ULTRA-SMALL PACKAGE HIGH-PRECISION VOLTAGE DETECTOR
WITH DELAY CIRCUIT (EXTERNAL DELAY TIME SETTING)
S-809xxC Series
The S-809xxC Series is a high-precision voltage
detector developed using CMOS process. The
detection voltage is fixed internally with an accuracy of
±2.0 %. A time delayed reset can be accomplished
with the addition of an external capacitor. Two output
forms, Nch open-drain and CMOS output, are
available.
Features
• Ultra-low current consumption
1.0 μA typ. (Detection voltage ≤ 1.4 V, at VDD=2.0 V)
1.1 μA typ. (Detection voltage ≥ 1.5 V, at VDD=3.5 V)
• High-precision detection voltage ±2.0 %
• Operating voltage range
• Hysteresis characteristics
• Detection voltage
0.7 V to 10.0 V
5 % typ.
1.3 V to 6.0 V (0.1 V step)
Nch open-drain output (Active Low)
CMOS output (Active Low)
• Output forms
• Lead-free products
Applications
• Power supply monitor for portable equipment such as notebook PCs, digital still cameras, PDAs and
cellular phones
• Constant voltage power monitor for cameras, video equipment and communication equipment
• Power monitor and reset for CPUs and microcomputers

Operation
1. Basic Operation: CMOS Output (Active Low)
1-1. When the power supply voltage (VDD) is higher than the release voltage (+VDET), the Nch transistor is
OFF and the Pch transistor is ON to provide VDD (high) at the output. Since the Nch transistor N1 in
(RB + RC)• VDD
RA + RB + RC
Figure 14 is OFF, the comparator input voltage is
.
1-2. When the VDD goes below +VDET, the output provides the VDD level, as long as the VDD remains above
the detection voltage −VDET. When the VDD falls below −VDET (point A in Figure 15), the Nch
transistor becomes ON, the Pch transistor becomes OFF, and the VSS level appears at the output. At
this time the Nch transistor N1 in Figure 14 becomes ON, the comparator input voltage is changed to
RB • VDD
RA + RB
.
1-3. When the VDD falls below the minimum operating voltage, the output becomes undefined, or goes to
the VDD when the output is pulled up to the VDD
.
1-4. The VSS level appears when the VDD rises above the minimum operating voltage. The VSS level still
appears even when the VDD surpasses −VDET, as long as it does not exceed the release voltage
+VDET
.
1-5. When VDD rises above +VDET (point B in Figure 15), the Nch transistor becomes OFF, and the Pch
transistor becomes ON, and VDD appears at the output after the delay time (tD) counted by the delay
circuit.

2. Delay Circuit
The delay circuit delays the output signal from the time at which the power voltage (VDD) exceeds the
release voltage (+VDET) when VDD is turned on. The output signal is not delayed when the VDD goes below
the detection voltage (−VDET) (Refer to Figure 15). The delay time (tD) is determined by the time constant
of the built-in constant current (approx. 100 nA ) and the attached external capacitor (CD), and calculated
from the following equation.
tD (ms)=Delay coefficient×CD (nF)
Delay coefficient: (25°C)
Detection voltage −VDET ≤ 1.4 V
Detection voltage −VDET ≥ 1.5 V

Caution 1. When the CD pin is open, a double pulse shown in Figure 16 may appear at release. To
avoid the double pulse, attach 20 pF or larger capacitor to the CD pin. Do not apply
voltage to the CD pin.
VOUT
time
Figure 16
2. Print circuit board layout should be made in such a way that no current flows into or
flows from the CD pin since the impedance of the CD pin is high, otherwise correct
delay time cannot be provided.
3. There is no limit for the capacitance of the external capacitor (CD) as long as the leakage
current of the capacitor can be ignored against the built-in constant current value.
Leakage current causes deviation in delay time. When the leakage current is larger
than the built-in constant current, no release takes place.

Technical Terms
1. Detection Voltage (−VDET), Release Voltage (+VDET
)
The detection voltage (−VDET) is a voltage at which the output turns to low. This detection voltage varies
slightly among products of the same specification. The variation of detection voltage between the
specified minimum (−VDET) Min. and maximum (−VDET) Max. is called the detection voltage range (Refer to
Figure 19).
Example: For the S-80927CN, detection voltage lies in the range of 2.646≤(−VDET) ≤ 2.754.
This means that some S-80927CNs have 2.646 V for −VDET and some have 2.754 V.
The release voltage (+VDET) is a voltage at which the output turns to high. This release voltage varies
slightly among products of the same specification. The variation of release voltage between the specified
minimum (+VDET) Min. and maximum (+VDET) Max. is called the release voltage range (Refer to Figure 20).
The range is calculated from the actual detection voltage (−VDET) of a product and is expressed by
−VDET×1.03≤+VDET≤−VDET×1.08 for S-80913 to S-80914, and by −VDET×1.03≤+VDET≤−VDET ×1.07 for S-
80915 to S-80960.
Example: For the S-80927CN, the release voltage lies in the range of 2.725≤(+VDET)≤ 2.947.
This means that some S-80927CNs have 2.725 V for +VDET and some have 2.947 V.

Remark Although the detection voltage and release voltage overlap in the range of 2.725 V to 2.754 V,
+VDET is always larger than −VDET
.
2. Hysteresis Width (VHYS
)
Hysteresis width is the voltage difference between the detection voltage and the release voltage (The
voltage at point B−The voltage at point A=VHYS in Figure 15). The existence of the hysteresis width avoids
malfunction caused by noise on input signal.
3. Delay Time (tD)
Delay time is a time internally measured from the instant at which input voltage to the VDD pin exceeds
the release voltage (+VDET) to the point at which the output of the OUT pin inverts. The delay time
changes according to the external capacitor (CD).

4. Through-type Current
The through-type current refers to the current that flows instantaneously at the time of detection and
release of a voltage detector. The through-type current is large in CMOS output products, and small in Nch
open-drain output products.

5. Oscillation
In applications where a resistor is connected to the voltage detector input (Figure 22), taking a CMOS
active low product for example, the through-type current, which is generated when the output goes from
low to high (release) causes a voltage drop equal to [through-type current] × [input resistance] across the
resistor. When the input voltage drops below the detection voltage (−VDET) as a result, the output voltage
goes to low level. In this state, the through-type current stops and its resultant voltage drop disappears,
and the output goes from low to high. The through-type current again generated, a voltage drop appears,
and repeatiing the process finally induces oscillation.

Precautions
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in
electrostatic protection circuit.
• In CMOS output products of the S-809xxC series, the through-type current flows at the detection and the
release. If the input impedance is high, oscillation may occur due to the voltage drop by the through-type
current during releasing.
• When designing for mass production using an application circuit described herein, the product deviation
and temperature characteristics should be taken into consideration. SII shall not bear any responsibility
for the patents on the circuits described herein.
• SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of
the products including this IC upon patents owned by a third party.

Application Circuit Examples
1. Microcomputer Reset Circuits
If the power supply voltage to a microcomputer falls below the specified level, an unspecified operation
may be performed or the contents of the memory register may be lost. When power supply voltage
returns to normal, the microcomputer needs to be initialized before normal operations can be done.
Reset circuits protect microcomputers in the event of current being momentarily switched off or lowered.
Reset circuits shown in Figures 27 to 28 can be easily constructed with the help of the S-809xxC Series
that has a low operating voltage, a high-precision detection voltage, hysteresis and the reset circuits.

2. Change of Detection Voltage
In Nch open-drain output products of the S-809xxC Series, detection voltage can be changed using
resistance dividers or diodes as shown in Figures 29 to 30. In Figure 29, hysteresis width also changes.

Caution If RA and RB are large, the hysteresis
width may also be larger than the value
given by the above equation due to
through- type current (which flows
slightly in an Nch open-drain products).
