 R3130NxxB/D/H (SOT23-3) are the limited products and R3131N (SOT-23-3) is the discontinued product as of March, 2016.
R3130N/R3131N SERIES Low Voltage Detector with Built-in Delay Circuit NO.
EA-073-160315 OUTLINE R3130N/R3131N Series are CMOS-based low voltage detector ICs with built-in delay circuit, high Detector Threshold accuracy and ultra low supply current which can be operated at low voltage.
These ICs can be used as system reset generator, and each of these ICs consists of a voltage reference, a comparator, resistors for setting voltage detector threshold, an output driver transistor, and an output delay generator.
Detector threshold is fixed internally with high accuracy and requires no adjustment.
When Supply Voltage crosses a setting detector threshold voltage from a high value to a lower value, this IC generates reset signal.
R3130N Series output “L” at detection mode, while R3131N Series output “H”.
Further, each of R3130N/R3131N Series embeds an output dela...
