2 EVAL6460 board description
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.
Tabl e 1 summarizes the operating rating specification of the application, Ta bl e 2 lists the
connectors and jumpers available on the board and their function; Figure 2 shows the
electrical schematic and Ta bl e 3 shows the BOM list.
