Product details

Overview

EVAL6472H from STMicroelectronics is a demonstration board for the L6472 fully integrated microstepping stepper motor driver IC, supporting 8–45 V supply, 3 A_r.m.s. per phase, SPI daisy-chain configuration, and real-time parameter tuning via dSPIN software. It enables evaluation of motion control features including adjustable voltage compensation, BUSY/FLAG status monitoring, and multi-motor coordination.

For engineers reviewing the EVAL6472H datasheet, EVAL6472H pinout, EVAL6472H application, or EVAL6472H equivalent, this board serves as a validated hardware platform to configure, debug, and validate L6472-based stepper systems-especially in precision positioning, closed-loop motion prototyping, and industrial automation subsystem development.

Technical Context

The EVAL6472H implements the L6472 H-bridge driver in HTSSOP28 package with integrated current regulation, adaptive decay control, and non-dissipative overcurrent protection. It interfaces directly with the STEVAL-PCC009V2 communication board via master/slave SPI connectors (J10/J11), enabling synchronized multi-axis evaluation.

Board-level design includes dual test point arrays (TP1–TP11), jumper-configurable VDD/VREG sourcing (JP1/JP2), daisy-chain termination (JP3), and ADCIN-based supply voltage compensation. Thermal resistance is 21 °C/W (junction-to-ambient), validated under continuous 3 A_r.m.s. operation at +25 °C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply voltage (VS)	8–45 V DC input range - supports wide-range industrial power rails and battery-backed motion systems.
Max output current	3 A_r.m.s. per phase - enables driving NEMA 17–23 stepper motors at full microstepping resolution.
Logic interface voltage	3.3 V or 5 V externally supplied - ensures compatibility with both modern low-voltage MCUs and legacy 5 V controllers.
SPI daisy chain	Supported via JP3 and J10/J11 connectors - allows cascading multiple EVAL6472H boards for synchronized multi-motor control without additional MCU GPIOs.
Operating temperature	−25 to +125 °C - validated for use in enclosed industrial enclosures and thermally demanding environments.
Thermal resistance	21 °C/W junction-to-ambient - confirms stable thermal performance without forced airflow under rated load.

FAQ

What is the role of the STEVAL-PCC009V2 when used with EVAL6472H?

The STEVAL-PCC009V2 is a USB-to-SPI communication board that bridges a host PC to the EVAL6472H via the master SPI connector (J10). It enables real-time parameter configuration, motion command execution, and status monitoring through ST's dSPIN evaluation software-without requiring custom firmware or MCU programming.

Can EVAL6472H drive bipolar stepper motors without external components?

Yes. The EVAL6472H integrates the L6472 IC, which contains dual H-bridges, current sensing, PWM control logic, and adaptive decay circuitry. No external gate drivers, current sense resistors, or decay control components are needed to operate standard 2-phase bipolar stepper motors up to 3 A_r.m.s..

How does the ADCIN input function on EVAL6472H?

The ADCIN input (connected to TP7) monitors motor supply voltage (VS) and feeds it into the L6472's internal ADC to dynamically adjust PWM duty cycle and current regulation thresholds. This compensates for line drops or battery sag during acceleration, maintaining consistent torque across varying input conditions.

Is daisy-chaining supported between multiple EVAL6472H boards?

Yes. Daisy-chaining is enabled by configuring JP3 (termination jumper) and using J10 (master out) and J11 (slave in) connectors. Each board shares the same SPI clock and CS lines while routing SDO→SDI between adjacent units-allowing coordinated motion control of up to eight axes with one MCU SPI interface.
