Quad Voltage Monitor
The ISL88041 is a quad voltage-monitoring supervisor
designed to monitor voltages ≥0.7V. Low voltage detection
circuitry protects the user 's system from low voltage
conditions, resetting the system when any of the monitored
power supply voltages V1MON-V4MON fall below their
respective minimum voltage thresholds. The reset signal
remains asserted until all of these voltages return to proper
operating levels and stabilize.
Each rail’s VMON point is independently adjustable by using
an external resistor divider. The VMON inputs will ignore
transients of less than 30µs on the monitored supplies, and
the RST output is guaranteed to be valid down to VDD = 1V.
The RST output is open-drain to allow ORing of multiple
signals and interfacing to a wide range of logic levels. Also,
the MR input allows the user to assert reset when this input
is pulled low.

NOTE: Intersil Pb-free plus anneal 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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
