Introduction
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. The RST output is guaranteed to be in the correct state for VCC18 or VCC3 down to 1V. The LTC1985 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 LTC1985 ideal for power conscious systems. The LTC1985 is available in a 5 - lead SOT - 23 package.
Features
- Monitors Three Inputs Simultaneously: 3V, 1.8V and Adjustable
- ±1.5% Threshold Accuracy Over Temperature
- Very Low Supply Current: 10μA Typ
- 200ms Reset Time Delay
- Power Supply Glitch Immunity
- Guaranteed RESET for VCC3 ≥ 1V or VCC18 ≥ 1V
- 3V Active - Low Push - Pull Reset Output
- 5 - Lead SOT - 23 Package
Applications
- Desktop Computers
- Notebook Computers
- Intelligent Instruments
- Portable Battery - Powered Equipment
- Network Servers
