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 Ricoh R5107G Series is a CMOS-based microprocessor supervisory circuit designed as a high-accuracy, ultra-low supply current voltage detector. It features a built-in delay circuit for power-on reset and an integrated watchdog timer to monitor system clocks. When the supply voltage drops below a threshold or the watchdog timer fails to detect the clock signal, the device generates a reset output.
| Operating Voltage Range | 0.9V to 6.0V |
|---|---|
