R5115x Series 42 V System Power Supply with Ultra-low Power Window-type Watchdog Timer for Automotive Application

PublishTime：2021-04-25

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.
●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.
■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.
