Description
The R3115Z Series is a CMOS-based voltage detector IC with high detector threshold accuracy and ultra-low supply current. It can be operated at an extremely low voltage and is commonly used for system reset. The IC consists of a voltage reference unit, comparator, resistor net for detector threshold setting, output driver, hysteresis circuit, and output delay circuit. The detector threshold is fixed internally with high accuracy and does not require any adjustment. It is available in two output types, Nch open drain and CMOS. The package is WLCSP-4-P2, allowing for high-density mounting on boards.
