3-PIN MICROPROCESSOR RESET CIRCUITS
General Description
The APX809/810 are used for microprocessor (µP) supervisory
circuits to monitor the power supplies in µP and digital systems.
They provide excellent circuit reliability and low cost by
eliminating external components and adjustments when used
with +5V, +3.3V, +3.0V powered circuits.
These circuits perform a single function: they assert a reset
signal whenever the V
threshold, keeping it asserted for at least 240ms after V
risen above the reset threshold. Reset thresholds suitable for
operation with a variety of supply voltages are available. The
APX809/810 have push pull outputs. The APX809 have an active
low
RESET output. The reset comparator is designed to ignore fast
transients on V
correct logic state for V
the APX809/810 ideal for use in portable equipment. The
APX809/810 is available in a 3-pin SOT23 and SOT23R
packages.
