Product Overview

The LTC2909ITS8-5#PBF is a dual input Precision Voltage Monitor with open-drain RST\ output. It is 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 under-voltage (UV) and over-voltage (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.
  • Two low voltage adjustable inputs (0.5V)
  • Pin selectable input polarity allows negative and OV monitoring
  • Buffered 1V reference for negative supply offset
  • Input glitch rejection
  • Adjustable reset timeout period
  • Selectable internal timeout saves components
  • Accurate UVLO for 2.5, 3.3 and 5V systems
  • Ultra-low voltage reset of VCC=0.5V guaranteed
  • 6.5V Shunt regulator for high voltage operation
  • 50µA Low quiescent current
