Description
General part information
LTC1985-1.8 Series
The LTC1985-1.8 is a triple supply monitor intended for systems with multiple supply voltages. The 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.TheRSToutput is guaranteed to be in the correct state for VCC18or VCC3down to 1V. The LTC1985 may also be configured to monitor any one or two VCCinputs instead of three, depending on system requirements.Very low (10µA typical) supply current makes the LTC1985 ideal for power conscious systems.The LTC1985 is available in a 5-lead SOT-23 package.ApplicationsDesktop ComputersNotebook ComputersIntelligent InstrumentsPortable Battery-Powered EquipmentNetwork Servers
