Monolithic Power Systems Inc. EV6612D-F-00A

Overview

EV6612D-F-00A from Monolithic Power Systems is an evaluation board for the MP6612D 40V, 5A H-bridge DC motor driver IC, supporting reversible motor control via DIR/ENBL logic interface and integrated current sensing (VISEN output). It operates from 4V–40V input, delivers up to 5A continuous motor current, and features TSSOP-20EP-mounted MP6612DGF with exposed thermal pad for thermal management in compact motor drive applications.

For engineers reviewing the EV6612D-F-00A datasheet, EV6612D-F-00A pinout, EV6612D-F-00A application, or EV6612D-F-00A equivalent, this board enables rapid validation of MP6612D's forward/reverse/brake operation, real-time current monitoring via adjustable VISEN scaling, and manual or MCU-driven DIR/ENBL control - critical for robotics, actuator prototyping, and industrial motion subsystem development.

Technical Context

The EV6612D-F-00A implements the MP6612D's dual N-channel MOSFET H-bridge topology with integrated gate drivers, low-side current sense amplifier, and fault reporting (nFAULT). Control logic accepts 3.3V/5V-compatible DIR and ENBL signals, while nSLEEP enables power-down mode with <10µA quiescent current.

Current sensing is implemented through the ISET pin and external resistor network (RV1 + R1), scaling motor current to a 0–1.5V VISEN output linearly per Equation (1); the board supports direct oscilloscope probing at dedicated 1mm test points for VISEN, FLT, VCP, and ISET.

FAQ

What input voltage range does the EV6612D-F-00A support?

The board accepts 4V to 40V DC input at the VIN connector, directly matching the MP6612D's specified operating range. This allows validation across common motor supply rails including 12V automotive, 24V industrial, and 36V e-mobility systems. Input polarity protection is not integrated; correct connection must be verified before power-up.

How is motor current measured on this evaluation board?

Motor current is sensed via the MP6612D's internal low-side FET current mirror and output as a voltage (VISEN) scaled by external resistors RV1 and R1. With RV1 set to 10kΩ and R1 at 4.99kΩ, full-scale 5A maps to 1.5V at the VISEN test point, enabling direct ADC sampling or oscilloscope monitoring without signal conditioning.

Can the EV6612D-F-00A drive brushed DC motors in both directions?

Yes - direction is controlled by the DIR pin state while ENBL is high: DIR = low enables reverse (OUT1 low, OUT2 high), DIR = high enables forward (OUT1 high, OUT2 low). When ENBL = low, both outputs are forced low for active braking. Truth table behavior is confirmed in Table 1 of the board's Rev. 1.1 documentation.

Does the board include thermal management features for 5A operation?

Yes - the MP6612DGF is mounted in TSSOP-20EP with its exposed thermal pad soldered to a large internal copper plane and multiple thermal vias connecting to bottom-layer ground pour. The board layout follows MPS' recommended thermal design guidelines, enabling sustained 5A operation at TA = 25°C with minimal heatsinking.

What interfaces are provided for connecting an external microcontroller?

A 10-pin 2.54mm pitch header (CN1) provides access to DIR, ENBL, nSLEEP, nFAULT, VISEN, ISET, V3P3, GND, GND1, and FLT signals. All logic-level signals are 3.3V/5V compatible, and pull-up resistors are pre-installed for DIR/ENBL/nSLEEP, allowing direct connection to most MCU GPIOs without level-shifting.

Is there onboard manual control capability without an MCU?

Yes - SW1 is a 3-position slide switch that manually sets DIR and ENBL states (Forward, Reverse, Brake), with external 3.3V or 5V required as pull-up supply. This enables immediate functional verification before firmware integration, using only a bench power supply and multimeter or oscilloscope.
