Multiple Voltage Supervisory ICs
The ISL6131 and ISL6132 are a family of high accuracy
multi voltage supervisory ICs designed to monitor voltages
greater than 0.7V in applications ranging from
microprocessors to industrial power systems. The ISL6131
is an undervoltage four supply supervisor whereas the
ISL6132 is a two voltage supervisor monitoring both for
undervoltage (UV) and overvoltage (OV) conditions.
Both ICs feature four external resistor programmable voltage
monitoring (VMON) inputs each with a related STATUS
output that individually reports the related monitor input
condition. In addition there is a PGOOD (power good) signal
that asserts high when the STATUS outputs are in their
correct state. There is a stability delay of approximately
160ms to ensure that the monitored supply is stable before
STATUS and PGOOD are released to go high. The PGOOD
and STATUS outputs are open-drain to allow ORing of the
signals and interfacing to a wide range of logic levels.
STATUS and PGOOD outputs are guaranteed to be valid
with IC bias lower than 1V eliminating concern about
STATUS and PGOOD outputs during IC bias up and down.
VMON inputs are designed to ignore momentary transients
on the monitored supplies.

NOTE: 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.
