1 / 9 page  APX809/810 3-PIN MICROPROCESSOR RESET CIRCUITS APX809/810 Rev. 3 1 of 9 MARCH 2008 www.diodes.com © Diodes Incorporated Features General Description The APX809/810 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. • 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 Active Low (APX809) • Push-Pull RESET Active High (APX810) 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 APX809/810 have push pull outputs. The APX809 have an active low RESET output, while the APX810 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 APX809/810 ideal for use in portable equipment. The APX809/810 is available in a 3-pin SOT23 and SOT23R package. • 200ms Typ Power-On Reset Pulse Width • 30µA Supply Current (Typ.) • Guaranteed Reset Valid to VCC = +1V • No External Components • SOT23 and SOT23R: Available in “Green” Molding Compound (No Br, Sb) • Lead Free Finish/RoHS Compliant (Note 1) Applications • Computers • Controllers • Intelligent Instruments • Critical µP and µC Power Monitoring • Portable/Battery Powered Equipment • Automotive Ordering Information APX 8XX XX XX X X Voltage Package Packing 46 : 4.63 44 : 4.38 40 : 4.00 31 : 3.08 29 : 2.93 26 : 2.63 23 : 2.25 SA : SOT23 -7 : Taping Enable 09 : Active-Low 10 : Active-High Lead Free G : Green SR : SOT23R - 7” Tape and Reel Device Package Code Packaging (Note 2) Quantity Part Number Suffix APX809-XXSA SA SOT23 3000/Tape & Reel -7 APX810-XXSA SA SOT23 3000/Tape & Reel -7 APX809-XXSR SR SOT23R 3000/Tape & Reel -7 APX810-XXSR SR SOT23R 3000/Tape & Reel -7 Notes: 1.
