STMicroelectronics EVL6207-PLUG

Overview

EVL6207-PLUG from STMicroelectronics is a plug-in evaluation board designed for the L6207PD 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 2.8 A r.m.s. phase current, and features programmable OFF-time PWM current control. The board interfaces directly with the EVL62XX-MAIN baseboard and STSPIN Studio software for real-time tuning.

For engineers reviewing the EVL6207-PLUG datasheet, EVL6207-PLUG pinout, EVL6207-PLUG application, or EVL6207-PLUG equivalent, this module enables fast validation of L6207PD-based motion control designs-particularly where Arduino UNO R3 compatibility, configurable current regulation, and dual-channel H-bridge evaluation are required.

Technical Context

The EVL6207-PLUG implements the L6207PD's full functional interface-including dedicated VREFA/VREFB inputs for independent current sensing per bridge, RCA/RCB terminals for external RC timing networks controlling PWM OFF-time, and ENA/ENB enable logic synchronized with IN1A/IN2A and IN1B/IN2B step/direction inputs. It routes all critical signals (SENSEA/SENSEB, FAULTA/FAULTB, OUT1A–OUT2B) to accessible test points and headers.

Designed as a drop-in module for the EVL62XX-MAIN expansion platform, it leverages the baseboard's STM32 Nucleo-compatible header layout and Arduino UNO R3 footprint, allowing direct connection to STSPIN Studio via USB for real-time parameter adjustment, waveform capture, and fault logging without custom firmware development.

FAQ

What motor types can be evaluated with the EVL6207-PLUG?

The EVL6207-PLUG supports bipolar stepper motors (full/half-step) and two independent brushed DC motors. It uses the L6207PD's dual H-bridge architecture to drive each motor winding or channel separately, with current limiting and fault reporting enabled per bridge via SENSEA/SENSEB and FAULTA/FAULTB signals routed to test points and headers.

Does the EVL6207-PLUG require an external power supply?

Yes - the board accepts 8 V to 52 V DC input via its Vin terminal, which powers both the L6207PD driver IC and associated circuitry. It does not derive power from the EVL62XX-MAIN baseboard's logic rails; the baseboard provides only signal-level connectivity (GPIO, ADC, UART) and USB interface to STSPIN Studio.

How is PWM current control configured on this board?

PWM OFF-time is set by external RC networks connected to the RCA and RCB terminals - matching the L6207PD's internal oscillator timing. Values are selected per ST's AN4693 application note to achieve desired decay behavior (e.g., 10 kΩ + 1 nF ≈ 10 µs OFF-time). No onboard jumpers or DIP switches are used; configuration is hardware-defined.

Can the EVL6207-PLUG operate standalone without the EVL62XX-MAIN?

No - the EVL6207-PLUG lacks microcontroller, USB interface, and signal conditioning circuitry. It must be mounted on the EVL62XX-MAIN baseboard, which provides STM32-based control, STSPIN Studio communication, Arduino-compatible I/O mapping, and regulated 3.3 V/5 V logic power for the plug-in board's digital interface pins.
