MPQ6531GV-AEC1-Z

MPQ6531 5V to 60V, Three-Phase Brushless DC Motor Pre-Driver AEC-Q100 Qualified FEATURES 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. Wide 5V to 60V Input Voltage Range Charge Pump Gate Drive Supply Bootstrap High-Side Driver with TrickleCharge Circuit Supports 100% Duty Cycle Operation Low-Power Sleep Mode Programmable Short-Circuit Protection Over-Current Protection Adjustable Dead-Time Control to Prevent Shoot-Through Thermal Shutdown and UVLO Protection Fault Indication Output Thermally Enhanced Surface-Mounted Package Available in AEC-Q100 Grade 1     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, under-voltage lockout, and thermal shutdown.  The MPQ6531 is available in a 4mmx5mm QFN-28 package with an exposed thermal pad.    APPLICATIONS Three-Phase Brushless DC Motors Permanent Magnet Synchronous Motors Automotive Actuators, Pumps, and Fans All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
