APX811

APX811/812 4-Pin Microprocessor Supervisor With Manual Reset Features General Description Precision Monitor of(2.5V/3.0V/3.3V/5.0V) power supply voltage Full specified over temperature Manual reset input Available in four output configuration Push-pull RESET Active low(APX811) Push-pull RESET Active high(APX812) Power-on reset generator with fixed delay time 200ms SOT143: Available in “Green” Molding Compound (No Br, Sb) Lead Free Finish/RoHS Compliant (Note 1) The APX811/812 are used for microprocessor supervisory circuit to monitor the power supplies in These circuit 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 APX811/812 have push-pull outputs. The APX811 has an active low RESET output, while the APX812 has an active high RESET output. The APX811/812 devices incorporate a manual reset input, MR . A low level at MR causes RESET to become active. The APX811/2 are targeted at 2.5V, 3V, 3.3V and 5V powered systems and are available with different threshold voltages to meet the exact needs of the system. They are available in the space saving SOT143 package and operate over the whole industrial temperature range, -40 to 85°C. Applications Computers Controllers Intelligent Instruments Critical uP a...
