Datasheet
1 General Description
The AS1916 - AS1918 mcroprocessor supervisory circuits were
designed to generate a reset when the monitored supply voltage falls
below a factory-trimmed threshold. The reset remains asserted for a
mnimumtimeout period after the supply voltage stabilizes.
Guaranteed to be in the correct state for V
CC
higher than +1.0V,
these devices are ideal for portable and battery-powered systems
with strict monitoring requirements.
The devices feature factory-trimmed thresholds to monitor a supply
voltage between 1.8 and 3.6V.
The devices are available with the reset output types listed in
Table
1
.
The AS1916 - AS1918 include a manual-reset input for systems that
never fully power down the mcroprocessor.
Additionally, these devices feature a watchdog timer to help ensure
that the processor is operating within proper code boundaries.
The AS1916 - AS1918 are available in a 5-pin SOT23 package.
