Description
The R3111H331C-T1 is a voltage detector IC from the R3111x series designed for system reset purposes. These CMOS-based ICs have high detector threshold accuracy with ultra-low supply current and can be operated at very low voltage. Each IC in the R3111x series consists of 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 does not require any adjustment. The R3111x series offers three output types, including Nch open drain “L” type, Nch open drain “H” type, and CMOS type.
