Monolithic Power Systems Inc. EVQ6527-F-00A

Overview

EVQ6527-F-00A from Monolithic Power Systems is an evaluation board for the MPQ6527 ten-channel half-bridge gate driver IC, supporting 5.5–40V input, 0.8A per channel output, serial SPI control, daisy-chain capability, and AEC-Q100 Grade 1 qualification in TSSOP28-EP package. It enables rapid validation of motor drive topologies in automotive and industrial motion control systems.

For engineers reviewing the EVQ6527-F-00A datasheet, EVQ6527-F-00A pinout, EVQ6527-F-00A application, or EVQ6527-F-00A equivalent, this board provides full access to all 10 half-bridge outputs (OUT1–OUT10), SPI interface signals (CLK, CS, DI, DO), enable (EN), and diagnostic monitoring points - with on-board 3.3V regulation, test points, and LED status indicators for real-time channel feedback.

Technical Context

The EVQ6527-F-00A implements a complete reference design for the MPQ6527, integrating its TSSOP28-EP footprint, external passive network (including 330μF input bulk cap, 10μF ceramic decoupling, and 100nF channel bypass caps), and discrete protection diodes (B340, 1N4148W) for high-side/low-side switching transients. All 10 half-bridges are independently controllable via SPI register writes.

It supports diagnostic readback of shorted-load, open-load, over-temperature, over-voltage, and under-voltage faults through dedicated status bits accessible via the serial interface. Standby quiescent current is minimized per MPQ6527 specification, enabling low-power system sleep modes without external bias circuitry.

FAQ

What power supply requirements must be met to operate the EVQ6527-F-00A?

The board requires a single 5.5–40 V DC input applied to the VIN and GND terminals. The on-board MPQ2013A regulator generates 3.3 V for logic; no external 3.3 V supply is needed. Input capacitance (330 μF) is provided, but users must ensure adequate current delivery for peak 0.8 A/channel loads.

How are the 10 half-bridge outputs configured and monitored?

Each of the 10 outputs (OUT1–OUT10) is controlled via SPI-accessible configuration registers. Status bits for short-circuit, open-load, temperature, and voltage faults are readable per channel. LEDs (BL-HUF35A-TRB) provide visual feedback when SW1 is enabled, mapping rotation direction for DC motor loads.

Does the EVQ6527-F-00A support daisy-chaining multiple MPQ6527 devices?

Yes - the board exposes all required SPI signals (CS, CLK, DI, DO) and includes termination resistors compatible with multi-device daisy chains. The MPQ6527's serial interface supports cascaded register writes and reads, allowing synchronized control of up to 16 devices on one bus.

What external components must be added to use the board with a brushed DC motor?

No external power-stage components are required: each half-bridge output connects directly to motor terminals. Users must add only the motor load and ensure proper heat sinking if operating continuously above 0.5 A per channel. Flyback diodes are already populated (D2–D19).

Is the EVQ6527-F-00A RoHS-compliant and AEC-Q100 qualified?

Yes - the board uses only RoHS- and halogen-free components, and the MPQ6527GF-R2 IC is AEC-Q100 Grade 1 qualified (−40°C to +125°C ambient). Full compliance documentation is available from MPS upon request.

Can the board be used without the GUI software?

Yes - all SPI signals are accessible via CN6 (2.54 mm dual-row header) and test points (CLK, CS, DI, DO, EN, GND). Engineers may interface directly with any microcontroller or logic analyzer using standard SPI timing; register maps and command sequences are defined in the MPQ6527 datasheet.
