Power Supply Supervisor
The IMP809/IMP810 are 3.0V, 3.3V and 5.0V power supply supervisor cir-
cuits optimized for low-power microprocessor (µP), microcontroller (µC)
and digital systems. The IMP809/810 are improved drop-in replacements
for the Maxim MAX809/810 and feature 60% lower supply current.
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 V
CC
down to 1.1V.
The IMP810 has an active-high RESET output. The reset comparator is
designed to ignore fast transients on V
CC
.
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:
