SPI configurable stepper and DC multi motor driver
  • active 活性

The L6460 is optimized to control and drive multi-motor system providing a unique level of integration in term of control, power and auxiliary features. Thanks to the high configurability L6460 can be customized to drive different motor architectures and to optimize the number of embedded features, such as the voltage regulators, the high precision A/D converter, the operational amplifier and the voltage comparators. The possibility to drive simultaneously stepper and DC motor makes L6460 the ideal solution for all the application featuring multi motors.
