This document describes the features and characteristics of a product called L6470. The product is a fully integrated stepper motor driver with a voltage range from 8V to 45V and a phase current up to 3Arms. It supports SPI with daisy-chain feature and has a socket for external resonator or crystal. It is suitable to be used in combination with STEVAL-PCC009V2. The product also has adjustable supply voltage compensation and is suitable for the evaluation of multi-motor applications.
The EVAL6470H is a fully integrated microstepping motor driver demonstration board designed for use with the L6470 device. It supports voltage mode driving and allows users to regulate L6470 parameters to fit specific application requirements. When combined with the STEVAL-PCC009V2 communication board and dSPIN evaluation software, the board enables investigation of all L6470 features.
