R3152 Series

42V Input Window Voltage Detector

  • Consumer
  • Industrial
  • Automotive
  • PLP
  • AEC-Q100
  • RoHS

The R3152 is a window voltage detector suited for achieving the functional safety.

This device monitors over- and under- voltage of the output voltage from the power supply IC for a microprocessor and a sensor, and can prevent malfunction of system caused by abnormal voltage.

This product for industrial applications are characterized to -50°C, and operates in a wide temperature range from low temperature to high temperature.

  • A stable voltage with supplying the battery voltage can provide the power supply and the voltage supervising separately.
  • High-accuracy detection enables with Overvoltage/Undervoltage Detection Accuracy of -1.25%to 0.75% and Hysteresis of 1.5%.
  • Small package of SOT-23-6 is adopted, and a safe and secure pin assignment with considering a short among adjacent pins.
