S-87X Series 󰀁Operation

1.Reference Voltage Circuit

The reference voltage circuits operate all the time while voltage is appliedto VIN pin independently of VPF signal.2.Voltage Regulator

Figure 7 shows the voltage regulator circuit. The S-87X Series has a PchMOS 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 thestructure of the control transistor. Therefore, keep VOUT lower thanVIN+0.3 V.

The output voltage of the voltage regulator can be selected as follows :

2.6V to 5.8V

±2.4% (0.1V step)

VINVREF-+M1VOUTR1R2Figure 7 Voltage Regulator

NoteFor an application with a load current of less than 1 µA, the

leakage current of the control transistor M1 increases the outputvoltage.

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 incase of a short circuit. The output short current is internally limited to approx. 70 mA. Short-circuit protection circuit hasthree kinds characteristics according to VIN (input voltage) as shown in Figure 8.At 5-V Output:(a)VOUT(V)VIN/VOUT≥2.0(b)1.5≤VIN/VOUT<2.0VOUT(V)(c)VOUT(V)VIN/VOUT<1.5IOSImaxIOUT(mA)IOSFigure 8IOUT(mA)IOSIOUT(mA)Note:Use a voltage regulator under the specified power dissipation of

S-87X Series4.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 Fig. 9, when Vcd exceeds the reference voltage (Vref), the outputvoltage pin VOR changes from low to high level, providing delayoutput. When the voltage at VIN pin falls under the detection voltage (-VDET), the N2 transistor turns ON, therefore the charge of CD israpidly discharged and the voltage detector output (VOR) changesfrom high to low level without delay.

The external capacitor (CD) is charged with constant current, and ispractically independent of VIN voltage. Its delay time (tpd) isexpressed by the following equation:

tpd (ms)=Delay coefficient (3.18 min., 5.74 typ., 8.73 max.)×CD (nF)Note•Unless an output delay is needed, keep CD pin open.

Do not apply external voltage other than ground potential toCD pins, which may cause IC breakdown.

•When designing your printed-circuit board layout, take carethat 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 only195 nA, CD to impedance is high.

5.Voltage Detection Circuit

The built-in voltage detection circuit (Nch opendrain type) is equivalent to our S-808/809 Series voltage detectors. A pull-upresistor of about 100 kΩ is required for output. Since the comparator power of this circuit is supplied from VIN pin, this circuitoperates 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%

(0.1V step)

ICN2Vcd+-VrefVORCDFigure 9 Delay

In the S-87XXXXF Series, the release voltage (+VDET) accuracy is±1.1%. So, it responds to the application for overchargedetection of lithium-ion battery packs.

In the S-87XXXXE Series, 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 beaccurately monitored by connecting the SENSE pin to the input power supply. Also, when a drop in the SENSE pin inputvoltage is detected, the voltage detector generates a reset signal. At the same time, it powers off the voltage regulator.Notes:

•As shown in Figure 11, when connecting VOR output to VPF pin in the S-87XXXXC Series or connecting SENSE pin to VIN pin in the S-87XXXXE Series, the following phenomena occur if RIN is connected between input voltage and VIN pin. Be careful.

󰀁At the time of voltage detection, the voltage regulator is shutdown and load current is cut. Therefore, VIN

voltage increases by ∆VIN= IIN×RIN, where the current flowing into RIN is set to IIN. Hence, if ∆VIN exceedshysterisis width Vhys, oscillation starts immediately after detection and continues. It is necessary to set∆VIN less than Vhys.

󰀂At the time of voltage release, the voltage regulator is powered on and load current flows. Therefore, if

∆VIN exceeds hysterisis width Vhys, oscillation starts immediately after release and continues. It isnecessary to set ∆VIN less than Vhys. Also at the time of voltage release, the rush current to charge output

HIGH WITHSTAND-VOLTAGE VOLTAGE REGULATOR WITH RESET FUNCTION

S-87X Series capacitor Cout flows. Hence, oscillation momentarily starts until the output of regulator Vout rises highenough even though ∆VIN is set less than Vhys. But Short-circuit protection circuit controls the rush currentless than Imax on fig.8. If this momentary oscillation is a problem in your applicaion, setting RIN less thanVhys/Imax prevents oscillation.

If a drop in VIN voltageoccurs due to load current or rush current to be charged to the output capacitor when load current or the voltageregulator is powered on at the time of release, set VIN to 2.0 V or more.

•Also, in the S-87XXXXE Series, when sharply increasing only VIN pin voltage at 1 ms/V or less, with the SENSE pinfixed to -VDET≥ VSENSE ≥ -VDET-2V, a release pulse is output to the output pin of voltage detector. Be careful. In thiscase, this release pulse is removed by setting the time constant of VOR pin 20ms 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 releasevoltage at the detect condition, if sharply increasing only VIN pin voltage at 1 ms/V or less, the output of the detectorturns to the release condition. If this action is a problem in your system, please connect SENSE pin to VIN pin.

6.Shutdown Circuit (S-87XXXXC/E Series)

When VPF pin goes low (0.4 V or less) in the S-87XXXXC Series or at the time of voltage detection in the S-87XXXXE series,current for the voltage regulator is shut down, with the current consumption (excluding the current which flows through thepull-up resistor) lowered to 3.5 µA or less.

During shutdown, the M1 transistor in the voltage regulator shown in the Figure 6 is off and VOUT pin is pulled down by R1and R2, whose value (R1+R2) is 5MΩ¶ to 10MΩ¶. Input current of VPF pin is 0.1µA or less.

Notes•The output voltage may not become 0 V if a load making IOUT under 50µA is connected during shutdown..

•DO NOT keep VPF pin floating state or in medium potential (between low and high levels). Otherwise a through-type current occurs.

S-87X Series󰀁Transient Response

An undershoot or an overshoot may occur in the output voltage of the voltage regulator if input voltage or load current fluctuatestransiently. If an undershoot is large, the voltage detector operates to output reset signal in the S-87XXXXB Series in which thevoltage 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 Response due to Input Voltage Ffluctuation

Input voltage fluctuation differs depending on the types of the signal applied: type Ι which is a rectangular wave between(VOUT + 1) V and 10 V, and type ΙΙ which is a rectangular wave from 0 V to 10 V (see Figure 16). The ringing waveforms andparameter dependency of each type are described below. The measuring circuit is shown in Figure 17 for reference, .
