SCI7661 Series FUNCTIONAL DESCRIPTION Oscillator Voltage Multiplier The voltage multiplier uses the clock signal from the oscillator to double or triple the input voltage. This requires three external capacitors–two charge-pump capacitors between CAP1+ and CAP1– and CAP2+ and CAP2–, respectively, and a smoothing capacitor between VI and VO.
PAGE 35
SCI7661 Series TYPICAL APPLICATIONS Voltage Tripler with Regulator The following figure shows the circuit required to triple the input voltage, regulate the result and add a temperature gradient of –0.4%/°C. Note that the high input impedance of RV requires appropriate noise countermeasures. Converting a Voltage Tripler to a Voltage Doubler To convert this curcuit to a voltage doubler, remove capacitor C2 and short circuit CAP2– to VO.
PAGE 36
SCI7661 Series Serial Connection connection, however, this also raises the output impedance. In case of series connections, when connecting loads between the first stage VDD (or other potential of the second stage VDD or up) and the second stage VREG as shown in Fig. 2-13, be cautions about the following point.
PAGE 37
SCI7661 Series Simultaneous Voltage Conversion Using an External Gradient Combining a standard voltage tripler circuit with one for positive voltage conversion generates both –15 and 8.2V outputs from a single input, however, it also raises the output impedance. A voltage doubler generates –10 and 3.8V outputs. The SCI7661C0B/M0B offers three built-in temperature gradients— –0.1, –0.4 and –0.6%/°C.

SCI7654 Series • Input voltages The SCI7654 C0A/M0A is a CMOS process, chargepumping DC/DC converter and voltage regulator featuring the very high efficiency but low power consumption. An addition of four, three, or two external capacitors can generate four-, three- or two-time output voltage in negative direction than the input voltage. Also, the built-in voltage regulator can set any output voltage of DC/DC converter and can output the regulated voltage using two external resistances.

SCI7654 Series Voltage Converter The voltage converter, consisting of a boost control circuit and a voltage converter circuit, receives clocks from the clock generator circuit and boosts the input power voltage (VI) four, three or two times. During four-time boosting, however, the three-time and two- time boost outputs cannot be obtained simultaneously. Figure 2.4 gives the potential relationship during four-, three- and two-time boosting.
PAGE 48
SCI7654 Series Reference Voltage Circuit The SCI7654 has a built-in reference voltage circuit for voltage regulation. The regulated voltage (explained in the next “voltage regulator circuit” section) is set depending on the division ratio between this reference voltage and the external resistance. The reference voltage can be used to change the temperature coefficient at pins TC1 and TC2. One of four states can be selected as listed on Table 2.6.
PAGE 49
SCI7654 Series Figure 2.
PAGE 50
SCI7654 Series Changing the temperature coefficient: • The temperature coefficient of the regulated voltage depends on the temperature coefficient of the reference voltage (if the division ratio of setup resistors does not depend on the temperature). It is necessary to change the temperature coefficient using thermistors, resistors or others to set any other temperature coefficient of the regulated voltage. The following explains how to calculate the VREG voltage in temperature T.
PAGE 51
SCI7654 Series Power-off Control Function The SCI7654 has the power-off function and turns on or off each circuit function when control signals are entered in the POFF1 and POFF2 pins from an external system (such as microprocessor) as defined on Table 2.7. This power-off function can also cut the reactive current in parallel connection and other application circuits.

SCI7654 Series APPLICATION CIRCUIT EXAMPLES Four-time Booster and Regulator Figure 2.8 gives a wiring example of four-time booster and regulator that is the typical SCI7654 application. This example boosts the input voltage (VI) four times in negative direction, and outputs the regulated voltage at VREG pin. Figure 2.
PAGE 54
SCI7654 Series 4-time Booster Only the booster circuit operates, and it boosts the input voltage (VI) four times in negative direction and outputs it at the VO pin. As the regulator is not used, the voltage appearing at the VO pin may contain ripple components. Figure 2.9 gives a wiring example. Figure 2.

SCI7654 Series Positive Voltage Conversion The SCI7654 can also boost up a voltage to the positive potential using external diodes. In such case, however, the regulator function is unavailable. Figure 2.14 gives a wiring example for three-time positive boosting, and Figure 2.15 provides its electrical potential relationship. Figure 2.
PAGE 59
SCI7654 Series ◊ Output voltages • When diodes are used for voltage boosting, the characteristics of diodes directly affect on the voltage boosting characteristics. The forward voltage drop (VF) of diodes can reduce the booster output voltage. As the example of Figure 2.14 uses three diodes, the drop of “VF” voltage multiplied by three occurs. The booster output voltage is expressed by equation (5). To increase the |VO'| value, use the diodes having a smaller VF.

SCI7810Y Series DESCRIPTION OF FUNCTION SOT89-3pin 1 2 3 The SCI7810Y series products are the fixed type positive output voltage regulators. They employ the series regulation approach using CMOS transistors between the input and output for control of the output. The voltage divided by the built-in resistors R1 and R2 (VREG ) is fed back to the operational amplifier and compared against the reference voltage (Vref).

SCI7810Y Series EXAMPLES OF APPLIED CIRCUITS Variable Voltage Circuit 1 The SCI7810Y series consists of 3-pin regulators with fixed output voltage. Their output voltage, however, can be changed providing resistors externally as shown in Figure 3-5. In this case, the output voltage VO is determined by the following formula.

SCI7810Y Series When Higher Input Voltage is Needed When you want to apply an input voltage higher than the rating, add the regulator circuit in to the preceding stage so that the input voltage to the IC becomes less than the rating. See Figure 3-7. NPN transistor SCI7810Y VI VO Voltage Regulator Zener diode Figure 3-7 When Turning On or Off Output The SCI7810Y series products are constantly in the operation mode, so applying an input voltage generates the specified output voltage.

SCI7910Y Series R1 helps reduce the affect of ISS on VF. It is also required when ISS is lower than the diode bias current. For certain input voltages, a Zener diode with the reverse polarity can be used. Switching output SCI7910Y series devices are designed for continuous operation. An external switching circuit allows the regulated output to be switched ON and OFF. High Input Voltages A preliminary regulator circuit is required to bring the input voltage within the SCI7910Y series rated range.

SCI7630 Series In standby mode, the booster, including the crystal oscillator, is disabled (the switching transistor used to drive the inductor is turned OFF) and the built-in backup switch is turned ON, so that the input voltage at VI2 is output at VO. This enables the battery backup function. PS is pulled-up internally, so when standby mode is not required, the pin should be left open. VO circuit PWCR VI1 circuit VI1 RST Powering up The SCI7638 series are provided with a response compensation input.

SCI7630 Series FUNCTIONAL DESCRIPTION Basic Voltage Booster Operation TR1 switches ON and OFF at the frequency of the clock pulses from the crystal oscillator. When the transistor is ON, the circuit stores energy in L. When it is OFF, this energy flows through D to charge C. L VI1 D The output voltage regulator regulates the boosted output voltage. This voltage is determined by the level at point A between the two resistors connecting VO and GND.
PAGE 119
SCI7630 Series Powering up Ensure that VO is at least the minimum operating voltage (0.9V) before switching on the booster circuit. One way to do this is to connect a capacitor between PS and GND so that the chip connects VO to VI when the power is applied for the first time.

SCI7720Y Series PRECAUTIONS Short cut current on the SCI 7721 (CMOS output voltage detector) Since the SCI772Y series employs CMOS output, as an input voltage nears the detection voltage range, short cut current is flown between VDD and VSS. The short cut current is voltage sensitive, and approximately 2 mA flows at 5V level or so (our products are not check for short cut current after volume production has been started).
