Monolithic Power Systems Inc. EV6513L-J-00A

Overview

EV6513L-J-00A from Monolithic Power Systems is an evaluation board for the MP6513LGJ full-H-bridge motor driver IC, designed to drive reversible DC motors or single windings of bipolar stepper motors. It supports 2.5V–5.5V supply voltage, delivers up to 0.6A continuous output current per channel, and features integrated over-current, over-voltage, and over-temperature protection. Used in compact motion control prototyping for consumer and medical devices.

For engineers reviewing the EV6513L-J-00A datasheet, EV6513L-J-00A pinout, EV6513L-J-00A application, or EV6513L-J-00A equivalent, this board enables rapid validation of MP6513LGJ's dual-channel H-bridge operation, PWM-controlled bidirectional drive, thermal shutdown behavior, and logic-level input compatibility with microcontrollers in low-voltage embedded systems.

Technical Context

The EV6513L-J-00A implements two independent MP6513LGJ ICs (U1 and U2), each configured as a standalone full-H-bridge with separate IN1/IN2 control inputs and OUT1/OUT2 motor outputs. Each channel operates from 2.5V to 5.5V and sustains 0.6A continuous current with internal current limiting and thermal foldback.

Input logic follows standard truth-table control: IN1=H/IN2=L drives forward; IN1=L/IN2=H drives reverse; both high applies brake; both low enables coast. The board provides dedicated AINPUT/BINPUT headers for logic signals and AOUT/BOUT screw terminals for motor connections, with decoupling (1µF + 68µF) and RC snubbers (50Ω + 100pF) per channel.

FAQ

What motor types can be controlled using the EV6513L-J-00A?

The board supports one reversible DC motor or one winding of a bipolar stepper motor per channel. It is not intended for brushed DC motors requiring >0.6A peak current or unipolar stepper configurations. Dual-channel operation allows independent control of two DC motors or coordinated two-phase stepping via external logic sequencing.

Does the EV6513L-J-00A include on-board voltage regulation?

No. The board accepts raw 2.5V–5.5V input directly at the VCC/GND pins on CN1. There is no LDO or DC/DC converter onboard - users must provide a clean, regulated supply matching the MP6513LGJ's operating range and current capability.

How are the input control signals connected?

Logic-level signals are applied via the AINPUT (pins AIN1, AIN2, GND) and BINPUT (pins BIN1, BIN2, GND) 3-pin headers. Each pair corresponds to one MP6513LGJ channel. Signals must be 0V/3.3V or 0V/5V compatible - no level-shifting circuitry is included.

Can the EV6513L-J-00A drive a 4-wire bipolar stepper motor?

Yes - connect one phase winding between AOUT1/AOUT2 and the other between BOUT1/BOUT2. Microcontroller-generated complementary PWM pairs must be supplied to AINPUT and BINPUT to achieve full-step or half-step excitation; the board itself does not generate stepping waveforms.

What protection mechanisms are implemented on the board?

Each MP6513LGJ IC provides internal over-current protection (OCP), over-voltage protection (OVP), and over-temperature protection (OTP). These functions are active by default and do not require external configuration - fault conditions trigger automatic output disable and recovery after thermal/current reset thresholds are met.

Is there a recommended input signal slew rate for reliable operation?

MP6513LGJ specifies a maximum input rise/fall time of 1 µs. The board's 50Ω series resistors (R1–R4) and 100pF capacitors (C4–C7) form RC filters that limit edge rates and suppress noise coupling - ensuring robust switching under typical MCU GPIO drive conditions without unintended transitions.
