2002 mar 11 6 philips semiconductors product speci?cation multiple voltage regulator with power switches tda3682 table 1 enable control pin en1 table 2 enable control pin en2 table 3 enable control pin en3 protections all output pins are fully protected against load dump and short-circuit (foldback current protection); see fig.3. at load dump all regulator outputs will go low, except the output of regulator 2 (bu5v). the power switches can withstand loss of ground. this means that the ground pin is disconnected and the switch output is connected to ground. backup function a backup function is present. this is realized by a switch function which acts like a sort of ideal diode between pins v p2 and stcp. the forward voltage of this ideal diode depends on the current flowing through this diode. this function makes it possible to supply regulator 2 (bu5v) when no supply voltage is present on pin v p2 . a special application can be made using a backup function by connecting a capacitor between pin stcp and ground. when the supply voltage is present on pin v p2 this capacitor will be charged to a level of v p2 - 0.3 v. this charge can now be used to supply regulator 2 for a short period of time when v p2 is switched to 0 v. the delay time can be calculated using the formula: example: v p2 = 14.4 v, v reg2 = 5 v, r l =1k w and c backup = 100 m f results in a delay time of 177 ms. when an overvoltage condition occurs, the voltage on pin stcp will be limited to approximately 18 v. en1 regulator output reg1 l off hon en2 regulator outputs reg3 reg4 reg5 l off off off m on off on h on on off en3 power switches sw1 sw2 l off off m off on honon mgt170 v o(reg) i sc i o(reg) i m fig.3 foldback current protection. t delay c backup r l v p2 v reg2 C 0.5 C v reg2 ----------------------------------------------- =

2002 mar 11 13 philips semiconductors product speci?cation multiple voltage regulator with power switches tda3682 application information n oise the outputs of regulators 1 to 5 are designed in such a way that the noise is very low and the stability is very good. the noise output voltage depends on output capacitor c o . table 4 shows the influence of the output capacitor on the noise figure. table 4 noise ?gures note 1. measured at a bandwidth from 20 hz to 20 khz. s tability the regulators are made stable with the externally connected output capacitors. the stability can be guaranteed with almost any output capacitor. when only an electrolytic capacitor is used, the temperature behaviour of this output capacitor can cause oscillations at extreme low temperature. the following two examples show how an output capacitor value is selected. oscillation problems can be avoided by adding a 47 nf capacitor in parallel with the electrolytic capacitor. example 1 (regulator 2) regulator 2 (bu5v) is stabilized with an electrolytic output capacitor of 10 m f (esr = 4 w ). at t amb = - 30 c the capacitor value is decreased to 3 m f and the esr is increased to 28 w . as can be seen from fig.8 the regulator will be instable at t amb = - 30 c. solution: to avoid problems with stability at low temperatures, the use of tantalum capacitors is recommended. use a tantalum capacitor with a value of 10 m f or an electrolytic capacitor with a higher value. example 2 (regulator 1) regulator 1 (illumination) is stabilized with an electrolytic capacitor of 2.2 m f (esr = 8 w ). at t amb = - 30 c the capacitor value is decreased to 0.8 m f and the esr is increased to 56 w . as can be seen from fig.9 the regulator will be stable at t amb = - 30 c. even when only a small mkt capacitor of 47 nf is used as the output capacitor, regulator 1 will remain stable over the temperature range. regulator noise figure ( m v) (1) c o =10 m fc o =47 m fc o = 100 m f 1 170 130 120 2 110 100 95 3 140 110 100 4 140 110 100 5 140 110 100 handbook, halfpage mgt176 c o ( m f) esr ( w ) maximum minimum stable region 100 10 0 4 8 12 1 0.1 fig.8 curve for selecting the value of the output capacitor for regulator 2. handbook, halfpage mgt177 c o ( m f) esr ( w ) maximum stable region 10 1 0 100 0.1 0.047 100 fig.9 curve for selecting the value of the output capacitor for regulators 1, 3, 4 and 5.

2002 mar 11 15 philips semiconductors product speci?cation multiple voltage regulator with power switches tda3682 soldering introduction to soldering through-hole mount packages this text gives a brief insight to wave, dip and manual soldering. a more in-depth account of soldering ics can be found in our data handbook ic26; integrated circuit packages (document order number 9398 652 90011). wave soldering is the preferred method for mounting of through-hole mount ic packages on a printed-circuit board. soldering by dipping or by solder wave the maximum permissible temperature of the solder is 260 c; solder at this temperature must not be in contact with the joints for more than 5 seconds. the total contact time of successive solder waves must not exceed 5 seconds. the device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (t stg(max) ). if the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. manual soldering apply the soldering iron (24 v or less) to the lead(s) of the package, either below the seating plane or not more than 2 mm above it. if the temperature of the soldering iron bit is less than 300 c it may remain in contact for up to 10 seconds. if the bit temperature is between 300 and 400 c, contact may be up to 5 seconds. suitability of through-hole mount ic packages for dipping and wave soldering methods note 1. for sdip packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board. package soldering method dipping wave dbs, dip, hdip, sdip, sil suitable suitable (1)
