Monolithic Power Systems Inc. EV6513-J-00A

Overview

EV6513-J-00A from Monolithic Power Systems is an evaluation board for the MP6513GJ full-H-bridge motor driver IC, designed to validate bidirectional DC motor or unipolar stepper winding control. It supports 2.5V–21V input voltage, delivers up to 0.8A per channel, and features integrated OCP/OVP/OTP protection. Used with two independent MP6513GJ ICs (U1 & U2), it enables dual-channel motor evaluation in compact consumer motion systems.

For engineers reviewing the EV6513-J-00A datasheet, EV6513-J-00A pinout, EV6513-J-00A application, or EV6513-J-00A equivalent, this board provides verified layout, test-point access to AIN1/AIN2/BIN1/BIN2 control inputs and AOUT1/AOUT2/BOUT1/BOUT2 motor outputs, plus factory-configured 2.5–21V operation and dual-channel truth-table logic validation.

Technical Context

The EV6513-J-00A implements two independent MP6513GJ H-bridge drivers on a single PCB, each configured with dedicated 2-pin input (AIN1/AIN2, BIN1/BIN2), 2-pin output (AOUT1/AOUT2, BOUT1/BOUT2), and shared VCC/GND rails. Control logic follows standard PWM-driven truth table: IN1/IN2 combinations determine forward, reverse, brake, or coast states.

Board-level design includes 1µF/25V ceramic (C1/C2), 68µF/25V electrolytic (C3), and four 100pF C0G decoupling caps (C4–C7), plus 49.9Ω current-sense resistors (R1–R4) and 2× FCTSOT-23-6 packaged MP6513GJ ICs. All connectors use 2.54mm pitch SIP headers for signal routing and motor termination.

FAQ

What motors can be driven using the EV6513-J-00A?

The board supports one bipolar stepper motor (using both channels) or two independent DC motors (one per channel). Each channel drives loads up to 0.8A at 2.5–21V, including small PMDC motors and unipolar stepper windings. Motor leads connect directly to CN2 (AOUT) and CN3 (BOUT) terminals.

How are the input control signals applied?

Logic-level PWM or digital signals are applied via 2.54mm-pitch SIP headers: AINPUT (pins AIN1/AIN2) controls U1, BINPUT (pins BIN1/BIN2) controls U2. Truth table mapping (L/L = coast, H/L = forward, etc.) is implemented directly by the MP6513GJ ICs without external logic.

Does the board include current sensing or feedback?

No. The EV6513-J-00A does not integrate current sensing or closed-loop feedback circuitry. It provides only drive output and control input access. External current monitoring requires adding shunt resistors or Hall sensors at AOUT1/AOUT2 or BOUT1/BOUT2 nodes.

Can the board operate from a 3.3V or 5V supply?

Yes. The 2.5–21V input range includes common logic-supply voltages. At 3.3V or 5V, the MP6513GJ maintains full functionality with reduced maximum motor current due to lower headroom - verified in MPS application notes for low-voltage operation.

Is thermal management provided on the board?

The board uses exposed pad FCTSOT-23-6 packages for U1/U2 and includes copper pour on both layers per MPS layout guidelines. No heatsink or fan is included; continuous 0.8A operation requires ambient ≤50°C and adequate airflow or board-level thermal relief.

Are schematics and layout files available?

Yes. The official schematic (Figure 1), top/bottom PCB layer drawings (Figures 2–3), and BOM are published in the Rev. 1.0 user guide (MPS document EV6513-J-00A-UG). These files are accessible via the Monolithic Power Systems website under the EV6513-J-00A product page.
