LTC1728 is a triple supply monitor intended for systems with multiple supply voltages. This 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. It may also be configured to monitor any one or two VCC inputs instead of three, depending on system requirements. Typical applications are desktop computers, notebook computers, intelligent instruments, portable battery-powered equipment and network servers.
• ±1.5% threshold accuracy over temperature
• Power supply glitch immunity
• Input voltage rating is 1.8V
• Very low supply current is 10µA typical
• Guaranteed active-low RESET for VCC3>= 1V or VCC5/VCC25/VCC18>= 1V
• Ideal for power conscious systems
• 8-lead plastic SOT-23 package
• Temperature range from -40°C to 85°C
