Low Voltage Detector with built-in Delay Circuit
R3132QxxA/C, R3133QxxA/C
Rev. 1.10 1

OUTLINE
R3132Q/R3133Q 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.
R3132Q Series output "L" at its detect, while R3133Q Series output "H".
Since each of R3132Q/R3133Q 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 SC82-AB package, high density mounting of the ICs on board is
possible.
