The IMP809/ IMP810 are 3.0V, 3.3V and 5.0V power supply supervisor
circuits optimized for low-power microprocessor (μP), microcontroller
(μC) and digital systems. The IMP809/ 810 are improved drop-in replace-
ments for the Maxim MAX809/ 810 and feature 60% lower power con-
sumption.
A reset signal is issued if the power supply voltage drops below a preset
reset threshold and is asserted for at least 140ms after the supply has
risen above the reset threshold. The IMP809 has an active-low RESET
output that is guaranteed to be in the correct state for VCCdown to 1.1V.
The IMP810 has an active-high RESET output. The reset comparator is
designed to ignore fast transients on VCC.
Low supply current makes the IMP809/ IMP810 ideal for use in portable
and battery operated equipment. The IMP809/ IMP810 are available in a
compact 3-pin SOT23 package.
Six voltage thresholds are available to support 3V to 5V systems:
