1 / 10 page  APX803 3-PIN MICROPROCESSOR RESET CIRCUIT APX803 1 of 10 MARCH 2010 Document number: DS32132 Rev. 1 – 2 www.diodes.com © Diodes Incorporated • Precision Monitoring of +2.5V, +3V, +3.3V, and +5V Power-Supply Voltages • Fully Specified Over Temperature • Available in three Output Configurations • Open-drain RESET Active Low • 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) The APX803 is 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 on power up and whenever the VCC supply voltage declines below a preset threshold, keeping it asserted for at least 140ms after VCC has risen above the reset threshold. Reset thresholds suitable for operation with a variety of supply voltages are available. The APX803 have an open collector active low 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 APX803 ideal for use in portable equipment. The APX803 is available in two pin out variants of the 3-pin SOT23 and SOT23R packages. • Computers • Controllers • Intelligent Instruments • Critical µP and µC Power Monitoring • Portable/Battery Powered Equipment APX803 GND RESET Vcc Microprocessor Vcc GND RESET INPUT Vcc CIN 100nF Features General Description Applications Typical Application Circuit |
