The LTC2919CMS-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.
