The QFN-24 (3mm x 4mm) packaged MP6543C is designed for three-phase BLDC motor driver applications.
