STMicroelectronics EVAL6206N

Overview

EVAL6207N from STMicroelectronics is a motor control evaluation board designed to interface with the ST Industrial Communication Board (EVALCOMMBOARD) for closed-loop stepper and DC motor testing. It provides dual-channel PWM current control reference inputs (VREFA/VREFB), real-time sense feedback (SENSE_A/SENSE_B), overcurrent protection flags (LIMIT_A/LIMIT_B), and gate drive enable signals (ENA/ENB). It supports micro-stepping via analog reference voltage synthesis and is used with ST's AD5317 DAC-based control platform.

For engineers reviewing the EVAL6207N datasheet, EVAL6207N pinout, EVAL6207N application, or EVAL6207N equivalent, this board serves as a verified hardware interface for validating motor driver ICs-including L6206, L6207, and L6229-within ST's industrial communication ecosystem, enabling rapid firmware-driven torque and position profiling.

Technical Context

The EVAL6207N is a passive daughterboard that receives analog reference voltages (VREFA/VREFB) from the host EVALCOMMBOARD's DAC outputs and operational amplifiers, then conditions them for use by motor driver ICs. It routes sense signals (SENSE_A/SENSE_B) back to the host for current monitoring and delivers logic-level enable (ENA/ENB) and fault flag (LIMIT_A/LIMIT_B) signals between MCU and power stage.

It implements no active circuitry or embedded intelligence-its function is strictly signal translation, level adaptation, and connector standardization. All timing, PWM generation, and control logic reside on the EVALCOMMBOARD microcontroller (ST72F651AR6) and are delivered to the EVAL6207N via fixed-function analog and digital I/O pins defined in Table 2 of UM0240.

FAQ

Is EVAL6207N a standalone motor driver board?

No. EVAL6207N contains no power switches, gate drivers, or control logic. It is a passive interface board that must be used with the ST Industrial Communication Board (EVALCOMMBOARD) to provide analog reference voltages, sense routing, and logic-level signaling to external motor driver ICs like L6206 or L6229.

What firmware or software is required to operate EVAL6207N?

EVAL6207N requires the EVALCOMMBOARD firmware (v1.x or later) and ST's dedicated GUI software-specifically the "Stepper Motor GUI" or "DC Motor Driving GUI" described in UM0240 Sections 11.2 and 17–18. No firmware resides on EVAL6207N itself.

Can EVAL6207N be used with non-ST motor drivers?

Only if pinout, voltage levels, and signal timing match the interface definition in UM0240 Table 2. The board's 34-pin J7 connector is designed specifically for ST's L6206/L6207/L6229 family; deviations in enable polarity, fault flag behavior, or sense input impedance may cause interoperability issues.

Does EVAL6207N include current sensing or protection circuitry?

No. It routes SENSE_A/SENSE_B signals from the motor driver IC to the EVALCOMMBOARD for ADC sampling but adds no amplification, filtering, or overcurrent shutdown logic. Protection relies entirely on the connected driver IC (e.g., L6207's internal thermal/current foldback) and host firmware response.
