SPI configurable stepper and DC multi motor driver

■

Operating supply voltage from 13 V to 38 V

■

4 full bridge driver configurable in multi-motor 
application to drive:

– 2 DC and 1 stepper motor 

– 4  DC  motor

■

Bridge 1 and 2 (R

DSon

 = 0.60 

Ω) can be 

configured to work as:

– Dual full bridge driver

– Super DC driver

– 2 half bridge driver

– 1 super half bridge

– 1 super power switch

■

Bridge 3 and 4 (R

DSon

 = 0.85 

Ω) can be 

configured to work as:

– Same as bridges 1 and 2, listed above

– Stepper motor driver: up to 1/16 

microstepping

– 2 buck regulators (bridge 3)

– 1 super buck regulator

■

Integrated power sequencing and supervisory 
functions with fault signaling through serial 
interface and external reset pin

■

Very low power dissipation in shut-down mode 
(~35 mW)

■

Auxiliary features

– Multi-channels 9 bit ADC
– 2 operational amplifiers
– Digital comparator

– 2 low voltage power switches

– 3 general purpose PWM generators

– 14  GPIOs

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.
