| R3119N Series |
LOW VOLTAGE DETECTOR |
|
| R3119N series are wide input voltage range (50V) voltage detector with high detector threshold accuracy and ultra-low supply current. Each of these ICs consists of a voltage reference unit, a comparator, resistors for detector threshold setting, an output driver and a hysteresis circuit. R3119NxxxA (CD pin type) has the CD pin, which is for setting delay time and R3119NxxxE has the SENSE pin. The detector threshold is internally fixed with high accuracy (±1.5% at Ta=25°C). The output type is Nch open drain type. |
