ISL6536
Four Channel Supervisory IC
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 10uA pull-up to VDD it can be signalled with
common logic or pulled to ground with a push button switch.

NOTE: Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
