STMicroelectronics EVL6226-PLUG

Overview

EVL6226-PLUG from STMicroelectronics is a plug-in evaluation board designed for the L6226PD dual H-bridge motor driver IC, enabling rapid prototyping of bipolar stepper and dual brushed 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 high-side overcurrent protection and Arduino UNO R3 connector compatibility.

For engineers reviewing the EVL6226-PLUG datasheet, EVL6226-PLUG pinout, EVL6226-PLUG application, or EVL6226-PLUG equivalent, this board serves as a validated hardware interface for evaluating L6226PD-based motion control in embedded industrial actuators, lab automation stages, and precision positioning subsystems.

Technical Context

The EVL6226-PLUG implements direct hardware interfacing between the STM32 Nucleo host (via EVL62XX-MAIN baseboard) and the L6226PD driver IC, exposing all critical control signals including PROGCLA/PROGCLB for overcurrent threshold tuning, ENA/ENB for channel enable, and IN1A/IN2A/IN1B/IN2B for step/direction or PWM logic inputs.

It routes analog sense paths (SENSEA/SENSEB), fault outputs (FAULTA/FAULTB), and VREFA/VREFB reference inputs to accessible test points and headers, supporting real-time current regulation validation and closed-loop current feedback calibration per motor winding.

FAQ

Is EVL6226-PLUG a standalone evaluation board?

No. The EVL6226-PLUG is a plug-in module that requires the EVL62XX-MAIN baseboard to function. It lacks onboard MCU, USB interface, or power regulation - those are provided by the MAIN board. Without it, no control signals or power routing is possible.

What motor driver IC does EVL6226-PLUG evaluate?

EVL6226-PLUG evaluates the L6226PD - a dual H-bridge monolithic driver in PowerSO-36 package, rated for 52 V max supply and 1.4 A r.m.s. output current per channel, with integrated high-side current sensing and programmable overcurrent protection.

Can EVL6226-PLUG be used with other L62xx plug-in boards?

Yes - all EVL62XX-PLUG variants (EVL6205–EVL6228) share identical mechanical and electrical footprint on the EVL62XX-MAIN board. They are mechanically and electrically interchangeable, allowing quick comparison of L6226PD against L6206PD, L6227PD, etc., using the same baseboard and software stack.

Does EVL6226-PLUG support microstepping?

No - the L6226PD IC itself does not implement microstepping logic. It operates in full-step or half-step modes controlled externally by the host MCU (e.g., STM32 on EVL62XX-MAIN). Microstepping requires external pulse interpolation; the board provides only the power stage interface.
