The ISL6536 is a four channel supervisory IC designed to monitor voltages >, = 0. 7V. This IC bias range is from 2. 7V to 4V but can supervise any positive voltage using an external resistor divider to translate to a lower voltage for comparison to the internal 0. 63V reference. Once properly biased and enabled when all four voltage monitor (VMON) inputs are satisfied the PGOOD output will be immediately released to go high to signal that voltage is valid on all four rails. Subsequently when the monitored voltage on any rail drops below its user defined threshold point, the PGOOD output is pulled low. Each rail's VMON point is independently adjustable with a resistor divider. The PGOOD output is guaranteed to be valid with IC bias lower than 1V. The VMON inputs will ignore 30µs transients on the monitored supplies. The PGOOD output is an open-drain to allow ORing of multiple signals and interfacing to a range of logic levels. The ENABLE input provides for a reset of the PGOOD output when it is pulled down below 0. 5V. With an internal 10µA pull-up to VDD it can be signalled with common logic or pulled to ground with a push button switch.

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
