摘要：本方案采用了L6460优化控制和驱动多电机系统，向开发者提供了一个独特的控制系统，包括电源等辅助功能设备。
基本特性：
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.
方案描述：
the 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 of simultaneously driving the stepper and DC motors makes the L6460 the ideal solution for all applications featuring multi motors.The L6460 can communicate with an external microprocessor by using an integrated slave  SPI (serial protocol interface); through this interface the majority of the L6460’s functions can be controlled.Master device interfacing with multiple SPI slave devices has an nSS signal to address each slave device.
This demonstration board shows an example of an application which the L6460 is able to manage:
2 DC motors
1 stepper motor
3 power supplies: 1.2 V, 3.3 V and 12 V.
