Description
The ILC803, ILC809 and ILC810 are low cost
microprocessor supervisory circuits that assert a reset if the
power supply 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 designated reset threshold. The
ILC803, ILC809 and ILC810 are available in either a 3-Pin
SOT-23 package or a 3-Pin SC70 packages.
