DESCRIPTION
The EV6500-U-00A is a n evaluation board for the MP6500GU, a stepper motor driver with a built-in microstepping translator. The MP6500 operates from a supply voltage of up to 35V, and can deliver a motor current up to 2.5A. It can operate a bipolar stepper motor in full- half-, quarter -, and eighth-step modes by setting the MS2 and MS1. The input control signals for the MP 6500 are applied through the connector, or generated on the board. ELECTRICAL SPECIFICATIONS Parameter Symbol Value Units Input voltage VIN 4.5 to 35 V Maximum output current IOUT-L 2.5 A Decay mode Automatic decay
FEATURES
Wide 4.5V to 35V Input Voltage Range Up to 2.5A Configurable Output Current Full, Half-, Quarter-, and Eighth-Step Modes Automatic Decay Mode OCP, OVP, OTP Fault Indication Output

EV6500-U-00A – 2.5A, 35V, BIPOLAR STEPPER MOTOR DRIVER EVAL BOARD EV6500-U-00A Rev. 1.1 www.MonolithicPower.com 2 7/16/2020 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2020 MPS. All Rights Reserved. QUICK START GUIDE 1. Attach the input voltage (4.5V ≤ VIN ≤ 35V) to the VIN connector, and attach the input ground to the GND connector. 2. To enable the external step signal input from the EXT_STEP connector , switch SW2 to position 3 (top side). 3. Attach the step signal to the EXT_STEP connector. 4. The input control and logic signal can be set through the CN1 connector, the external MCU, or through SW1 via manual action. Manual action requires an external, 5V VCC voltage to be used as a pull-up power supply.
