R3160 Series
Low Supply Current 60 V Input Voltage Detector

Product Specifications

The R3160 is a 60 V-input voltage detector provided with high detector threshold accuracy and low supply current. This device offers a direct-monitoring of 24-/48-V battery and a detection of low-voltage battery state.

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

  • Enables a direct-monitoring of battery voltage and can be used for an early warning of low-voltage battery state.
  • Provides a wide-range detector threshold of 10 V to 48 V and a high-accuracy of ±1.5% to ±1.75%.
  • Available in a small SOT-23-6 package.
