FEATURES

APPLICATIONS

R3130N/R3131N Series are CMOS-based low voltage detector ICs with built-in delay circuit, high Detector

These ICs can be used as system reset generator, and each of these ICs consists of a voltage reference, a

Detector threshold is fixed internally with high accuracy and requires no adjustment. When Supply Voltage

R3130N Series output “L” at detection mode, while R3131N Series output “H”.

Further, each of R3130N/R3131N Series embeds an output delay generator, when Supply Voltage crosses a

Output Delay Time can be selected. (Typ. 240ms is standard.)

Two output types, Nch open drain type and CMOS type, are available.

Since the package for these ICs is SOT23-3 (Mini-mold) package, high density mounting of the ICs on board
