EVQ6533-U-01A

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.
