Rev.1.1_03
The S-1002 Series is a high-accuracy voltage detector developed using CMOS technology. The detection voltage is fixed
internally with an accuracy of 1.0% (VDET(S) 2.2 V). It operates with current consumption of 500 nA typ.
Apart from the power supply pin, the detection voltage input pin (SENSE pin) is also prepared, so the output is stable even
if the SENSE pin falls to 0 V.
Two output forms Nch open-drain output and CMOS output are available.

Explanation of Terms
1. Detection voltage (VDET
)
The detection voltage is a voltage at which the output in Figure 18 or Figure 19 turns to "L". The detection voltage
varies slightly among products of the same specification. The variation of detection voltage between the specified
minimum (VDET min.) and the maximum (VDET max.) is called the detection voltage range (Refer to Figure 16).
Example: In the S-1002Cx18, the detection voltage is either one in the range of 1.778 V VDET 1.822 V.
This means that some S-1002Cx18 have VDET = 1.778 V and some have VDET = 1.822 V.
2. Release voltage (VDET
)
The release voltage is a voltage at which the output in Figure 18 or Figure 19 turns to "H". The release voltage
varies slightly among products of the same specification. The variation of release voltage between the specified
minimum (VDET min.) and the maximum (VDET max.) is called the release voltage range (Refer to Figure 17). The
range is calculated from the actual detection voltage (VDET) of a product and is in the range of VDET 1.03
VDET VDET 1.07.
Example: For the S-1002Cx18, the release voltage is either one in the range of 1.832 V VDET 1.949 V.
This means that some S-1002Cx18 have VDET = 1.832 V and some have VDET = 1.949 V.

Rev.1.1_03
3. Hysteresis width (VHYS
)
The 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 22 Timing Chart of S-1002 Series NA / NB Type" and "Figure
24 Timing Chart of S-1002 Series CA / CB Type"). Setting the hysteresis width between the detection voltage
and the release voltage, prevents malfunction caused by noise on the input voltage.
4. Feed-through current
The feed-through current is a current that flows instantaneously to the VDD pin at the time of detection and release
of a voltage detector. The feed-through current is large in CMOS output product, small in Nch open-drain output
product.
5. Oscillation
In applications where an input resistor is connected (Figure 20), taking a CMOS output (active "L") product for
example, the feed-through current which is generated when the output goes from "L" to "H" (at the time of release)
causes a voltage drop equal to [feed-through current] [input resistance]. Since the VDD pin and the SENSE pin
are shorted as in Figure 20, the SENSE pin voltage drops at the time of release. Then the SENSE pin voltage
drops below the detection voltage and the output goes from "H" to "L". In this status, the feed-through current stops
and its resultant voltage drop disappears, and the output goes from "L" to "H". The feed-through current is then
generated again, a voltage drop appears, and repeating the process finally induces oscillation.

2. SENSE pin
2. 1 Error when detection voltage is set externally
By connecting a node that was resistance-divided by the resistor (RA) and the resistor (RB) to the SENSE pin as
seen in Figure 25, the detection voltage can be set externally.
For conventional products without the SENSE pin, RA cannot be too large since the resistance-divided node must
be connected to the VDD pin. This is because a feed-through current will flow through the VDD pin when it goes
from detection to release, and if RA is large, problems such as oscillation or larger error in the hysteresis width may
occur.
In the S-1002 Series, RA and RB are easily made larger since the resistance-divided node can be connected to the
SENSE pin through which no feed-through current flows. However, be careful of error in the current flowing through
the internal resistance (RSENSE) that will occur.
Although RSENSE in the S-1002 Series is large (5 M min.) to make the error small, RA and RB should be selected
such that the error is within the allowable limits.
2. 2 Selection of RA and RB
In Figure 25, the relation between the external setting detection voltage (VDX) and the actual detection voltage
(VDET) is ideally calculated by the equation below.
RA
RB
VDX = VDET

··· (1)

However, in reality there is an error in the current flowing through RSENSE

When considering this error, the relation between VDX and VDET is calculated as follows.

As seen in equation (3), the smaller the resistance values of RA and RB compared to RSENSE, the smaller the error
rate becomes.
Also, the relation between the external setting hysteresis width (VHX) and the hysteresis width (VHYS) is calculated
by equation below. Error due to RSENSE also occurs to the relation in a similar way to the detection voltage.

2. 4 Precautions when shorting between the VDD pin and the SENSE pin
2. 4. 1 Input resistor
Do not connect the input resistor (RA) when shorting between the VDD pin and the SENSE pin.
A feed-through current flows through the VDD pin at the time of release. When connecting the circuit shown as
Figure 27, the feed-through current of the VDD pin flowing through RA will cause a drop in VSENSE at the time of
release.
At that time, oscillation may occur if VSENSE VDET
.

2. 4. 2 Parasitic resistance and parasitic capacitance
Due to the difference in parasitic resistance and parasitic capacitance of the VDD pin and the SENSE pin,
power may be applied to the SENSE pin first.
Note that an erroneous release may occur if this happens (refer to "2. 3 Power on sequence").
Caution In CMOS output product, make sure that the VDD pin input impedance does not become too
high, regardless of the above. Since a feed-through current is large, a malfunction may occur if
the VDD pin voltage changes greatly at the time of release.

2. 5 Malfunction when VDD falls
As seen in Figure 28, note that if the VDD pin voltage (VDD) drops steeply below 1.2 V when VDET VSENSE
VDET, erroneous detection may occur.
When VDD_Low 1.2 V, erroneous detection does not occur.
When VDD_Low 1.2 V, the more the VDD falling amplitude increases or the shorter the falling time becomes, the
easier the erroneous detection.
Perform thorough evaluation in actual application.

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 product of the S-1002 Series, the feed-through current flows at the time of detection and release. If
the VDD pin input impedance is high, malfunction may occur due to the voltage drop by the feed-through current
when releasing.
In CMOS output product, oscillation may occur if a pull-down resistor is connected and falling speed of the SENSE
pin voltage (VSENSE) is slow near the detection voltage when the VDD pin and the SENSE pin are shorted.
When designing for mass production using an application circuit described herein, the product deviation and
temperature characteristics of the external parts should be taken into consideration. ABLIC Inc. shall not bear any
responsibility for patent infringements related to products using the circuits described herein.
ABLIC Inc. claims no responsibility for any disputes arising out of or in connection with any infringement by
products including this IC of patents owned by a third party.

Application Circuit Examples
1. Microcomputer reset circuits
In microcomputers, when the power supply voltage is lower than the minimum operation voltage, an unspecified
operation may be performed or the contents of the memory register may be lost. When power supply voltage
returns to the normal level, the microcomputer needs to be initialized. Otherwise, the microcomputer may
malfunction after that. Reset circuits to protect microcomputer in the event of current being momentarily switched
off or lowered.
Using the S-1002 Series which has the low minimum operation voltage, the high-accuracy detection voltage and
the hysteresis width, reset circuits can be easily constructed as seen in Figure 35 and Figure 36.

2. Change of detection voltage
If there is not a product with a specified detection voltage value in the S-1002 Series, the detection voltage can be
changed by using a resistance divider or a diode, as seen in Figure 37 to Figure 40.
In Figure 37 and Figure 38, hysteresis width also changes.
