VOLTAGE DETECTOR
WITH OUTPUT DELAY
RN5VD SERIES
APPLICATION MANUAL
NO.EA-027-0006
VOLTAGE DETECTOR
WITH OUTPUT DELAY
1
OUTLINE
The RN5VD Series are voltage detector ICs with output delay functions and high detector threshold
accuracy and ultra-low supply current by CMOS process, which can be operated at an extremely low volt-
age and is used,for instance, for system reset.
Each of these ICs consists of a voltage reference unit, a comparator, resistors for voltage detection, an
output driver, a hysteresis circuit and an output delay generator. The detector threshold is fixed with high
accuracy in the IC and requires no adjustment.
The RN5VD Series are operable by a lower voltage than that for the R
×5VL Series, and can be driven
by a single battery.
Two output types, Nch open drain type and CMOS type, are available. Since the package for these ICs
are SOT-23-5(Mini-mold)package, high density mounting of the ICs on board is possible.

SELECTION GUIDE
The detector threshold, the output type, the packing type, and the taping type of RN5VD Series can be desig-
nating at the user's request by specifying the part number as follows :
For example, the Product with Detector Threshold 3.5V, Output Type Nch Open Drain and Taping Type TR,
is designated by Part Number RN5VD35AA-TR.
Code
a
Setting Detector Threshold (–V
DET
) :
Stepwise setting with a step of 0.1V in the range of 0.9V to 6.0V is possible.
b
Designation of Output Type

Absolute Maximum ratings are threshold limit values that must not be exceeded even for an instant under any
conditions. Moreover, such values for any two items must not be reached simultaneously. Operation above
these absolute maximum ratings may cause degradation or permanent damage to the device. These are stress
ratings only and do not necessarily imply functional operation below these limits.
