Product details
Overview
EVL6227-PLUG from STMicroelectronics is a plug-in evaluation board designed for the L6227 dual H-bridge motor driver IC, enabling rapid prototyping of bipolar stepper and dual brush DC motor control systems. It supports 8 V to 52 V supply voltage, delivers up to 1.4 A r.m.s. phase current, and features programmable OFF-time PWM current control. The board integrates seamlessly with the EVL62XX-MAIN baseboard and STSPIN Studio software for real-time tuning and validation in lab and development environments.
For engineers reviewing the EVL6227-PLUG datasheet, EVL6227-PLUG pinout, EVL6227-PLUG application, or EVL6227-PLUG equivalent, this module provides direct access to L6227PD's full functional interface-including VREFA/VREFB analog reference inputs, RCA/RCB current sense timing controls, ENA/ENB enable logic, and IN1A/IN2A/IN1B/IN2B step/direction and half/full-step configuration-enabling precise current regulation, fault monitoring (FAULTA/FAULTB), and motor phase sequencing verification.
Technical Context
The EVL6227-PLUG implements the L6227PD's internal PWM chopper architecture with externally adjustable OFF-time via RCA and RCB resistors, allowing fine-grained control over decay mode and average current. It routes all critical analog (VREFA, VREFB, SENSEA, SENSEB) and digital (ENA, ENB, IN1A–IN2B, RESET) signals to accessible test points and headers for oscilloscope probing and MCU-level integration.
Designed as a drop-in replacement within the EVL62XX-PLUG family, it maintains mechanical and electrical compatibility with the EVL62XX-MAIN expansion board and Arduino UNO R3 connector footprint, supporting shared firmware abstraction layers and unified STSPIN Studio configuration across L62xx driver variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Voltage range | 8 V to 52 V input - powers L6227PD directly without external DC-DC conversion; supports industrial 24 V and higher-voltage stepper systems. |
| Phase current | Up to 1.4 A r.m.s. - matches L6227PD's rated output capability; enables driving NEMA 17–23 stepper motors or dual 12 V/24 V brushed DC actuators. |
| PWM OFF-time control | Programmable via RCA/RCB resistors - sets chopper frequency and decay behavior; determines torque smoothness and thermal performance under load. |
| Interface compatibility | Arduino UNO R3 pinout - allows direct connection to STM32 Nucleo boards and standard development platforms without adapter hardware. |
| Current sensing | Dual SENSEA/SENSEB outputs - provide real-time analog feedback proportional to motor phase current; used for closed-loop current limiting and stall detection. |
| Fault signaling | FAULTA/FAULTB open-drain outputs - assert low on overcurrent, overtemperature, or undervoltage; enable immediate system shutdown or graceful deceleration. |

FAQ
What motor types does the EVL6227-PLUG support?
The EVL6227-PLUG supports bipolar stepper motors and dual independent brushed DC motors via the L6227PD driver IC. It handles full- and half-step excitation modes using IN1A/IN2A and IN1B/IN2B logic inputs, and delivers up to 1.4 A r.m.s. per phase with integrated current sensing and thermal protection.
How is PWM current control configured on this board?
PWM current control is configured using external resistors RCA and RCB connected to pins 12 and 25 of the L6227PD, which set the chopper OFF-time. Values determine decay mode (fast/slow/mixed) and effective current regulation frequency; typical values are 2.2 kΩ (RCA) and 2.2 kΩ (RCB) as shown in Figure 8 of DB4485 Rev 1.
Can EVL6227-PLUG operate standalone without EVL62XX-MAIN?
No. The EVL6227-PLUG is a plug-in daughterboard requiring the EVL62XX-MAIN baseboard for power distribution, microcontroller interface (e.g., STM32 Nucleo), and signal routing. It lacks onboard regulation, USB interface, or processing capability and is not functional when disconnected from the MAIN board.
Which software tools are compatible with this evaluation board?
EVL6227-PLUG is fully supported by ST's STSPIN Studio GUI, which enables real-time parameter tuning (VREF, OFF-time, decay mode), waveform capture, fault logging, and motor profile generation. It also works with STM32CubeMX and HAL libraries when used with compatible Nucleo boards and custom firmware.
