18 / 71 page  ADM1260 Data Sheet Rev. 0 | Page 18 of 71 VXx PINS AS DIGITAL INPUTS As described in the Supply Supervision with the VXx Inputs section, the VXx input pins on the ADM1260 have dual functionality. The second function is as a digital logic input to the device. Therefore, the ADM1260 can be configured for up to five digital inputs. These inputs are TTL-/CMOS-compatible inputs. Standard logic signals can be applied to the pins: reset from reset generators, power-good (PWRGD) signals, fault flags, and manual resets. 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, a pulse of programmable width is output from the digital block once the logic transition is detected. 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 function 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 VXx pin has a weak (10 μA) pull-down current source available for placing the input into a known condition, even if left floating. The current source, if selected, weakly pulls the input to GND. DETECTOR VXx (DIGITAL INPUT) GLITCH FILTER VREF = 1.4V TO SEQUENCING ENGINE + – Figure 25. VXx Digital Input Function |
