max4506/max4507 fault-protected, high-voltage signal-line protectors 8 _______________________________________________________________________________________ two clamp circuits limit the output voltage to within the supply voltages. when the power supplies are off, any input voltage applied at in turns off both n1 and p1, and out is clamped to 0v. normal operation when power is applied, each protector acts as a resis- tor in series with the signal path. any voltage source on the ?nput?side of the switch will be conducted through the protector to the output (figure 2). when the output load is resistive, it draws current through the protector. the internal resistance is typically less than 100 ? . high-impedance loads are relatively unaffected by the presence of the max4506/max4507. the protector? path resistance is a function of the supply voltage and the signal voltage (see typical operating characteristics ). fault protection, power off when power is off (i.e., v+ = v- = 0), the protector is a virtual open circuit. with up to ?0v applied to the input pin, the output pin will be 0v. fault protection, power on a fault condition exists when the voltage on the in_ exceeds either supply rail. this definition is valid when power is on or off, as well as during all states while power ramps up or down. applications information supplying power through external ics the max4506/max4507 have low supply currents (<250?), which allows the supply pins to be driven by other active circuitry instead of connected directly to the power sources. in this configuration, the parts can be used as driven fault-protected switches with v+ or v- used as the control pins. for example, with the v- pin grounded, the output of a cmos gate can drive the v+ pin to turn the device on and off. this can effectively connect and disconnect three (max4506) or eight (max4507) separate signal lines at once. ensure that the driving source(s) does not drive the v+ pin more negative than the v- pin. figure 3 shows a simple turn-on delay that takes advantage of the max4506? low power consumption. the two rc networks cause gradual application of power to the max4506, which in turn applies the input signals smoothly after the amplifier has stabilized. the two diodes discharge the two capacitors rapidly when the power turns off. note that the ic used to supply power to the max4506/max4507 must be able to sup- ply enough current to maintain the load voltage at the supply rail in a fault condition. max4506 r out v in in1 v- v- v+ v+ 1 4 7 8 out1 figure 2. application circuit max4506 in3 v- -15v v+ +15v 3 4 5 10 f 10 f out3 in2 26 out2 in1 17 out1 8 100k ? 100k ? op amp figure 3. turn-on delay
max4506/max4507 fault-protected, high-voltage signal-line protectors _______________________________________________________________________________________ 9 protectors as circuit elements each of the protectors in a max4506/max4507 may be used as a switched resistor, independent of the func- tions of other elements in the same package. for exam- ple, figure 4 shows a max4506 with two of the protectors used to protect the input of an op amp, and the third element used to sequence a power supply. combining the circuits of figures 3 and 4 produces a delayed action on the switched +15v, as well as smooth application of signals to the amplifier input. figure 5 shows max4506 used in front of a max338 unprotected 1-to-8 multiplexer. with supplies at ?5v, v out of the max4506 clamps to ?5v; v out of the max338 goes to ?4v. with supplies off, v out goes to 0v while the inputs remain at ?5v. use the max4506 with a max338 to enhance voltage handling capability (figure 6). the max4506 and max338 share almost equal voltage drops in this con- figuration. for example, applying ?0v on pins 1 and 2 of the max4506 causes a voltage drop of about 26v across pin 1 of the max4506 to pin 4 of the max338, and a voltage drop of about 28v across pin 4 of the max4506 to pin 8 of the max338. similarly, there is a 26v drop from pin 2 of the max4506 to pin 5 of the max338. the system? performance exceeds each individual part? specification because of shared volt- age drops. multiplexer and demultiplexer as shown in figure 7, the max4506 can be used in series with the output of a max4508 (1-to-8 multiplexer) to act as multiplexer or demultiplexer. the max4508 is a fault-protected multiplexer whose inputs are designed to interface with harsh environments; however, its common output is not fault protected if connected to outside sig- nals (i.e., demultiplexer use). if the common output can see fault signals, then it needs to be protected, and the max4506 can be added to provide complete protection. switched +15v max4506 in3 v- -15v v+ +15v 3 4 5 out3 in2 26 out2 in1 17 out1 8 p 100k ? op amp 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 max338 -15v 1 2 8 7 +15v r l -25v +25v 3 4 6 5 max4506 a1 a2 gnd v+ no5 no6 no7 no9 a o en v- ov +5v +3v +15v -5v no3 no1 no2 no4 v out figure 4. power-supply sequencing 16 15 14 13 12 11 10 9 1 2 3 4 5 6 7 8 max4508 -15v 1 2 8 7 +15v new com 3 4 6 5 max4506 a1 a2 gnd v+ no5 no6 no7 no9 a o en v- o +5v +3v +15v -15v no3 no1 no2 no4 com figure 7. multiplexer and demultiplexer application using max4506 (or max4507) with max4508 v out = -14v +40v -40v 10k ? 6 4 7 1 5 2 8 max338 max4506 figure 6. spdt switch application figure 5. protecting a max338 with a max4506
max4506/max4507 as seen in figure 7, the signal input can now be put into pin 1 of the max4506 (new common output for sys- tem), and outputs can be taken at max4508 pins 4 to 7, and 9 to 12. this is the classic demultiplexer opera- tion. this system now has full protection on both of the multiplexers?inputs and outputs. measuring path resistance measuring path resistance requires special techniques, since path resistance varies dramatically with the in and out voltages relative to the supply voltages. conventional ohmmeters should not be used for the fol- lowing two reasons: 1) the applied voltage and currents are usually not predictable, and 2) the true resistance is a function of the applied voltage, which is dramatically altered by the ohmmeter itself. a utoranging ohmmeters are particularly unreliable. figure 8 shows a circuit that can give reliable results. this circuit uses a 100mv voltage source, a low-volt- age-drop ammeter as the measuring circuit, and an adjustable supply to sweep the analog voltage across its entire range. the ammeter must have a voltage drop of less than one millivolt (up to the maximum test cur- rent) for accurate results. a keithley model 617 elec- trometer has a suitable ammeter circuit, appropriate ranges, and a built-in voltage source designed for this type of measurement. find the path resistance by set- ting the analog voltage, measuring the current, and cal- culating the path resistance. repeat the procedure at each analog and supply voltage. note: it is important to use a voltage source of 100mv or less. as shown in figure 8, this voltage and the v in voltage form the v out voltage. using higher voltages could cause out to go into a fault condition prematurely. high-voltage surge suppression these devices are not high-voltage arresters, nor are they substitutes for surge suppressors. however, the max4506/ max4507 can fill a vital gap in systems that use these forms of protection (figure 9). although surge suppressors are extremely fast shunt elements, they have very soft current knees. their clamp voltage must be chosen well above the normal signal levels, because they have excessive leakage currents as the analog signal approaches the knee. this leakage current can interfere with normal operation when signal levels are low or impedance is high. if the clamp voltage is too high, the input can be damaged. connecting a max4506/max4507 after a surge sup- pressor allows the surge-suppressor voltage to be set above the supply voltage (but within the overvoltage limits), dramatically reducing leakage effects (figure 9). during a surge, the surge suppressor clamps the input voltage roughly to the ?0v supplies. fault-protected, high-voltage signal-line protectors 10 ______________________________________________________________________________________ max4506 v out v in in1 v- v+ v+ 100mv path resistance = 100mv/a adjustable analog voltage 8 4 out1 a max4506 in3 v- surge suppressors -15v -10v v+ +10v 3 4 5 out3 in2 26 out2 in1 17 out1 8 op amp figure 8. path-resistance measuring circuit figure 9. surge-suppression circuit
