R3152N001A-TR-KE Nisshinbo

R3152N Series AEC-Q100 Compliant 42 V Input Window Voltage Detector for Automotive Applications No. EC-405-210316 OVERVIEW The R3152N 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. KEY BENEFITS 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. KEY SPECIFICATIONS SELECTION GUIDE Operating Voltage Range (Max.
