The ILC811/ILC812 is a low cost microprocessor superviso-
ry circuit that asserts a reset if the power supply drops below
a designated threshold or the manual reset pin is forced low.
Several different reset thresholds are available to accom-
modate systems operating at 3V, 3.3V or 5V.
The ILC811 has an active low RESET output, while the
ILC812 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 ILC811/ILC812 is available in a 4-pin SOT-143
