Description
The R3117K181C-TR is an IC chip that belongs to the R3115Z Series. The R3115Z Series is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current. It is designed for system reset and is particularly useful when operating at extremely low voltages. The ICs in this series include a voltage reference unit, a comparator, resistor net for detector threshold setting, an output driver, a hysteresis circuit, and an output delay circuit. The R3117K181C-TR has two output types available, including Nch open drain type and CMOS type. Furthermore, the high-density package (WLCSP-4-P2) makes it suitable for high-density mounting on boards.
