Description
The R3111x series is a CMOS-based voltage detector IC that features high detector threshold accuracy and ultra-low supply current. It is designed for system reset applications and can operate at an extremely low voltage. This IC includes a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, and a hysteresis circuit. The detector threshold is fixed internally with high accuracy and does not require any adjustment. Three output types are available: Nch open drain "L" type, Nch open drain "H" type, and CMOS type. The R3111x Series operates at a lower voltage than the Rx5VL series and can be driven by a single battery. This component is available in six different packages: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
