STMicroelectronics EVAL6206Q

Overview

EVAL6206Q from STMicroelectronics is a demonstration board for the L6206Q dual full-bridge motor driver IC, enabling evaluation of 2-phase stepper or up to four unidirectional DC motor control. It supports 8–52 V supply, delivers up to 2.5 A_r.m.s. per phase, features adjustable overcurrent threshold, and interfaces with STEVAL-PCC009V2 and PractiSPIN™ 2 software.

For engineers reviewing the EVAL6206Q datasheet, EVAL6206Q pinout, EVAL6206Q application, or EVAL6206Q equivalent, key considerations include its dual-bridge topology, logic-level compatibility (3.3 V/5 V), current-sensing capability via SENSEA/SENSEB outputs, and fault reporting through OCDA/OCDB signals.

Technical Context

The board implements the L6206Q's dual H-bridge architecture with independent enable (ENA/ENB) and input (IN1A/IN2A/IN1B/IN2B) control lines, supporting parallel bridge operation for higher current drive. Overcurrent detection is configurable per bridge via analog inputs (pins 11/12 on J2) and reported as open-drain logic outputs (OCDA/OCDB).

Current sensing is provided at SENSEA and SENSEB pins (J9 pins 2/3), requiring external RC filtering (R22/C12, R23/C13) for low-pass conditioning. Thermal performance is enhanced by the QFN-48 (7×7 mm) package of the underlying L6206Q, with 17 °C/W junction-to-ambient thermal resistance.

FAQ

What motor types can be controlled using the EVAL6206Q?

The EVAL6206Q supports two primary configurations: driving a single 2-phase bipolar stepper motor (full-step, half-step, microstepping with external timing), or controlling up to four independent unidirectional DC motors. Parallel bridge mode allows combined current delivery for higher-torque DC loads.

How is overcurrent protection configured on this board?

Overcurrent threshold is set independently for each bridge via analog voltage inputs (J2 pins 11 and 12). The L6206Q interprets 0–1.2 V as corresponding to ~0–2.5 A_r.m.s.; external resistive dividers or DAC outputs from a host controller adjust trip points dynamically during operation.

Does EVAL6206Q require an external controller to operate?

Yes - the board has no onboard MCU or firmware. It must be driven by an external controller (e.g., STM32 Nucleo, Arduino, or custom PCB) providing logic-level signals to J2 (IN1A/IN2A/IN1B/IN2B/ENA/ENB) and optionally reading fault outputs (OCDA/OCDB) and current sense signals (SENSEA/SENSEB).

Can EVAL6206Q be used without PractiSPIN™ 2 software?

Yes - PractiSPIN™ 2 is optional and provides GUI-based configuration and real-time monitoring. All core functionality (motor control, current sensing, fault reporting) operates with standard digital/analog I/O from any compatible host system; software is only required for automated characterization and threshold calibration.
