Monolithic Power Systems (MPS) MP6539B 100V 3-Phase BLDC Motor Pre-Drivers
Monolithic Power Systems (MPS) MP6539B 100V 3-Phase BLDC Motor Pre-Drivers can drive three half-bridges of six N-channel power MOSFETs up to 100V. The MP6539B uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal charge pump maintains the high-side gate drive if the output is high for an extended time. Internal safety features include shoot-through protection, adjustable dead-time control, under-voltage lockout (UVLO), and thermal shutdown. The MP6539B is available in TSSOP-28 (9.7mm x 6.4mm) and QFN-28 (4mm x 5mm) packages with an exposed thermal pad.
