The R5109G Series is a CMOS-based microprocessor supervisory circuit with high accuracy and ultra low supply current voltage detector. It has a built-in delay circuit and watchdog timer. The reset output is generated when the supply voltage is below the threshold or the watchdog timer does not detect the system clock from the microprocessor.
The Ricoh R5109G Series is a CMOS-based microprocessor supervisory circuit designed as a high-accuracy, ultra-low supply current voltage detector with a built-in delay circuit and watchdog timer. It generates a reset output when the supply voltage drops below a threshold or when the watchdog timer fails to detect the system clock from the microprocessor. The circuit includes a voltage detector for system reset and a watchdog timer with configurable timeout periods.
