R5107G SERIES

AEC-Q100 Compliant

Microprocessor Supervisory Circuit with Manual Reset for Automotive Applications

NO.EC-170-180222

OUTLINE

The R5107G 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% (R5107Gxx1x-TR-JE: −40°C ≤ Ta ≤ 105°C) ⁽.

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.
