R5106N SERIES

Microprocessor Supervisory Circuit

NO.EA-169-080707

OUTLINE

The R5106N Series are CMOS-based microprocessor supervisory circuit, or 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%*. When the supply voltage becomes higher

than the released voltage, the reset state will be maintained during the delay time. The output type of the reset

is selectable, Nch open-drain, or CMOS.

The time out period of the watchdog timer can be also set with an external capacitor, and the accuracy is

±33%*.

There is a function to stop supervising clock by the watchdog timer (INH function).

There are another 4 products by the difference of packages and the function of voltage detector and

watchdog timer. The package of R5106N is SOT-23-6.
