Description

General part information

LTC2909 Series

The LTC2909 is a dual input monitor intended for a variety of system monitoring applications. Polarity selection and a buffered reference output allow the LTC2909 to monitor positive and negative supplies for undervoltage (UV) and overvoltage (OV) conditions.The two inputs have a nominal 0.5V threshold, featuring tight 1.5% threshold accuracy over the entire operating temperature range. Glitch filtering ensures reliable reset operation without false triggering. A third fixed-threshold UVLO monitor on the part’s VCC(also 1.5% accuracy) is available for standard logic supplies.The common reset output has a timeout that may use a preset 200ms, be set by an external capacitor or be disabled. A three-state input pin sets the input polarity of each adjustable input without requiring any external components.The LTC2909 provides a highly versatile, precise, space-conscious, micropower solution for supply monitoring.ApplicationsDesktop and Notebook ComputersHandheld DevicesNetwork ServersCore, I/O MonitorAutomotive
