MPQ6533GUE-AEC1-P

MPQ6533 is a gate driver IC designed for automotive DC motor driver applications. The device drives six N-channel power MOSFETs to drive DC motors or other loads. The MPQ6533 integrates an LDO regulator to generate gate drive voltages for the low-side MOSFETs. The device also provides a charge pump that generates a voltage to drive an external N-channel MOSFET for reverse battery protection. The high-side gate drive is generated by the bootstrap capacitors and an internal charge pump, which allows for 100% duty cycle operation. An internal amplifier measures the voltage drop across the low-side MOSFETs. This allows the current to be measured without using shunt resistors. Internal safety features include configurable overcurrent protection (OCP), adjustable dead time control, undervoltage lockout (UVLO) and thermal shutdown. The MPQ6533 is available in a QFN-32 (5mmx5mm) package with an exposed thermal pad. Applications include automotive actuators and brushed DC motor drivers.
