AP1701/2/3/4
3-PIN MICROPROCESSOR RESET CIRCUITS
• Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages
• Fully Specified Over Temperature
• Available in three Output Configurations
• Push-Pull RESET Low Output AP1701/3
• Push-Pull RESET High Output AP1702/4
• 200ms Min. Power-On Reset Pulse Width
• 20µA Supply Current Typ.

• Green Packages SC59-3L and SOT23
• Lead Free Finish / RoHS Compliant Note 1

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 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 SC59 package.
