Microprocessor Supervisory Circuit

The R5109G Series are CMOS-based con Supervisory Circuit or high accuracy and ultra low supply current voltage detector with built-in delay and watchdog Timer When the VDD voltage is down across the threshold, or the watchdog Timer does not detect the system Clock from the con, the reset output is generated. The voltage detector circuit is used for the system reset, etc. The detector threshold is fixed internally, and the tolerance 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. When the VDD supply voltage becomes higher than the released voltage, the reset state will be maintained during the delay time. The time out period of the watchdog Timer CAN be also set with an external capacitor. The output type of the reset is selectable, Nch open-drain, or CMOS. The function to stop supervising Clock by the watchdog Timer (INH function) and the function to supervise two different Clocks are built in this IC. The package is small SSOP-8G.
