This document provides detailed information about the EVAL6470PD motor driver, including voltage range, phase current, SPI connector, SW input, FLAG and BUSY LED indicators, adjustable supply voltage compensation, and high thermal performance
The EVAL6470PD is a demonstration board designed to evaluate the features of the L6470 microstepping motor driver. It utilizes a high-power PowerSO package and a 4-layer layout to achieve top thermal performance with a typical junction-to-ambient thermal resistance of 12 °C/W.
The board supports a supply voltage range from 8 V to 45 V and can deliver up to 3 Arms per phase. It includes dual SPI connectors for daisy-chain configurations, making it suitable for multi-motor applications. The board is intended to be used in combination with the STEVAL-PCCO09V2 communication board.
