Monolithic Power Systems (MPS) MP6539C 3-Phase BLDC Motor Pre-Driver

Monolithic Power Systems (MPS) MP6539C 3-Phase BLDC Motor Pre-Driver is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications. It can drive three half-bridges, consisting of six N-channel power MOSFETs, up to 80V. The MP6539C uses a bootstrap (BST) capacitor (CBST) to generate a supply voltage for the high-side MOSFET (HS-FET) driver. An internal charge pump maintains the high-side (HS) gate driver if the output is held high for an extended period. Internal safety features include shoot-through protection, adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown.

The Monolithic Power Systems (MPS) MP6539C is similar to the MP6539 but does not include automatic BST charging or over-current protection (OCP). The MP6539C removes the VIN and LDO pins and is only powered from the VDD pin. The MP6539C is available in a QFN-28 (4mm x 5mm) package with an exposed thermal pad.
