R3118Q212C-TR-FE

R3118x SERIES LOW VOLTAGE DETECTOR with individual SENSE pin and delay function NO.EA-242-160229 OUTLINE The R3118x series are CMOS-based voltage detector ICs with individual sense pin, high detector threshold accuracy and delay time, 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 hysteresis comparator, resistors net for detector threshold setting, an output driver transistor, and a delay circuit. VDD supply pin for the IC and voltage supervisory sense pin are individual, therefore the output pin can keep "L" level even if the sense pin voltage is going down to 0V, or there is no indefinite range for the sense pin. Since a delay circuit is built-in, by connecting an external capacitor, any output delay time can be set. In the R3118x series, detector released delay time can be set, and detector delay time is not influenced by the external capacitor for the delay time. The detector threshold is fixed with high accuracy internally and does not require any adjustment. The tolerance of the detector threshold is ±22.5mV (−VDET_S
