DESCRIPTION
The APE6809_6812 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, +2.5V
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 200ms after
VCC has risen above the reset threshold. Reset thresholds
suitable for operation with a variety of supply voltages are
available. The APE6809_6812 have push pull outputs. The
APE6809/APE6811 have an active low RESET output, while
the APE6810_6812 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 1.0V. Low supply current makes
the APE6809_6812 ideal for use in portable equipment. The
APE6809_6812 is available in a 3-pin SOT-23 and SC-70
package.
