R3119N Series is a 36V input (absolute maximum ratings: 50V) voltage detector with high detector threshold accuracy and ultra-low supply current.
The Ricoh R3119N Series consists of CMOS-based ICs designed as 36V input voltage detectors. These devices feature high detector threshold accuracy and an ultra-low supply current of approximately 3.3uA. The series is available in two types: the R3119NxxxA with a Co pin for setting output delay time, and the R3119NxxxE with a SENSE pin.
| Supply Current | Typ. 3.3uA |
|---|---|
| Detector Threshold Accuracy | 1.5% |
| Package Type | SOT-23-5 |
The series includes R3119NxxxA with a Co pin for setting delay time and R3119NxxxE with a SENSE pin.
The absolute maximum supply voltage rating is 50V for the Co pin type and 7.0V for the SENSE pin type.
It is used for CPU and logic circuit reset, battery checkers, battery back-up circuits, and power failure detectors.
