The APX803 is 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 on power up and whenever the V CC supply voltage
declines below a preset threshold, keeping it asserted for at least
140ms after V CC has risen above the reset threshold. Reset
thresholds suitable for operation with a variety of supply voltages
are available. The APX803 have an open collector active low
RESET output. The reset comparator is designed to ignore
fast transients on V CC , and the outputs are guaranteed to be in
the correct logic state for V CC down to 1V. Low supply current
makes the APX803 ideal for use in portable equipment. The
APX803 is available in two pin out variants of the 3-pin SOT23
and SOT23R packages.
