The R5108G series are CMOS-based microprocessor supervisory circuits, or high accuracy and ultra low supply current voltage detectors with built-in delay circuit and watchdog timer. When the SENSE voltage is down across the threshold, or the watchdog timer does not detect the system clock from the microprocessor, the reset output is generated. The voltage detector circuit is used for the system reset, etc. The detector threshold is fixed internally, and the accuracy is ±1.0%. The released delay time (Power-on Reset Delay) circuit is built-in, and output delay time is adjustable with an external capacitor, and the accuracy is ±16%∗. When the SENSE voltage becomes the released voltage, the reset state will be maintained during the delay time. The output type of the reset is selectable, Nch open-drain, or CMOS. The time out period of the watchdog timer can be also set with an external capacitor, and the accuracy is ±33%∗. There is a function to stop supervising clock by the watchdog timer (INH function). A necessary voltage source can be supervised with SENSE pin. There are another 4 products by the difference of packages and the function of voltage detector and watchdog timer. The package of R5108G is SSOP-8G.

The R5106N series is a CMOS-based microprocessor supervisory circuit, or high accuracy and ultra low supply current voltage detector with built-in delay circuit and watchdog timer. When the supply voltage is down across the threshold, or the watchdog timer does not detect the system clock from the microprocessor, the reset output is generated. The voltage detector circuit is used for the system reset, etc. The detector threshold is fixed internally, and the accuracy is ±1.0%. The released delay time (Power-on Reset Delay) circuit is built-in, and output delay time is adjustable with an external capacitor, and the accuracy is ±16%*. When the supply voltage becomes higher than the released voltage, the reset state will be maintained during the delay time. The output type of the reset is selectable, Nch open-drain, or CMOS. The time out period of the watchdog timer can be also set with an external capacitor, and the accuracy is ±33%*. There is a function to stop supervising clock by the watchdog timer (INH function). There are another 4 products by the difference of packages and the function of voltage detector and watchdog timer. The package of R5106N is SOT-23-6.
