ILC811/ILC812
Microprocessor Reset Circuits
General Description
The ILC811/ILC812 is a low cost microprocessor supervisory
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
accommodate systems operating at 3 V, 3.3 V or 5 V.
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 140 ms
after V
CC
has risen above the designated reset threshold. The
ILC811/ILC812 is available in a 4-pin SOT-143 package.
