R5106N SERIES AEC-Q100 Compliant Microprocessor Supervisory Circuit with Inhibit pin for Automotive Applications NO. EC-169-200602 OUTLINE The R5106N 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 (1) adjustable with an external capacitor, and the accuracy is 16% (R5106Nxx1x-TR-JE: 40C Ta 105C) . 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 (1) 33% . There is a function to stop supervising clock by the watchdog timer (INH function). The package of R5106N is SOT-23-6. FEATURES Supply Current (ISS) .......................................................
