The APX803/D 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
declines below a preset threshold, keeping it asserted for a
fixed period of time after V
threshold. For the APX803D this period is a minimum of 1ms
while for other APX803 variants it is at least 140ms. The reset
comparator is designed to ignore fast transients on V
the outputs are guaranteed to be in the correct logic state for
V
The APX803 is available with different reset thresholds
suitable for operation with a variety of supply voltages,
however the APX803D is available with a 2.93V threshold
voltage.
The APX803/D have an open collector active low
output and compliment Diodes APX809/10 which have push-
pull output stages.. Low supply current makes the APX803/D
ideal for use in portable equipment. The APX803/D are
available in two pin out variants of the 3-pin SOT23 package.
