Description
LTC1985-1.8 Micropower Precision Triple Supply Monitor with Push-Pull Reset Output in a 5-Lead SOT-23 Package U U .
Features
* s Monitors Three Inputs Simultaneously: 3V, 1.8V and Adjustable s ±1.5% Threshold Accuracy Over Temperature s Very Low Supply Current: 10µA Typ s 200ms Reset Time Delay s Power Supply Glitch Immunity s Guaranteed RESET for VCC3 ≥ 1V or VCC18 ≥ 1V s 3V Active-Low Push-Pull Reset Output s 5-Lead SOT-2Applications
* this is not a problem since most microprocessors and other circuits do not operate with the supply voltage less than 1V. In applications where the RST output must be valid down to 0V the addition of a pulldown resistor from RST to ground will ensure RST is held low.
