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)

BRUSHLESS VS BRUSHED DC MOTORS: WHEN AND WHY TO CHOOSE ONE OVER THE OTHERARTICLEMany motion control applications use permanent magnet DC motors. Since it is easier to implement control systems using DC motors compared to AC motors, they are often used when speed, torque, or position needs to be controlled. There are two types of commonly used DC motors: Brushed motors, and brushless motors (or BLDC motors). As their names imply, DC brushed motors have brushes, which are used...
