Touch Tester - Operation,Installation and Calibration Instructions
Pass Range 750K Ohms to 10 Megohm 120VAC Operation
Made in America
Environmental Conditions
• Suitable for indoor use only at altitudes not exceeding 6500 ft. (2Km) • Temperature range of 41°F (5°C) to 104°F (40°C) • Maximum relative humidity of 80% up to 88°F (31°C) decreasing linearly to 50% @ 104°F (40°C) • Pollution degree 2 per IEC 664 • Installation Category II CAUTION: If this equipment is used in a manner not specified by the manufacturer, the protection provide by the equipment may be impaired.
If desired, the Touch Tester will augment the visual “test good” indicator with an audible signal. In the “on” position, the tester will beep when the green “test good” LED is on, thereby allowing the operator to frequently test the wristband and cord without having to look at the tester. To enable/disable the signal, a slide switch is accessible through the hole on the back of the unit. First, unplug the power supply. Actuate the switch with a small probing tool, being careful to avoid internal damage.

description
This series of fixed negative-voltage integrated-circuit SOT-89 voltage regulators is designed for a wide range of applications. These include on-card regulation for 79L12CPK COMMON INPUT OUTPUT elimination of noise and distribution problems associated with single-point regulation. In addition, they can be used to control series pass elements to make high-current voltage-regulator circuits. One of these regulators can deliver up to 100 mA of output current. The internal current-limiting and thermal-shutdown features make them essentially immune to overload. When used as a replacement for a zener-diode and resistor combination, these devices can provide ef fective improvement in output impedance of two orders of magnitude, with lower bias current.

The reference voltage can be used as the power supply for internal circuits, or as a reference voltage, and can also be accessed externally via the V REF pin (pin 2).2.2 OscillatorThe oscillator self-oscillates if a timing resistor is attached to the R T pin (pin 3). This oscillator waveform is input to the inverted input pins (channel 1 and 2) or non-inverted input pin (channel 3) of the three PWM comparators to determine the oscillation frequency.2.3 Under Voltage Lock-out CircuitThe under voltage lock-out circuit prevents malfunctioning of the internal circuits when the supply voltage is low, such as when the supply voltage is first applied, or when the power supply is interrupted. When the voltage is low, the three output transistors are cut off at the same time.2.4 Error AmplifiersThe non-inverted input pins of the error amplifiers E/A1, E/A2, and E/A3 are connected internally to 0.3 V (the input threshold voltages are all 0.3 V (TYP.)). The circuits of the error amplifiers E/A1, E/A2, and E/A3 are exactly the same. The first stage of the error amplifier is a P-channel MOS transistor input.2.5 PWM ComparatorsThe output ON duty is controlled according to the outputs of the error amplifiers and the voltage input to the Dead Time Control pin (fixed internally for channel 1).A triangular waveform is input to the inverted pin, and the error amplifier output and Dead Time Control pin voltage (fixed internally for channel 1) are input to the non-inverted pins of the PWM comparators for channel 1 and channel 2. Therefore, the output transistor ON period is the period when the triangular waveform is lower than the error amplifier output and Dead Time Control pin voltage (fixed internally for channel 1).Channel 3 is the logical inverse of channel 1 and channel 2. Consequently, the triangular waveform is input to the non-inverted input pin, and the error amplifier output and Dead Time Control pin voltage are input to the inverted input pins of the PWM comparator for channel 3. Therefore, the transistor ON period is the period when the triangular waveform is higher than the error amplifier output and Dead Time Control pin voltage (refer to Timing Charts).2.6 Timer Latch-Method Short Circuit Protection CircuitWhen the outputs of the converters for each channel drop, the FB outputs of the error amplifiers of those outputs go high (FB3 output goes low). If the FB output exceeds the timer latch input detection voltage (V TH = 1.9 V) (FB3 output goes lower than the timer latch input detection voltage (V TH = 0.63 V)), then the output of the SCP comparator goes low, and Q1 goes off.When Q1 turns OFF, the constant-current supply charges C DLY via the DL Y pin. The DL Y pin is internally connected to a flip-flop. When the DL Y pin voltage reaches the UV detection voltage (V UV = 0.8 V (TYP.)), the output Q of the flip-flop goes low, and the output stage of each channel is latched to OFF (refer to Figure 2-1 Block Diagram).The logic of channels 1 and 2 is reverse to that of channel 3. Consequently, an inverter circuit is inserted between the FB output of channels 1 and 2, and SCP comparator input.Make the power supply voltage briefly less than the reset voltage (V CCR, 1.0 V TYP.) to reset the latch circuit when the short-circuit protection circuit has operated.2.7 Output CircuitThe output circuit has an N-channel open-drain output providing an output withstand voltage of 30 V (absolute maximum rating), and an output current of 21 mA (absolute maximum rating).3.NOTES ON USE3.1 Setting the Output VoltageFigure 3-1 illustrates the method of setting the output voltage. The output voltage is obtained using the formula shown in the figure.The input threshold value of the error amplifier is 0.3 V (TYP .) for all the error amplifiers, E/A 1, E/A 2, and E/A 3.Therefore, select a resistor value that gives this voltage.Figure 3-1 Setting the Output Voltage(1) When setting a positive output voltage using error amplifier E/A 1.(2) When setting a positive output voltage using error amplifier E/A 2.R R VR R V(3) When setting a negative output voltage using error amplifier E/A 3.3.2 Setting the Oscillation FrequencyChoose R T according to the oscillation frequency (f OSC ) vs timing resistor (R T ) characteristics (refer to Typical Characteristics Curves f OSC vs R T ). The formula below (3-1) gives an approximation of f OSC . However, the result of formula 3-1 is only an approximation, and the value must be confirmed in actual operation, especially for high-frequency operation.f OSC [Hz] ≅ 1.856 x 109/R T [Ω] (3-1)3.3 Preventing Malfunction of the Timer Latch-Method Short Circuit Protection CircuitThe timer latch short-circuit protection circuit operates when the error amplifier outputs of channel 1 or channel 2 (pin 7and 10) exceed approximately 1.9 V , or when the error amplifier output of channel 3 (pin 14) goes below approximately 0.63 V , and cuts off the output. However, if the rise of the power supply voltage is fast, or if there is noise on the DL Y pin (pin 5), the latch circuit may malfunction and cut the output off.T o prevent this, keep the wiring impedance between the DL Y pin and the GND pin (pin 4) low, and avoid applying noise to the DL Y pin.R 1R 2OUT3.4 Connecting Unused Error AmplifiersWhen the unused circuit of the three control circuits provided internally is error amplifier E/A2, connect the circuit in such a way as to make sure that the output of the error amplifier is low. When the unused circuit is error amplifier E/A3, connect the circuit in such a way as to make sure that the output of the error amplifier is high. In the case of error amplifier E/A1, the Dead Time Control pin is fixed internally, so be sure to always use this amplifier.Figure 3-2 shows examples of how to connect unused error amplifiers.Figure 3-2 Examples of Connecting Unused Error Amplifiers(1) Error amplifier E/A2(2) Error amplifier E/A33.5ON/OFF Control3.5.1 Channel 1 (for step-up)The ON/OFF signal control method of the output oscillation of channel 1 is to input the ON/OFF signal from ON 1 as shown in Figure 3-3. For channel 1, soft start or timer latch (SCP) is internally selected. Soft start is executed when the first start signal is input. When the end of soft start is detected, the soft start select switch is turned OFF and the timer latch circuit operates.Figure 3-3 ON/OFF Control (channel 1 for step-up)(1) When ON 1 is high: OFF statusQ 11: ON → DL Y pin: Low level → Output duty of PWM comparator: 0 %D 11: ON → I I1 pin: High level → FB 1 output: Low level(2) When ON 1 is low: ON status (start up)Q 11: OFF → C DLY is charged in the sequence of [V REF → R 1 → SW → DL Y pin → C DLY ] → Soft start D 11: OFF → I I1 pin: Low level → FB 1 output: High level(3) When ON 1 goes high again after start up (SW: OFF): OFF status Q 11: ON → DL Y pin: Low level (Nothing happens because SW is OFF .)D 11: ON → I I1 pin: High level → FB 1 output: Low level → PWM comparator output duty: 0 %→ Converter output voltage (V O1) drops.Caution Even if start up is executed by making ON 1 low again after (3), soft start is not executed because thesoft start select switch (SW) remains OFF. To execute soft start of channel 1 again, drop V CC to 0 V once.ON 13.5.2Channel 2 (for step-up)The ON/OFF signal control method of the output oscillation of channel 2 is to input the ON/OFF signal from ON 2 as shown in Figure 3-4. The PWM converter can be turned ON/OFF by controlling the level of the DTC 2 pin. However, it is necessary to keep the level of the FB 2 output low (the SCP comparator input high) so that the timer latch does not start when the PWM converter is OFF . In this circuit example, the FB 2 output level is controlled by controlling the level of the I I2pin.Figure 3-4 ON/OFF Control (channel 2: step-up)(1) When ON 2 is high: OFF statusQ 21: ON → DTC 2 pin: Low level → Output duty of PWM comparator: 0 %D 21: ON → I I2 pin: High level → FB 2 output: Low level → SCP comparator output: High level → Timer latch stops.(2) When ON 2 is low: ON statusQ 21: OFF → C 21 is charged in the sequence of [V REF → R 23 → C 21] → DTC 2 pin voltage rises → Soft start D 21: OFF → I I2 pin: Low level → FB 2 output: High level → SCP comparator output: Low level → Q 1 is OFF→ Charging C DLY starts (timer latch start).Caution Keep the low-level voltage of the DTC 2 pin within 1.2 V and the high-level voltage of the I I2 pin at0.3 V or higher. The maximum voltage that is applied to the I I2 pin must be equal to or lower than V REF .ON 2C DLY3.5.3Channel 3 (for inverted output)The ON/OFF signal control method of the output oscillation of channel 3 is to input the ON/OFF signal from ON 3 as shown in Figure 3-5. The PWM converter can be turned ON/OFF by controlling the level of the DTC 3 pin. However, it is necessary to keep the level of the FB 3 output high so that the timer latch does not start when the PWM converter is OFF .In this circuit example, the FB 3 output level is controlled by controlling the level of the I I3 pin.Because channel 3 supports an inverted converter, its PWM comparator logic is different from that of channels 1 and 2.Figure 3-5 ON/OFF Control (channel 3: for inverted output)(1) When ON 3 is high: OFF statusQ 31: ON → Q 32: ON → DTC 3 pin: High level → Output duty of PWM comparator: 0 %Q 33: ON → I I3 pin: Low level → FB 3 output: High level → SCP comparator output: High level → Q 1 is ON.→ Timer latch stops.(2) When ON 3 is low: ON statusQ 31: OFF → Q 32 is OFF . → C 31 is charged in the sequence of [V REF → C 31 → R 34] → DTC 3 pin voltage drops.→ Soft startQ 33: OFF → I I3 pin: High level → FB 3 output: Low level → SCP comparator output: Low level → Q 1: OFF→ Charging C DLY starts (timer latch start).Caution Keep the high-level voltage of the DTC 3 pin at 1.6 V or higher and the low-level voltage of the I I3 pin within 0.3 V . The maximum voltage that is applied to the I I3 pin must be equal to or lower than V REF .ON 3DLY3.6 Maximum Duty LimitChannel 1 is switched internally between Soft Start and Timer Latch. For this reason, the DTC voltage is fixed internally, and the maximum duty is limited to 85%.The DTC voltage for channel 2 and channel 3 can be set externally, so the maximum duty is not limited.3.7 Notes on Actual Pattern WiringWhen actually carrying out the pattern wiring, it is necessary to separate control-related grounds and power-related grounds, and make sure that they do not share impedances as far as possible. In addition, make sure the high-frequency impedance is lowered using capacitors and other components to prevent noise input to the V REF pin.Data Sheet G13418EJ3V0DS00214.APPLICATION EXAMPLE4.1Application ExampleFigure 4-1 shows an example circuit for obtaining ±5 V/50 mA and +12 V/50 mA from a +3 V power supply.Figure 4-1 Chopper-Method/Inverting-Type Switching RegulatorC H 2V O 2 = +5 V I O = 50 m AC O MC H 3V O 3 = −5 V I O = 50 m AC H 1V O 1 = +12 V I O = 50 m A4.2 List of External PartsThe list below shows the external parts.Table 4-1 List of External PartsSymbol Parameter Function Part number Maker RemarkC1168 µ F Output capacitor20SA68M SANYO OS-CON, SA series D11Schottkey diode D1FS4SHINDENGENL1147 µ H Choke inductor636FY-470M TOKO D73F seriesQ11Switching transistor2SD2403NECQ12Buffer transistor2SA812NECQ13Buffer transistor2SC1623NECD12Switching diode1SS220NECQ14Transistor for switch2SK2158NECC2168 µ F Output capacitor20SA68M SANYO OS-CON, SA series D21Schottkey diode D1FS4SHINDENGENL2147 µ H Choke inductor636FY-470M TOKO D73F seriesQ21Switching transistor2SD2403NECQ22Buffer transistor2SA812NECQ23Buffer transistor2SC1623NECD22Switching diode1SS220NECQ24Transistor for switch2SK2158NECC3168 µ F Output capacitor20SA68M SANYO OS-CON, SA series D31Schottkey diode D1FS4SHINDENGENL3147 µ H Choke inductor636FY-470M TOKO D73F seriesQ31Switching transistor2SB1572NECQ32Buffer transistor2SA812NECQ33Buffer transistor2SC1623NECQ34Transistor for switch2SA812NECQ35Transistor for switch2SC1623NECQ36Transistor for switch2SC1624NECRemarks1.The capacitors that are not specified in the above list are multilayer ceramic capacitors.2.The resistors that are not specified in the above list are 1/4W resistors.22Data Sheet G13418EJ3V0DS00Data Sheet G13418EJ3V0DS00235.PACKAGE DRAWINGITEM B C J 16-PIN PLASTIC TSSOP (5.72 mm (225))D G H I P MILLIMETERS 0.65 (T.P.)0.375 MAX.1.0±0.20.240.924.4±0.16.4±0.2+0.06−0.043°+5°−3°NOTEEach lead centerline is located within 0.10 mm ofits true position (T.P.) at maximum material condition.E 0.09+0.06−0.04F 1.01+0.09−0.06A A' 5.0±0.15.15±0.15K L M N 0.50.1450.100.10+0.055−0.045R S0.250.6±0.15S16GR-65-PJG-16.RECOMMENDED SOLDERING CONDITIONSRecommended solder conditions for this product are described below.For details on recommended soldering conditions, refer to Information Document “Semiconductor Device Mounting Technology Manual” (C10535E).For soldering methods and conditions other than those recommended, consult NEC.Surface Mount Typeµ PC1935GR: 16-pin plastic TSSOP (5.72 mm (225))Soldering Method Soldering Conditions Symbol of RecommendedConditionsIR35-00-3Infrared reflow Package peak temperature: 235 °C, Time: 30 seconds MAX.
