VXn PINS AS DIGITAL INPUTS
As mentioned in the Supply Supervision with VX
section, the VXn input pins on the ADM1069 have dual
functionality. The second function is as a digital input to the
device. Therefore, the ADM1069 can be configured for up to
four digital inputs. These inputs are TTL-/CMOS-compatible.
Standard logic signals can be applied to the pins: RESET from
reset generators, PWRGD signals, fault flags, manual resets, and
more. These signals are available as inputs to the SE, and therefore,
can be used to control the status of the PDOs. The inputs can be
configured to detect either a change in level or an edge.
When configured for level detection, the output of the digital
block is a buffered version of the input. When configured for
edge detection, once the logic transition is detected, a pulse of
programmable width is output from the digital block. The
width is programmable from 0 μs to 100 μs.
The digital blocks feature the same glitch filter function that is
available on the SFDs. This enables the user to ignore spurious
transitions on the inputs. For example, the filter can be used to
debounce a manual reset switch.
When configured as digital inputs, each VXn pin has a weak
(10 μA) pull-down current source available for placing the input
in a known condition, even if left floating. The current source, if
selected, weakly pulls the input to GND.
