R3111E (TO-92) is the discontinued product as of April, 2017.
R3111x SERIES
LOW VOLTAGE DETECTOR
NO.EA-056-170428
OUTLINE
The R3111x series are CMOS-based voltage detector ICs with high detector threshold accuracy and ultra-low supply current, which can be operated at an extremely low voltage and is used for system reset as an example.
Each of these ICs 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 with high accuracy internally and does not require any adjustment.
Three output types, Nch open drain “L” type, Nch open drain “H” type and CMOS type are available.
