MAX709L

电源监测器，带有复位; \n• +5V, +3.3V, and +3V Versions \n• No External Components \n• Low Cost \n• Precise Power-Down Reset Threshold \n• 140ms Min Power-On Reset Delay \n• Immune to Short Negative VCC Transients \n• 8-Pin DIP, µMAX, and SO Packages \n• Low Supply Current:\n• 35µA - MAX709R/S/T \n• 65µA - MAX709L/M;

The MAX709 provides a system reset during power-up, power-down, and brownout conditions. When VCC falls below the reset threshold, RESET goes low and holds the µP in reset for 140ms min after VCC rises above the threshold.\n The RESET output is guaranteed to be in the correct state with VCC down to 1V. The MAX709 provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3V powered systems. The MAX709 is available 8-pin DIP, µMAX®, and SO packages.
