Product Overview

The LTC2911CTS8-5#TRMPBF is a triple-supply low-power high accuracy Precision Monitor with power-fail comparator. Reset timeout may be selected with an external capacitor or set to an internally generated 200ms. The V1 pin monitors a 3.3V supply. The V2 pin monitors a 5, 2.5, 1.8, 1.2V or adjustable supply. A third adjustable input has a nominal 0.5V threshold allowing a resistive divider to configure its threshold. All three comparators feature a tight 1.5% threshold accuracy over the entire operating temperature range while a glitch filter ensures reliable reset operation. A spare comparator can be configured to provide early warning of a low voltage condition. It causes the PFO output to pull low when the voltage of the PFI input falls below 0.5V, allowing the power-fail threshold to be configured with a resistive divider. A latch feature on the TMR pin allows the RST output to be latched to prevent system resets, simplifying margin testing.
  • RST\ state can be held for margining
  • Input glitch immunity
  • Adjustable reset timeout period
  • Monitors three inputs of 3.3, 1.2V, ADJ
  • Selectable internal timeout saves components
  • 30µA Typical low supply current
