LTC2919CMS-3.3#PBF

LTC2919 is a triple/dual input monitor intended for a variety of system monitoring applications. Polarity selection and a buffered reference output allow the device 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. 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. It provides a highly versatile, precise, space conscious, micropower solution for supply monitoring. It is used in application such as desktop and notebook computers, network servers, core, I/O monitor, automotive etc.
