AP1722A-18PC - Brand New Central Semiconductor IC Chips
-
General Description
The AP1701/2/3/4 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 VCCsupply voltage declines below a preset threshold, keeping it asserted for at least 240ms after VCChas
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 VCCdown 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 SC59 package.Features
