Microprocessor Supervisory Circuit

R5107G SERIES

OUTLINE

The R5107G Series are CMOS-based µ 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 µ 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 manual reset function are built in this IC. The

package is small SSOP-8G.
