R3152 Series
42V Input Window Voltage Detector

Product Specifications

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.

  • 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.

R3152 Series for Industrial

This product is a high-reliability semiconductor device for industrial application that has passed both the screening at high temperature and the reliability test with extended hours. Ricoh accommodates requests including the long-time operation and high temperature environment use.


APPLICATIONS

  • Industrial equipments such as FAs and smart meters
  • Equipments used under high-temperature conditions such as surveillance camera and vending machine
  • Equipments accompanied by self-heating such as motor and lighting

Operating Temperature Range : -50°C to 125°C


Tjmax 150°C

Unlike the rating of the products for consumer applications at Tjmax = 125°C, the products for automotive applications are rated at high temperature of Tjmax = 150°C. The power dissipation is also rated at high temperature.
