EV6500A-U-00A

EV6500A-U-00A 35V, 2.5A, Bipolar Stepper Motor Driver with Current Setting via VSET in QFN-24 Package Evaluation Board DESCRIPTION The EV6500A-U-00A is an evaluation board designed to demonstrate the capabilities of the MP6500A, a stepper motor driver with a built-in, microstepping translator. by setting the MS2 and MS1 pins. The input control signals for the MP6500A are applied through the connector or generated on the board. The MP6500A 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 The MP6500A is available in a QFN-24 (5mmx5mm) package. It is recommended to read the MP6500A datasheet prior to making any changes to the EV6500A-U-00A. PERFORMANCE SUMMARY Parameters Input voltage (VIN) range Maximum output current (IOUT_MAX) VCC voltage (VCC) Conditions Value 4.5V to 35V 2.5A 3.3V or 5V EV6500A-U-00A EVALUATION BOARD LxW (6.35cmx6.35cm) Board Number MPS IC Number EV6500A-U-00A MP6500AGU EV6500A-U-00A Rev. 1.0 MonolithicPower.com 5/12/2022 MPS Proprietary Information.

Connect the input voltage (4.5V ≤ VIN ≤ 35V) and input ground to the VIN and GND connectors, respectively. 2. To configure the output current limit (IOUT_LIM) via the VSET pin, follow the steps below: a. Remove the JP1 jumper and connect an external 0V to 2V voltage to the VSET connector. b. Add the JP1 jumper and manually adjust RV1. Manual action requires an external 3.3V or 5V VCC voltage (VCC) as a pull-up power supply. 3. Switch SW2 to the top side (Terminal 3 in Figure 1 on page 3) to enable the external step signal input from the EXT_STEP connector. 4. Connect the step signal to the EXT_STEP connector. 5. Set the input control and logic signal through the CN1 connector via the external MCU, or manually through SW1. Manual action requires an external 3.3V or 5V VCC as a pull-up power supply.
