Product Overview

The LTC2919HMS-5#PBF is a triple input Voltage Monitor intended for a variety of system monitoring applications. Polarity selection and a buffered reference output allow the LTC2919 to monitor positive and negative supplies for under-voltage (UV) and over-voltage (OV) conditions. The two adjustable inputs have a nominal 0.5V threshold, featuring tight 1.5% threshold accuracy over the entire operating temperature range. Glitch filtering ensures outputs operate reliably without false triggering. An accurate threshold at the VCC pin provides a third input supply monitor for a 2.5, 3.3 or 5V supply. Two independent output pins indicate the status of each adjustable input. A third common output provides a configurable reset timeout that may be set by an accurate internal 200ms timer, programmed with an external capacitor or disabled for a fast response. A three-state input pin sets the input polarity of each adjustable input without requiring any external components.
  • Two low voltage adjustable inputs (0.5V)
  • Accurate UVLO provides a third monitor input
  • Open-drain RST\, OUT1 and OUT2 outputs
  • Pin selectable input polarity allows negative, UV and OV monitoring
  • Input glitch rejection
  • Adjustable reset timeout period
  • Selectable internal timeout saves components
  • Outputs guaranteed low with VCC = 0.5V
  • Buffered 1V reference for negative supply offset
  • ±1.5% Guaranteed threshold accuracy
  • 6.5V Shunt regulator for high voltage operation
  • 50µA Low quiescent current
