GPIO pins
Some of the pins of L6460 are indicated as GPIO (General purpose I/O). These pins can be
configured to be used in different ways depending on customer application. All GPIOs can
be used as digital input/output pins with digital value settable/readable using serial interface
or as analog input pins that can be converted using the A2D system. Some of the pins can
be used for special purposes: i.e. two of them can be used to access to the pass switch
function, other two are used as feedback pins for the auxiliary synchronous switching
regulators.
All input Schmitt triggers and output circuitry used for start-up purposes are powered by the
internally generated V
ensure independency between V
driver or the high side MOS is in back-to-back configuration to avoid the presence of the
body diode between output and supply.
All digital output signals can be inverted before being provided on the relative GPIO pins.
Here below is reported the table with GPIO functions.
