XC6138

Low Power, Voltage Detector with separated 76V VSEN pin for direct Voltage monitoring, ideal for Industrial Applications

 

XC6138 includes Delay Function, Manual Reset and Topr=125oC

The XC6138 has been designed to monitor 12 V and 24 V power rails, common in Industrial equipment. It can also be used to monitor the Voltage in Battery packs containing multiple cells in series.  Able to operate up to 125oC, the XC6138 has a separated VSEN pin rated to 76 V that can withstand Surge Voltages to 90.0 V for ≤400ms.

The Detect and Release voltage thresholds are optimised for each power source with users able to select from seven preset release/delay time ratios and the release and delay timing can be adjusted externally. Hysteresis width is also selectable between 5% and 50% of the detect voltage, with several options offered as standard.

The XC6138 is readily available in the industry standard SOT25 package or an ultra-small, leadless DFN1515-6A package, which measures only 1.5 x 1.5 x 0.38mm.

KEY FEATURES:

  • Monitor Voltage rails directly without needing dividing resistors
    • VSEN pin 76 V max.
    • Withstands surge voltages to 90 V for ≤ 400 ms
       
  • Specify Detect & Release voltages separately
    • Select optimum Voltage combination to match power supply fluctuations
       
  • Detect / Release delay with Manual RESET
    • Adjustable with an external capacitor
    • Selectable delay time ratio
  • Low Current Consumption
    • IDD 0.5 μA @ VDD=2.2 V
    • ISEN 0.15 μA @ VSEN=12 V
       
  • Small DFN1515-6A Package
    • Only 1.5 x 1.5 x 0.38mm
