R5107G SERIES

AEC-Q100 Grade 2 Compliant

Microprocessor Supervisory Circuit with Manual Reset for Automotive Applications

NO.EC-170-130723

OUTLINE

The R5107G Series are CMOS-based microprocessor supervisory circuit and have 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 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%^.

The function to stop supervising clock by the watchdog timer (INH function) and manual reset function are built

in this IC.

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

timer. The package of R5107G is SSOP-8G.
