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...
