R5115x-Y Series 42 V System Power Supply with Ultra-low Power Window-type Watchdog Timer for Industrial Application No. EY-409-200326 OVERVIEW The R5115x is a system power supply IC with an ultra-low power window-type watchdog timer (VR + VD + WDT) that has an input voltage range of 3.5 V to 42 V. This is a high-reliability semiconductor device for industrial application (-Y) that has passed both the screening at high temperature and the reliability test with extended hours. KEY BENEFITS Consists of a voltage regulator, a voltage detector and a watchdog timer that provides a system power supply, a power supply voltage monitoring and a system malfunction monitoring. (1) Equipped with an auto monitoring stop to cease the watchdog timer monitoring at light load. Outputs a reset signal from watchdog timer when a pulse signal period is too short or too long.
