LTC2919HMS-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. 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. A three-state input pin sets the input polarity of each adjustable input without requiring any external components. It provides a highly versatile, precise, space conscious, micropower solution for supply monitoring. It is widely used in application such as desktop and notebook computers, network servers, core, I/O monitor, automotive etc.
