Description
The R3111Q521C-TR is a voltage detector IC that belongs to the R3111x series. This is a CMOS-based IC that delivers high detector threshold accuracy and ultra-low supply current, which can operate at an extremely low voltage. The IC is utilized mainly for system reset. Each of these ICs comprises a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver, and a hysteresis circuit. The detector threshold is internally fixed with high accuracy and doesn't require any adjustment. It is available in three output types, Nch open drain “L” type, Nch open drain “H” type, and CMOS type. There are six packages available, TO-92, SOT-89, SOT-23-3, SOT-23-5, SC-82AB, and SON1612-6.
