STMicroelectronics EVAL6460

Overview

EVAL6460 from STMicroelectronics is an evaluation board for the L6460 SPI-configurable multi-motor driver IC, designed to validate stepper + DC motor control architectures in embedded motion systems. It supports dual full-bridge (R_DS(on) = 0.60 Ω), stepper microstepping up to 1/16, integrated buck regulators, battery charging, and 9-bit ADC monitoring - enabling rapid prototyping of industrial actuators, robotic joints, and automated medical devices.

For engineers reviewing the EVAL6460 datasheet, EVAL6460 pinout, EVAL6460 application, or EVAL6460 equivalent, this board provides verified hardware reference for L6460 register configuration, power sequencing, thermal fault response, and mixed-signal motor control validation under real load conditions.

Technical Context

The EVAL6460 implements the full L6460 feature set: four configurable H-bridges (Bridges 1–4), dual independent switching regulators (one main buck, one controller), linear V3V3 regulator, battery charger circuit on Bridge 4, and supervisory functions including thermal warning, overcurrent detection, and programmable watchdog timeout.

It enables simultaneous operation modes - e.g., Bridges 1 & 2 as super DC drivers while Bridges 3 & 4 run stepper microstepping with synchronous buck regulation - all coordinated via SPI register writes and validated through on-board GPIOs, op-amps, and ADC channels for closed-loop tuning.

FAQ

What is the primary purpose of the EVAL6460?

The EVAL6460 is a fully assembled and tested evaluation board for the L6460 motor driver IC. It provides immediate hardware access to all L6460 features - including bridge configuration, regulator setup, ADC monitoring, and SPI register control - allowing engineers to validate motor control algorithms, power architecture, and fault-handling behavior without custom PCB design.

Does EVAL6460 support stepper motor microstepping?

Yes. The board enables full 1/16 microstepping operation using Bridges 3 and 4 configured as a bipolar stepper driver, with adjustable off-time and fast-decay control via SPI registers. On-board jumpers and test points allow direct measurement of phase currents and step timing accuracy under load.

Can EVAL6460 be used to evaluate battery charging functionality?

Yes. Bridge 4 is preconfigured to operate as a battery charger regulator, supporting constant-current/constant-voltage profiles. The board includes dedicated sense resistors, feedback dividers, and thermal monitoring to verify charge cycle behavior, termination logic, and safety cutoffs per L6460 specification.

Is firmware or software provided with EVAL6460?

ST provides the X-CUBE-MCSDK (Motor Control SDK) with dedicated L6460 drivers, GUI-based configuration tools, and example projects for STM32 host MCUs. The EVAL6460 interfaces directly via SPI and supports register-level debugging, real-time parameter tuning, and fault injection testing through its onboard debug headers.
