MPQ6532GVE-AEC1-Z

MPQ6532 is a gate driver IC designed for three-phase brushless DC (BLDC) motor driver applications. It is capable of driving three half bridges, consisting of six N-channel power MOSFETs, up to 60V. The MPQ6532 integrates a regulated charge pump to generate gate drive power, and uses a bootstrap (BST) capacitor to generate a supply voltage for the high-side MOSFET (HS-FET) driver. An internal trickle-charge circuit maintains a sufficient HS-FET driver voltage even when the output is at 100% duty cycle. Internal safety features include configurable short-circuit protection (SCP), overcurrent protection (OCP). The pulse-width modulation (PWM), DIR, and nBRAKE inputs control the motor speed, direction, and braking, respectively. The MPQ6532 is available in a QFN-28 (4mmx5mm) package with an exposed thermal pad. Applications include three-phase brushless DC (BLDC) motors and permanent magnet synchronous motors (PMSMs), automotive actuators, pumps and fans.
