Data Sheet / Flyer
Data Sheet * Flyer

The R3150N is a CMOS-based voltage detector IC that provides high-voltage resistance, high voltage accuracy and low supply current. This device is suitable for battery voltage supervisor. The R3150NxxxA/ B provide VDD pin detection and the R3150NxxxE/ F provide SENSE pin detection. Detector threshold and Release voltage can be specified separately. Both the detector threshold accuracy and the release voltage accuracy are ±1.5% (25ºC) (Detector Threshold Hysteresis is 5% to 20%).

The detect output delay time and the release output delay time (Power-on Reset Time) are adjustable by using external capacitors. The output types are Nch open drain “L” output and Nch open drain “H” output.

The R3150N is available in SOT-23-6 package that is possible to achieve high-density mounting on boards.

Operating Voltage Range (Maximum Rating) R3150NxxxA/ B: 1.4V to 36.0V (50.0V)
