MPQ6531 Datasheet | Monolithic Power Systems

5V to 60V, Three-Phase Brushless DC Motor Pre-Driver AEC-Q100 Qualified DESCRIPTION The MPQ6531 is a gate driver IC designed for three-phase brushless DC motor driver applications. It is capable of driving three halfbridges consisting of six N-channel power MOSFETs up to 60V. The MPQ6531 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap capacitor to generate a supply voltage for the high-side MOSFET driver. An internal trickle-charge circuit maintains a sufficient high-side gate driver voltage at 100% duty cycle. Internal safety Features include programmable short-circuit protection, over-current protection, adjustable dead-time control,...
