Description
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.
