Operation
1. Basic operation: CMOS output (Active “L”)
(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 (“H”) at the output. Since the Nch transistor N1 in Figure 14 is OFF, the
comparator input voltage is CBA
DDCB RRR V)RR(
++
+ .
(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 BA
DDB RR VR
+
.
(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.
(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.
(5) When the VDD rises above +VDET (point B in Figure 15), the Nch transistor becomes OFF and the Pch transistor
becomes ON to provide VDD level at the output .

Explanation of Terms
1. Detection voltage (VDET), release voltage (+VDET)
The detection voltage (VDET) is a voltage at which the output 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 18).
Example: For the S-1000C15, the det ection voltage lies in the range of 1.485 (VDET) 1.515.
This means that some S-1000C15s have 1.485 V for VDET and some have 1.515 V.
The release voltage is a voltage at which the output turns to “H”. The release voltage varies slightly among product s of
the same specification. The variation of release voltages between the specified minimum (+VDET) Min. and the maximum
(+VDET) Max. is called the release voltage range (Refer to Figure 19). The range is calculed from the actual detection
voltage (VDET) of a product and is expressed by VDET × 1.03 +VDET VDET × 1.07.
Example: For the S-1000C15, the release volt age lies in the range of 1.530 (+VDET) 1.621.
This means that some S-1000C15s have 1.530 V for +VDET and some have 1.621 V.

2. Hysteresis widt h (VHYS)
The hysteresis width is the voltage difference betw een 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 prevents malfunction caused by
noise on input signal.
3. Through-type current
The through-type current refers to the current that flow s instantaneously at the time of detection and release of a voltage
detector. The through-type current is large in CMOS output products, small in Nch open-drain output products.
4. Oscillation
In applications where a resistor is connected to the voltage detector input (Figure 20), taking a CMOS active “L” product
for example, the through-type current w hich is generated when the output goes from “L” to “H” (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 “L” to “H”. The through-type current is then
generated again, a voltage drop appears, and repeating the process finally induces oscillation.

Precautions
If the input impedance is high, oscillation may occur due to the through-type current etc. In COMS output products,
impedance should not be connected to the input pin. In Nch open drain output products, input impedance is
recommended to be 800 Ω or less. However be sure to perform sufficient evaluation under the actual usage conditions for
selection, including evaluation of temperature characteristics.
In CMOS output products oscillation may occur when a pull-down resistor is used, and falling speed of the power supply
voltage (VDD) is slow near the detection voltage.
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 products on the circuits
described herein.
Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
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 24, 25 can be easily constructed with the help of the S-1000 series, that has low
operating voltage, a high-precision detection voltage and hysteresis.
