Description
The Q53121-3S2 is a voltage detector IC in the R3111 Series. It is designed with high detector threshold accuracy and ultra-low supply current. This IC can be operated at an extremely low voltage and is commonly used for system reset purposes. It 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. Two output types, Nch open drain type, and CMOS type are available.
