Description
The R3111x series is a CMOS-based voltage detector IC that offers high detector threshold accuracy and ultra-low supply current. It is designed for system reset applications and operates at an extremely low voltage. The IC consists of 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. The R3111x series is available in three output types: Nch open drain "L" type, Nch open drain "H" type, and CMOS type. Compared to the Rx5VL series, the R3111x series can be operated at a lower voltage and can be driven by a single battery. It comes in six different package options: TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.Specifications and Features
