The IMP811/IMP812 are low-power supervisors designed to monitor
voltage levels of 3.0V, 3.3V and 5.0V power supplies in low-power
microprocessor (μP), microcontroller (μC) and digital systems. Each fea-
tures a debounced manual reset input. The IMP811/812 are improved
drop-in replacements for the Maxim MAX811/812 with extended
temperature specifications to 105°C.

RESET
Input
A reset signal is issued if the power supply voltage drops below a preset
threshold and is asserted for at least 140ms after the supply has risen
above the reset threshold. The IMP811 has an active-low output RESET
that is guaranteed to be in the correct state for V
CC
down to 1.1V. The
IMP812 has an active-high output RESET. The reset comparator is
designed to ignore fast transients on V
CC
.
Low power consumption makes the IMP811/IMP812 ideal for use in
portable and battery-operated equipment. Available in a compact 4-pin
SOT143 package, the devices use minimal board space.
Six voltage thresholds are available to support 3V to 5V systems:
