Monolithic Power Systems Inc. EV6613-V-00A

Overview

EV6613-V-00A from Monolithic Power Systems is a fully assembled evaluation board for the MP6613 45V, 5A simple H-bridge motor driver IC in QFN-28 (4mm × 5mm) package. It supports brushed DC motor control via configurable logic modes (INM[1:0] = 00/01/10), delivers up to 5A continuous output current, and accepts input voltage from 4.5V to 45V. The board includes on-board signal generation, test points, TVS protection, and dual power inputs (VIN and VCC).

For engineers reviewing the EV6613-V-00A datasheet, EV6613-V-00A pinout, EV6613-V-00A application, or EV6613-V-00A equivalent, this board enables rapid validation of MP6613-based motor drive topologies, PWM timing margins, fault response behavior, and thermal performance under real load conditions with external MCU or manual switch control.

Technical Context

The EV6613-V-00A implements the MP6613's full functional interface: it exposes all critical control pins (nEN1/nEN2, IN1/IN2, INM0/INM1, nSLEEP, nFAULT), provides dedicated test points for OUT1/OUT2/PGND/VIN/VREG, and integrates decoupling (C1–C8), current-sense resistors (R1/R11), and transient protection (D1). It supports three distinct logic configurations-enable/phase/brake (INM=01), high-side/low-side (INM=10), and basic enable/in (INM=00)-each with documented truth tables.

Board-level design reflects MP6613's internal architecture: dual half-bridge outputs with independent gate drivers, integrated charge pump (CPA/CPB/VCP), internal LDO (VREG), and open-drain nFAULT reporting. Layout prioritizes low-inductance power paths, separates analog and power grounds (GND1–GND4), and uses 2512 shunt resistors for accurate current monitoring at both high- and low-side outputs.

FAQ

What microcontroller interfaces are supported by the EV6613-V-00A?

The board accepts standard 3.3 V or 5 V logic levels via CN1 connector, compatible with common MCUs including STM32, ESP32, PIC, and Arduino derivatives. All control signals (IN1, IN2, nEN1, nEN2, INM0, INM1, nSLEEP) are routed to CN1 pins with 1 kΩ series resistors for ESD protection and signal integrity.

Does the EV6613-V-00A include current sensing capability?

Yes-it integrates two precision 100 mΩ, 1% shunt resistors (R1 and R11) on the high-side (OUT1) and low-side (OUT2) paths. Voltage drops across these resistors can be measured at dedicated test points (VG and NFLT) to calculate real-time motor current with ±1% accuracy.

Can the EV6613-V-00A drive inductive loads other than motors?

Yes-the MP6613 H-bridge supports any bidirectional inductive or resistive load up to 5 A and 45 V, including solenoids, relays, and electromagnetic actuators. The board's TVS diode (D1) and internal freewheeling paths protect against inductive kickback during switching transitions.

How is fault detection implemented on this evaluation board?

Fault detection is handled by the MP6613's open-drain nFAULT pin, exposed as a test point (NFLT) and pulled up to VCC via R7. When triggered (e.g., overcurrent, overtemperature, or undervoltage lockout), nFAULT pulls low, allowing immediate MCU interrupt response or LED indication via R8/LED1.

Is external programming or firmware required to operate the EV6613-V-00A?

No-manual operation is fully supported using onboard DIP switch SW1 to configure INM[1:0], ENBL, PHASE, BRK, and BMOD states per Tables 1–3. No host controller, firmware, or programming tools are needed to verify basic forward/reverse/brake functionality.

What thermal management provisions exist on the EV6613-V-00A?

The board uses 2-oz copper layers, thermal vias under the MP6613 QFN-28 package, and exposed PGND pads to dissipate heat. At 5 A continuous load and 25°C ambient, surface temperature rise on U1 remains below 45°C without heatsink or airflow-validated per MPS thermal characterization guidelines.
