Monolithic Power Systems Inc. EV6514-G-00A

Overview

EV6514-G-00A from Monolithic Power Systems is an evaluation board for the MP6514 half-H-bridge motor driver IC, designed to validate dual single-ended DC motor control with independent high-side and low-side MOSFET gate drive. It supports 2.5V–14V supply, delivers up to 0.6A per channel, and integrates OCP/OVP/OTP protection. Used for rapid prototyping of low-power bidirectional motor interfaces in compact consumer devices.

For engineers reviewing the EV6514-G-00A datasheet, EV6514-G-00A pinout, EV6514-G-00A application, or EV6514-G-00A equivalent, this board enables functional validation of MP6514-based motor control logic, voltage margin testing, thermal behavior under pulsed load, and interface timing verification with microcontroller GPIOs or PWM generators.

Technical Context

The EV6514-G-00A implements a discrete half-H-bridge topology using the MP6514 QFN2×2 IC, which integrates four N-channel power MOSFETs with independent HIN/LIN control inputs per channel. It supports single-ended motor connection configurations-either motor terminal tied to VCC or GND-enabling forward/brake/coast states per channel via truth-table-driven logic.

Board-level design includes 1μF/25V and 68μF/25V ceramic input capacitors, 2.54mm DIP connectors for all I/O (HIN1/HIN2/LIN1/LIN2/OUT1/OUT2/VCC/GND), and no onboard voltage regulation-requiring external 2.5–14V DC supply. Sleep mode activates when all four input pins are held low.

FAQ

What is the primary function of the EV6514-G-00A evaluation board?

The EV6514-G-00A is a dedicated hardware platform for evaluating the MP6514 half-H-bridge motor driver IC. It provides accessible terminals for VCC, GND, HIN/LIN control signals, and OUT1/OUT2 motor outputs, enabling immediate functional testing of bidirectional DC motor control without custom PCB design.

Does the EV6514-G-00A support full H-bridge operation?

No. The EV6514-G-00A implements two independent half-H-bridges (not a full H-bridge), each driving one side of a motor winding. Motor polarity reversal requires external wiring-e.g., connecting one terminal to VCC and the other to OUT1-to achieve forward/brake/coast states per channel.

What input logic levels are required for MP6514 control on this board?

The MP6514 accepts standard TTL/CMOS logic levels: HINx and LINx inputs operate at VCC-referenced thresholds (VIH ≥ 2.0V, VIL ≤ 0.8V at VCC = 5V). No external level shifters are needed when driven by 3.3V or 5V microcontrollers.

How does the sleep mode activate on the EV6514-G-00A?

Sleep mode engages automatically when all four input pins (HIN1, HIN2, LIN1, LIN2) are held low for >100μs. In this state, internal bias circuitry powers down, reducing quiescent current to <10μA and disabling all output drivers-critical for battery longevity in idle periods.

Is the EV6514-G-00A RoHS-compliant and lead-free?

Yes. All components on the EV6514-G-00A-including the MP6514GGU IC, GRM21BR71E105KA99L capacitor, and EEU-FCIH680 electrolytic-meet RoHS Directive 2011/65/EU requirements and are halogen-free per MPS green policy.

Why is the EV6514-G-00A marked "Not Recommended for New Designs"?

MPS has superseded this board with the EV6513-J-00A, which supports the pin-compatible MP6513 IC offering improved thermal performance and tighter current-sense accuracy. While EV6514-G-00A remains functional, new designs should adopt the updated evaluation platform and associated IC.
