R5109G SERIES Microprocessor Supervisory Circuit with 2 Clock Input Pin NO.EA-172-151222 OUTLINE The R5109G is a microprocessor supervisory circuit and has 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%(1).
