OUTLINE
R3132x/R3133x Series are CMOS-based low voltage detector ICs with built-in delay circuit, high detector
threshold accuracy, and ultra low supply current, which can operate at low voltage.
These ICs can be used as system reset generators, and each of these ICs consists of a voltage reference, a
comparator, resistors for setting voltage detector threshold, an output driver transistor, manual reset circuit, and
an output delay generator.
Detector threshold is fixed internally with high accuracy and requires no adjustment. When a supply voltage
crosses a setting detector threshold voltage from a high value to a lower value, this IC generates reset signal.
R3132x Series output “L” at its detect, while R3133x Series output “H”.
Since each of R3132x/R3133x Series embeds an output delay generator, during a setting 240ms delay time,
which is fixed in the IC, this IC keeps the reset condition after they are released. Released conditions are the
case when a supply voltage crosses a setting detector threshold voltage from a low value to a higher value, or
when this IC is released from manual reset.
Two output types, Nch open drain type and CMOS type, are available.
Since the package for these ICs are ultra small SC-82AB package and SON1612-6, high density mounting of
the ICs on board is possible.
