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.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte tin
plate plus anneal (e3 termination finish, which is 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.

FUNCTION DESCRIPTION
Bias IC from nominal 2.7V to 4V
PGOOD is the boolean AND function of all the UV inputs being satisfied. This is an open drain output and
can be pulled high to the appropriate level with an external resistor. Additionally a 20kpull up to VDD is
provided internally.
Enabling input for supervisory function. Has a 10µA pull-up to VDD
IC ground
These inputs provide for a programmable monitored voltage threshold referenced to an internal 0.63V
reference. These inputs have a 30µs glitch filter to prevent transient upsets from being recognized by
PGOOD.
