MPQ6533-AEC1

6V to 40V, Three-Channel Automotive Pre-Driver, AEC-100 Qualified

Datasheet

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 device integrates a low-dropout (LDO) regulator to generate gate drive voltages for the low-side MOSFETs (LS-FETs). 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 LS-FETs. This allows the current to be measured without using shunt resistors.

Internal safety 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.

Advantages include:

Integrated LDO Regulator for Gate Drive
Charge Pump for External N-Channel MOSFET Reverse Battery Protection
Internal Current-Sense Amplifier, Serial Peripheral Interface (SPI), and Fault Indication Output
Robust Protection Functions Include Configurable Over-Current Protection (OCP), Adjustable Dead-Time Control, Under-Voltage Lockout (UVLO), and Over-Temperature Protection (OTP)

The EVQ6533-U-01A evaluation board is designed to demonstrate the capabilities of the MPQ6533, a three-channel automotive pre-driver with serial input control. The device is suitable for automotive actuators and brushed DC motor driver applications.

The MPQ6533 integrates a low-dropout (LDO) regulator to generate gate drive voltages for the low-side MOSFETs (LS-FETs). It also provides a charge pump that generates a voltage to drive an external N-channel MOSFET for reverse battery protection. The high-side (HS) gate drive voltage is generated by the bootstrap (BST) capacitors (C_BST) and an internal charge pump, which allows for 100% duty cycle operation.

An internal amplifier measures the voltage drop across the LS-FETs. This allows the current to be measured without using shunt resistors.

Internal safety features include configurable over-current protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and over-temperature (OT) shutdown.

The MPQ6533 is available in a QFN-32 (5mmx5mm) package with an exposed thermal pad, and it is AEC-Q100 qualified.
