This document is an application note about L6460 SPI configurable stepper and DC multi motor driver.
The document introduces the L6460, an integrated chip optimized for controlling multi-motor systems by driving both stepper and DC motors simultaneously. It highlights features such as high configurability via a slave SPI interface, embedded voltage regulators, precision A-D converters, and operational amplifiers.
The guide details the EVAL6460 demonstration board, which showcases the L6460's capabilities with two DC motors and one stepper motor. It provides instructions on configuring jumpers, connecting loads, using the FlexSPIN evaluation software, and programming the device via SPI to control various functions like PWM generation, GPIO assignment, and thermal monitoring.
| Max. operative current (Bridges 1 & 2) | 2.5 A |
|---|---|
| Max. operative current (Bridges 3 & 4) | 1.5 A |
