MPQ6533 - Three-Channel Automotive Pre-Driver

General 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.

Key Features

  • include configurable over-current protection (OCP), adjustable dead time control, under-voltage lockout (UVLO), and thermal shutdown. The MPQ6533 is available in a QFN-32 (5mmx5mm) package with an exposed thermal pad.

MPQ6533 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 allows the current to be measured without using shunt resistors.
