The R5115 is a power management IC including an LDO regulator, a reset IC and a watchdog timer in a single chip. Designed with our independent technology, the R5115 features low supply current: typically 8.5 μA at operating mode, and typically 0.2 μA at standby mode. The watchdog timer turns off when the monitored MCU is set to a sleep mode. The window-type watchdog timer makes it possible to design a safer system by detecting errors caused not only by the over-time but by the short time.
WDT State:  OW (Open Window), RST (Reset),
CW (Close Window), IGN (Ignore)
WDT is initialized at each transition of WDT states. If a timer clock is entered into WDT during tOW, WDT is initialized and goes into CW. If a timer clock is not entered into WDT during tOW, WDT goes into RST to output a reset signal. If a timer clock is entered into WDT during tCW, WDT goes into RST to outs a reset signal. If a timer clock is not entered into WDT during tCW, WDT goes into OW. After RST, WDT goes into IGN and a timer clock input during this time period would be ignored.
