Product Summary
The LTC1726ES8-5#TR is a triple supply monitor and microprocessor supervisory circuit with adjustable reset and watchdog functions intended for systems with multiple supply voltages. The LTC1726ES8-5#TR has a common open-drain reset output with an adjustable delay. The reset and watchdog time-out periods are both adjustable using external capacitors. Tight 1.5% accuracy specifications and glitch immunity ensure reliable reset operation without false triggering. The RST output is guaranteed to be in the correct state for VCC5/VCC25 or VCC3 down to 1V. The LTC1726ES8-5#TR may also be configured to monitor any one or two VCC inputs instead of three, depending on system requirements. Applications are desktop computers, notebook computers, intelligent instruments, portable battery-powered equipment, network servers.
