General Description
The ILC803, ILC809 and ILC810 are low cost microproces-
sor supervisory circuits that assert a reset if the power sup-
ply drops below a designated threshold. Several different
reset thresholds are available to accommodate systems
operating at 3V, 3.3V or 5V.
The ILC803 has an open drain output stage with active
low RESET output
The ILC809 has an active low RESET output, while
the ILC810 offers an active high RESET output. The
reset output is guaranteed to remain asserted for a
minimum of 140ms after V
CC
has risen above the des-
ignated reset threshold. The ILC803, ILC809 and
ILC810 are available in either a 3-Pin SOT-23 pack-
age or a 3-Pin SC-70 packages.
