STMicroelectronics EVL6228-PLUG

Overview

EVL6228-PLUG from STMicroelectronics is a plug-in evaluation board designed for the L6228 dual H-bridge motor driver IC, enabling rapid prototyping of bipolar stepper and dual brushed DC motor control systems. It supports 8–52 V input voltage, delivers up to 1.4 A r.m.s. phase current, features programmable PWM OFF-time control, and mounts directly onto the EVL62XX-MAIN baseboard compatible with Arduino UNO R3 headers.

For engineers reviewing the EVL6228-PLUG datasheet, EVL6228-PLUG pinout, EVL6228-PLUG application, or EVL6228-PLUG equivalent, this board serves as a validated hardware interface for evaluating L6228-based motion control in industrial actuators, lab automation stages, and precision positioning subsystems requiring configurable current regulation and half/full-step mode selection.

Technical Context

The EVL6228-PLUG implements the L6228PD motor driver IC in a compact plug-in form factor, interfacing via 40-pin male headers (BTE-020-01-F-D-A-TR) to the EVL62XX-MAIN carrier. It routes all critical control signals-including CLOCK, CW/CCW, HALF/FULL, CONTROL, RESET, and EN-alongside VREFA/VREFB analog reference inputs and RCA/RCB external RC networks for PWM timing configuration.

Designed for direct integration with STM32 Nucleo-based evaluation environments and STSPIN Studio software, the board exposes SENSEA/SENSEB current-sense outputs, FAULTA/FAULTB status lines, and OUT1A/OUT1B/OUT2A/OUT2B power-stage terminals, supporting both microstepping-ready bipolar stepper and independent dual brushed DC motor topologies under single-supply operation.

FAQ

Is EVL6228-PLUG compatible with STM32 Nucleo boards?

Yes. The EVL6228-PLUG is designed to mount directly onto the EVL62XX-MAIN baseboard, which features native compatibility with STM32 Nucleo development platforms via standardized Arduino UNO R3 headers and STSPIN Studio software support for parameter configuration and real-time waveform analysis.

What motor types can be evaluated using EVL6228-PLUG?

EVL6228-PLUG supports bipolar stepper motors (in half-step or full-step mode) and two independent brushed DC motors. Its L6228PD driver provides dual H-bridge outputs with current sensing, fault reporting, and programmable PWM decay, making it suitable for open-loop positioning and bidirectional DC actuation.

Does EVL6228-PLUG require an external power supply?

Yes. The board accepts an 8–52 V DC input via its VIN terminal, separate from the host MCU's 5 V logic supply. This allows independent scaling of motor bus voltage while maintaining safe logic-level signaling through level-shifted control interfaces and optocoupled or resistor-limited signal paths.

Can EVL6228-PLUG be used without the EVL62XX-MAIN baseboard?

No. EVL6228-PLUG is a plug-in module intended exclusively for use with the EVL62XX-MAIN carrier board. It lacks onboard regulation, USB interface, MCU, or debug circuitry - all control, power distribution, and host connectivity functions are provided by the MAIN board.
