FUNCTIONAL DESCRIPTION The TDA3617 is a multiple output voltage regulator with three independent switchable regulators. When the supply voltage is available (VP > 4.5 V), regulators 1, 2 and 3 can be operated by means of three independent enable inputs. Schmitt trigger functions are included to switch the regulators off at low battery voltage (VP < 4 V). A hysteresis is included to avoid random switching. All output pins are fully protected. The regulators are protected against load dump (the regulators switch off at VP > 20 V) and short circuit (foldback current protection).
TDA3617
The TDA3617 has a hold circuit which indicates when one of the regulators is out-of-regulation. The hold function is disabled when all the enable inputs are LOW (TDA3617 in standby mode). The HOLD output (open-collector output) can be wired OR-ed with other hold outputs of other regulator parts (e.g. TDA3618). When all the regulators of the TDA3617 are disabled (switched off), the HOLD output will be high ohmic. Because of this feature, the hold will not influence the hold information when wired OR-ed with other regulator parts. Figure 3 shows the total timing of a semi-on/off logic set. Figure 4 shows the total timing of the HOLD signal.

2. The quiescent current is measured in the standby mode. Therefore, the enable inputs of regulators 1, 2 and 3 are LOW (Ven < 1 V). 3. The drop-out voltage of regulators 1 and 2 is measured between VP and VREG1 or VREG2 respectively. 4. At current limit, IREGmn is held constant (see Fig.5 for the behaviour of IREGmn). 5. The foldback current protection limits the dissipated power at short circuit (see Fig.5). 6. Perform the load regulation test with sine wave load of 10 kHz on the regulator output under test. Measure the RMS ripple voltage on each of the remaining regulator outputs, using a 80 kHz low-pass filter.

Application information NOISE Table 1 Noise figures NOISE FIGURE (V)(1) REGULATOR 1 2 3 Note 1. Measured at a bandwidth of 200 kHz. The noise on the supply line depends on the value of the supply capacitor and is caused by a current noise (output noise of the regulators is translated to a current noise by means of the output capacitors). The noise is minimum when a high frequency capacitor of 220 nF in parallel with an electrolytic capacitor of 100 F is connected directly to pins 3 and 8 (supply and ground).

STABILITY The regulators are stabilized with the externally connected output capacitors. The value of the output capacitors can be selected by referring to the graph illustrated in Fig.7. When an electrolytic capacitor is used, its temperature behaviour can cause oscillations at Tamb < -20 C. In this case, use a tantalum capacitor. The two examples on the next page show how an output capacitor value is selected.

Example 1
Regulators 1, 2 and 3 are stabilized with an electrolytic output capacitor of 220 F (ESR = 0.15 ). At Tamb = -30 C the capacitor value is decreased to 73 F and the ESR is increased to 1.1 . The regulator will remain stable at Tamb = -30 C.

Example 2
Regulators 1, 2 and 3 are stabilized with an electrolytic output capacitor of 10 F (ESR = 3.18 ). At Tamb = -30 C the capacitor value is decreased to 3.3 F and the ESR is increased to 23 . The regulator will be instable at Tamb = -30 C.

Solution
Use a 47 nF HF capacitor in parallel with the output electrolytic output capacitor. As can be seen from the graph in Fig.7, the regulators will remain stable with an output capacitor of 47 nF onwards. The electrolytic output capacitor is only needed to minimize the output noise.

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.
TDA3617
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 (Tstg(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.
