1. Overview

️· Product: EVQ6526-R-00A Evaluation Board
️· Purpose: Designed to demonstrate the functionality of the MPQ6526 Six Half-Bridge Motor Driver IC.
️· Functionality: Allows for flexible adaptation of loads and serial data interface control.
️· Power Requirements: 7V to 28V DC Input, with a maximum current draw of 3A.

2. Key Features

️· Flexible Load Adaptation: Offers easy adaptation of loads through connectors (CN4-CN7).
️· Serial Data Interface: Supports serial communication for control.
️· Voltage Selection: Allows selection of either 5V or 3.3V for the power supply (VCC) via switch SW1.
️· Monitorability: Provides test points for easy access to signals for debugging and analysis.
️· LED Indicators: LEDs (LED1-LED11) can be used to indicate rotation direction in a full-bridge application by manipulating SW2 switches.
️· FAULT Indicator: A low signal on the FAULT pin signifies an over-temperature or over-current condition.

3. Bill of Materials (BOM) Highlights:

This is a *very* long list, but here are some key components:

️· MPQ6526: The core motor driver IC (MPQ6526GQ-R3).
️· Power Regulation: Includes voltage regulators (MPQ2013, MPQ2013).
️· Capacitors: Multiple capacitors are used for filtering and decoupling (Murata, TDK). Note C3 is a TDK ceramic capacitor.
️· Diodes: 1N4148W diodes for various protection and signal handling purposes.
️· Fuse: CC12H4A fuse provides overcurrent protection.
️· Connectors: Wurth connectors (CN4-CN7) for load adaptation.
️· LEDs: Bright LED (BL-HUF35A-TRB) for indication.
️· Switches: SW1 to select 5V or 3.3V power and SW2 to control functions (potentially direction).
️· Test Points: Numerous test points for signal access.
