MPQ6533 Datasheet | Monolithic Power Systems

Three-Channel Automotive Pre-Driver, AEC-100 Qualified DESCRIPTION The 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...
