Additional Details

The LTC2919 is a triple/dual input 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 undervoltage (UV) and overvoltage (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 V_CC pin provides a third input supply monitor for a 2.5V, 3.3V 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.

The LTC2919 provides a highly versatile, precise, space-conscious, micropower solution for supply monitoring.
