General Description
The AP1701/2/3/4 are used for microprocessor (P)
supervisory circuits to monitor the power supplies in
P 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 VCC supply voltage
declines below a preset threshold, keeping it
asserted for at least 240ms after VCC has risen
above the reset threshold. Reset thresholds
suitable for operation with a variety of supply
voltages are available. The AP1701/2/3/4 have
push pull outputs. The AP1701/3 have an active low
RESET output, while the AP1702/4 has an active
high RESET output. The reset comparator is
designed to ignore fast transients on VCC, and the
outputs are guaranteed to be in the correct logic
state for VCC down to 1V. Low supply current
makes the AP1701/2/3/4 ideal for use in portable
equipment. The AP1701/2/3/4 is available in a 3-pin
SOT23,TSOT23 package.
