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 R5107G Series is a CMOS-based microprocessor supervisory circuit with high accuracy and ultra low supply current voltage detector, built-in delay circuit, and watchdog timer. It generates a reset output when the supply voltage drops below the threshold or the watchdog timer fails to detect the system clock from the microprocessor.

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.

The R3118x series are CMOS-based voltage detector ICs with individual sense pin, high detector threshold accuracy and delay time, and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example.

The R3116x series is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current. It can operate at an extremely low voltage and is used for system reset. Each IC in the series consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The detector threshold is internally fixed with high accuracy and does not require any adjustment. Two output types, Nch open drain type and CMOS type, are available. The R3116x series can be operated at a lower voltage than the R3112x series and can be driven by a single battery. Three types of packages, SOT-23-5, SC-82AB, and DFN(PLP)1010-4, are available.
