R3116x Series
0.8% Accuracy, 0.5V Operating Voltage Detector with Delay Function
The R3116x Series are CMOS-based voltage detector ICs with the built-in output delay circuit. The Series can operate at low voltage
from 0.5V and the detector threshold can be specified from 0.7V. The detector threshold accuracy as high as
±
0.8% helps to increase
stable operating area coupled with lower voltage. Additionally, the high accuracy output delay time at
±
15% allows easy control of
the start-up sequence. In addition to SOT-23-5 and SC-82AB packages, a 1mm square DFN(PLP)1010-4 package is also available.

HIGHER ACCURACY OUTPUT DELAY TIME
WHAT IS DFN(PLP)1010-4?
The DFN(PLP)package is a leadless package using an
electroforming sheet in place of lead frame.
This extremely compact package features increased
power dissipation and conversion to thinner type.
The name is representing by a combination of the body
size and the number of pins, i.e., DFN(PLP)1010-4
stands for the body size of 1.0mm×1.0mm and 4pins.
An environment-friendly, leadfree package with gold
plated contacts complies with the RoHS Directive.
The high-accuracy output delay time allows easy control of the start-up
sequence.
