LTC1727EMS8-5#PBF

LTC1727EMS8-5#PBF is a triple supply monitor intended for systems with multiple supply voltages. Each supply monitor has its own open-drain output for individual supply monitoring. A common open-drain reset output remains low until all three supplies have been in compliance for 200ms. Tight 1.5% accuracy specifications and glitch immunity ensure reliable reset operation without false triggering. The active-low RST output is guaranteed to be in the correct state for VCC5/VCC25/VCC18 or VCC3 down to 1V. The device may also be configured to monitor any one or two VCC inputs instead of three, depending on system requirements. Very low (10µA typical) supply current makes the device ideal for power-conscious systems. Typical applications are desktop computers, notebook computers, intelligent instruments, portable battery-powered equipment and network servers.
