Monolithic Power Systems Inc. EVQ6626-F-00A

Overview

EVQ6626-F-00A from Monolithic Power Systems is an AEC-Q100 Grade 1 qualified evaluation board for the MPQ6626 six-channel half-bridge motor driver IC, supporting 5.5V–40V input voltage and 0.8A per channel output current, with SPI serial control interface and integrated diagnostics including open-load, short-circuit, over-temperature, over-voltage, and under-voltage detection-designed for automotive motor control validation.

For engineers reviewing the EVQ6626-F-00A datasheet, EVQ6626-F-00A pinout, EVQ6626-F-00A application, or EVQ6626-F-00A equivalent, this board enables rapid functional verification of MPQ6626's six independently controllable half-bridges, real-time register configuration via GUI, and fault response characterization under defined load and supply conditions.

Technical Context

The EVQ6626-F-00A implements full hardware-level access to the MPQ6626 TSSOP-28EP driver IC, exposing all six OUTx terminals, SPI signals (CLK/CS/DI/DO), EN, VCC, and VS rails. It integrates a 3.3V MPQ2013AGQ-33-Z LDO for logic power and discrete test points for every signal node.

Board-level diagnostics include LED-based direction indicators per H-bridge pair (via SW1), on-board current-sense resistors, and fuse-protected VIN input. The schematic uses 100nF ceramic decoupling at each VS pin and 330μF bulk capacitance to support transient load testing up to 0.8A per channel.

FAQ

What is the primary function of the EVQ6626-F-00A?

The EVQ6626-F-00A is a dedicated evaluation board for the MPQ6626 hex half-bridge motor driver IC. It provides complete electrical access to all six output channels, SPI control lines, and diagnostic signals, enabling functional validation, timing analysis, and fault-mode testing without custom PCB design.

Does the board include a built-in power supply for logic voltage?

Yes-the board integrates the MPQ2013AGQ-33-Z, a 3.3V step-down regulator delivering up to 300mA, which powers the MPQ6626's logic interface and GUI communication circuitry. No external 3.3V source is needed for basic operation.

How are motor direction and status indicated on the board?

Direction is shown via dual-color LEDs (green/red) per H-bridge pair (e.g., OUT1/OUT2), activated when SW1 is enabled. Each LED pair lights based on current flow polarity through the associated half-bridge, providing immediate visual feedback during SPI-controlled actuation.

Can the EVQ6626-F-00A be used for over-current protection testing?

Yes-test results in the official documentation confirm OCP activation when any OUTx is shorted to GND, VIN, or another OUTx. The board sustains repeated OCP events without damage and reports fault status via MPQ6626's diagnostic registers accessible through the GUI.

Is the board compatible with standard SPI host controllers?

Yes-the CN6 connector exposes standard SPI signals (CLK, CS, DI, DO) at 3.3V logic levels, fully compatible with common microcontroller development platforms (e.g., STM32 Nucleo, Arduino Due) and commercial SPI analyzers without level-shifting.

What package does the mounted MPQ6626 IC use?

The board mounts the MPQ6626GF-AEC1 in a TSSOP-28EP (exposed pad) package, with thermal vias and copper pour optimized for heat dissipation during sustained 0.8A per channel operation at ambient temperatures up to 85°C.
