Caution In the S-87xxxxB/S-87xxxxG Series, when the output voltage of the voltage regulator is
close to the detection voltage of the voltage detector, the transient response of the
voltage regulator may cause false detection. Please take transient response into
account when deciding voltages.

„ Operation
1. Reference voltage circuit
The reference voltage circuit operates all the time when the voltage is applied to VIN pin and is not
affected by the VPF signal.
2. Voltage regulator
Figure 18 shows the voltage regulator circuit. The S-87x Series has a Pch MOS transistor as the output
control transistor.
Reverse current may break IC if VOUT potential is higher than VIN, because a parasitic diode is formed
between VIN and VOUT due to the structure of the control transistor. Therefore, keep VOUT lower than
VIN+0.3 V.
The output voltage of the voltage regulator can be selected as follows:
2.5 V to 5.8 V±2.4 % (0.1 V step)

Caution For an application with a load current of less than 1 μA, the leakage current of the control
transistor M1 increases the output voltage.
3. Short-circuit protection circuit
The S-87x Series has a built-in short-circuit protection circuit to protect the element from break caused by
a large current in case of a short circuit. The output short current is internally limited to approx. 70 mA.
Short-circuit protection circuit has three kinds characteristics according to input voltage (VIN) as shown in
Figure 19 to 21.

4. Delay circuit
The delay circuit outputs voltage detector output (VOR) with delay after the voltage at VIN pin has become
release voltage (+VDET) at the rising of VIN pin.
In Figure 22, when Vcd exceeds the reference voltage (Vref), the output voltage pin detection voltage
output (VOR) changes from low to high level, providing delay output. When the voltage at VIN pin falls
under the detection voltage (−VDET), the N2 transistor turns ON, therefore the charge of the external
capacitor (CD) is rapidly discharged and the voltage detector output (VOR) changes from high to low level
without delay.
The external capacitor (CD) is charged with constant current, and is practically independent of VIN voltage.
Its delay time (tpd) is expressed by the following equation:
tpd (ms)=Delay coefficient (3.18 min., 5.74 typ., 8.73 max.)×CD (nF)

Caution 1. Unless an output delay is needed, keep CD pin open. Do not apply external voltage
other than ground potential to CD pin, which may cause IC breakdown.
2. When designing your printed-circuit board layout, take care that no leakage current
flows to the external capacitor (CD), otherwise the correct delay time may not be
obtained. Because the value of the constant current source (IC) is only 195 nA, CD to
impedance is high.

5. Voltage detection circuit
The built-in voltage detection circuit (Nch opendrain type) is equivalent to our S-808 Series/S-809 Series
voltage detectors. A pull-up resistor of about 100 kΩ is required for output. Since the comparator power
of this circuit is supplied from VIN pin, this circuit operates while voltage is applied to VIN pin.
The detection voltage of the voltage detector can be selected as follows:
2.1 V to 11.3 V±2.4 % (0.1 V step)
In the F type, the release voltage (+VDET) accuracy is ±1.1 %. So, it responds to the application for
overcharge detection of lithium-ion battery packs.
In the E type, the input voltage monitoring pin of the voltage detector is externally connected as the
SENSE pin. Because this pin is configured by a resistor only, temporary current such as a through-type
current does not flow. Consequently even when resistor (RIN) is inserted between input power supply and
VIN pin, the input power voltage can be accurately monitored by connecting the SENSE pin to the input
power supply. Also, when a drop in the SENSE pin input voltage is detected, the voltage detector
generates a reset signal. At the same time, it powers off the voltage regulator.
Caution 1. As shown in Figure 23 to 25, when connecting VOR output to VPF pin in the C type or
connecting SENSE pin to VIN pin in the E type, the following phenomena occur if
resistor (RIN) is connected between input voltage and VIN pin. Be careful.
(1) At the time of voltage detection, the voltage regulator is shutdown and load
current is cut. Therefore, VIN pin voltage increases by ΔVIN=IIN×RIN, where the
current flowing into RIN is set to IIN. Hence, if ΔVIN exceeds hysterisis width
(VHYS), oscillation starts immediately after detection and continues. It is
necessary to set ΔVIN less than VHYS.
(2) At the time of voltage release, the voltage regulator is powered on and load
current flows. Therefore, if ΔVIN exceeds hysterisis width (VHYS), oscillation
starts immediately after release and continues. It is necessary to set ΔVIN less
than VHYS. Also at the time of voltage release, the rush current to charge output
capacitor (COUT) flows. Hence, oscillation momentarily starts until the output of
regulator (VOUT) rises high enough even though ΔVIN is set less than VHYS. But
Short-circuit protection circuit controls the rush current less than IMAX on
Figure 19 to 21. If this momentary oscillation is a problem in your applicaion,
setting RIN less than VHYS/IMAX prevents oscillation.

2. In the E type, the minimum operating voltage becomes 2.0 V as VIN voltage. If a drop
in VIN voltage occurs due to load current or rush current to be charged to the output
capacitor when load current or the voltage regulator is powered on at the time of
release, set VIN to 2.0 V or more.
3. Also, in the E type, when sharply increasing only VIN pin voltage at 1 ms/V or less,
with the SENSE pin fixed to −VDET≥VSENSE≥−VDET−2 V, a release pulse is output to the
output pin of voltage detector. Be careful. In this case, this release pulse is removed
by setting the time constant of VOR pin 20 ms or more with capacitance and pull-up
resistance. In addition, when the voltage of SENSE pin is fixed to between the
detection voltage and the release voltage at the detect condition, if sharply increasing
only VIN pin voltage at 1 ms/V or less, the output of the detector turns to the release
condition. If this action is a problem in your system, please connect SENSE pin to
VIN pin.

6. Shutdown circuit (C/E/G type)
When VPF pin goes low (0.4 V or less) in the C/G type or at the time of voltage detection in the E type
current for the voltage regulator is shut down, the current consumption (excluding the current which flows
through the pull-up resistor) lowers to 3.5 μA or less.
During shutdown, the M1 transistor in the voltage regulator shown in the Figure 17 is off and VOUT pin is
pulled down by R1 and R2, whose value (R1+R2) is 5 MΩ to 10 MΩ. Input current of VPF pin is 0.1 μA or
less.
Caution 1. The output voltage may not become 0 V when the load which makes IOUT under 1 μA is
connected during shutdown.
2. DO NOT keep VPF pin floating state or medium potential (between low and high
levels). Otherwise through-type current flows.

„ Transient Characteristics
An undershoot or an overshoot may occur in the output voltage of the voltage regulator if input voltage or
load current fluctuates transiently. If an undershoot is large, the voltage detector operates to output reset
signal in the B type in which the voltage detector detects the output voltage of the regulator. If an overshoot
is large, the load circuit is adversely affected. Therefore it is important to determine the capacitor value so as
to minimize undershoot and overshoot.
1. Line: Transient characteristics due to input voltage fluctuation
Input voltage fluctuation differs depending on the types of the signal applied: type 1 which is a rectangular
wave between (VOUT+1) V and 10 V, and type 2 which is a rectangular wave from 0 V to 10 V. (Refer to
Figure 26 to 27) The ringing waveforms and parameter dependency of each type are described below.
The measuring circuit is shown in Figure 28 for reference.

2. Load transient response characteristics due to load current fluctuation
An overshoot and an undershoot are caused in the output voltage if the load current is changed from
50 μA to 40 mA while the input voltage is kept constant. Figure 31 shows the output voltage fluctuation
due to a change in the load current. The measuring circuit is shown in Figure 32 for reference. The
latter half of this section describes ringing waveform and parameter dependency.

1. Microcomputer power supply and reset circuit
To construct a microcomputer power supply and a reset circuit using conventional ICs, a voltage regulator
IC, a voltage detector IC, a delay time generation circuit and others are required. The A/B type allows
you to make these circuits without these ICs, and the delay time is variable.

3. Power supply for lithium-ion battery pack
When the lithium-ion battery goes down to the overdischarge voltage, the built-in voltage detector powers
OFF the voltage regulator, and at the same time it transmits the RESET signal to the microcomputer. R1,
C1, R2 and C2 are attached to eliminate the voltage exceeding the absolute maximum ratings of charger.
C3 is attached to give a delay and to release the RESET signal after power supply voltage for
microcomputer (VOUT) rises high enough.
