When the feed voltage exceeds 16V, this protection can be subject to thermal overload. If the specified power consumption is exceeded, this indicates an overload of the DC/DC converter. It should be noted that the DC/DC converter is not protected against overload. This should be considered as a recommended value. Please consult the section: "Output power and self-heating". Especially when the drivers produce continuously short pulses (on-time or offtime < 1.5s), their self-heating can be considerably increased. The maximum power of the drivers should be reduced in this case. Under-voltage monitoring for protecting the power semiconductors. The voltage refers to the local supply voltage VPOS. However, this corresponds approximately to the voltage at VDC with respect to GND. The input levels must never exceed the limits of the supply voltage (i.e. between GND and VDD), otherwise latch-up of the integrated circuits LDI001 can occur. Particular care must be taken when driving via cables or longer leads. See also application note AN-9901 on www.IGBT-Driver.com. The gate current must be limited to its maximum value by a gate resistor. First value: At a load of 94nF in series with 1.95. Second value: At a load of 660nF in series with 0.6 Maximum continuous or repeatedly applied DC voltage or peak value of the repeatedly applied AC voltage between all inputs and all outputs. However, types that have been measured and selected for higher partial-discharge voltages are also available (see note 11). This specification guarantees that the drive information will be transferred reliably even at a high DC-link voltage and fastest switching operations. The application-specific self-heating of the drivers - especially at high load - must be taken into account. The partial discharge is not measured for the standard types. Tested and selected types with guaranteed partial-discharge immunity can be supplied for applications with maximum requirements and higher operating voltages (such as railroad applications). The test voltage of 4000 Vac(rms)/50Hz may be applied only once during one minute. It should be noted that with this (strictly speaking obsolete) test method, some (minor) damage occurs to the insulation layers due to the partial discharge. Consequently, this test is not performed at CONCEPT as a series test. In the case of repeated insulation tests (e.g. module test, equipment test, system test), the subsequent tests should be performed with a lower test voltage: the test voltage is reduced by 400V for each additional test. The more modern if more elaborate partial-discharge measurement is better suited than such test methods as it is almost entirely non-destructive. The typical blocking time after an error is 1 second. If required, versions with other blocking times may also be supplied. Page 8 INTELLIGENT POWER ELECTRONICS 1SD1548AI UL Data Sheet Application Hints IMPORTANT INFORMATION This data sheet contains only product-specific data. All data that apply to the whole type series of SCALE drivers are given in the document entitled: "Description and Application Manual for SCALE Drivers". In particular, this manual contains a detailed description of the concept of the SCALE drivers, a description of the function of all terminal pins as well as other important application hints. Note: As the 1SD1548AI UL is a single-channel driver, the LDI always operates in direct mode. Overview and application The SCALE driver 1SD1548AI UL is a single-channel driver for IGBTs. The 1SD1548AI UL combines compact mechanical dimensions and a simple electrical interface with very high output currents, very high drive power and a special high insulation. This driver can thus be used in almost all conceivable applications, especially for parallel-driving high-power IGBT modules with reverse voltages up to 1700V. Output power and self-heating The specified output power of the driver totals 15W. This typically suffices to drive a 1200A/1200V IGBT module with 40kHz. In the case of a drive power of 15W, the typical input power of the driver is about 18W; the losses due to the driver total about 3W. Because CONCEPT cannot predict how the drivers will be incorporated in the user's application, no binding recommended value for self-heating and thus for the maximum useful output power at high ambient temperatures can be given. It is consequently recommended to check the self-heating of the system, especially when it is used at higher temperatures and if the driver is used with short pulses (on-time or off-time< 1.5 s) continuously. For calculating the exact output power, reference should be made to Application Note AN-9701 "IGBT drivers correctly calculated" on www.igbt-driver.com/go/app-note. IGBT-Driver.com Page 9 1SD1548AI UL Data Sheet Collector sense and dimensioning of Rth The 1SD1548AI UL driver has a collector-sense circuit to protect the power semiconductors. It is shown in Fig. 4. Its basic operating mode can be obtained from the brochure entitled: "Description and Application Manual for Scale Drivers". To correspond more effectively to the turn-on characteristic of the IGBTs, the SCALE drivers do not use a static reference voltage to compare the voltage at the collector. Instead, the reference is used as shown in Fig. 5. +VPOS 1,4mA +VPOS 150uA OVERCURRENT Rm 180R Dm (2 x 1N4007) C Ca Rth RG MEASURING G Rth E SCALE Driver 1SD1548AI External Circuit Fig. 4 Collector-sense circuit principle In order to ensure that the 1SD1548AI UL can be applied as universally as possible, the components Ca (response time capacitor) and Rm (attenuation resistor) are not integrated in the driver as shown in Fig. 4, but must be connected externally. Whereas Ca can be matched to the specific application, a standard value of 180 is recommended for Rm. The ground terminal of Ca should be connected to the COM pin. Page 10 INTELLIGENT POWER ELECTRONICS 1SD1548AI UL Data Sheet Notes on Table 1 +Vdc The values for "Vth1" and "Vth2" are listed in Table 1 as a function of the reference resistance Rth. Vce Detail Vth 0V Response time Detail view Vth1 Vce Vth2 0V Fig. 5 Collector-sense voltage curve The value in the "Vth1" column corresponds to the voltage threshold after the response time has elapsed. The value in the "Vth2" column corresponds to the voltage which is set up statically across the resistor Rth. This static value is typically reached after between 10 and 15 s. The value in the VCE(off) column corresponds to the collector-emitter voltage value at which the protection function is activated when the external circuit is used as shown in Fig. 4 with one or two Dm diodes of type 1N4007 connected in series. A value of 1n5 is used for the response time capacitor Ca. If this capacitor is rated higher or lower, the response time changes in proportion to the change in capacitance, whereas the thresholds Vth1 and Vth2 remain practically unchanged (they are specified by Rth).

It is strictly recommended to connect these in parallel on the layout so that the voltage drop across the lead frames (contact pins) is minimized. Moreover, input pins 21 and 22 must also be connected to VDC. Special terminal pins The 1SD1548AI UL driver is optimized for universal use and high driver performance and thus contains more terminal pins than the compact SCALE drivers. These pins will be described below: VPOS, COM and VNEG pins: external support capacitor Like the compact SCALE drivers, the 1SD1548AI UL also has blocking capacitors on the secondary side of the DC/DC converter. IGBTs with gate charges up to 12C (corresponding typically to about a 1200V/1200A module) can be driven without external blocking capacitors. At higher gate charges, external blocking capacitors are required between VPOS - COM and COM - VNEG. These capacitors should be rated between 10 and 42F (but not more than 84 F) with a dielectric strength of 20V. It is important for the capacitors to be suitable for switched-mode power supply applications (low inductance and high current handling capability). They must be connected as closely as possible to the driver's terminal pins with minimum inductance. The anode of the capacitor is connected to VPOS (COM), its cathode to COM (VNEG). VDC and GND pins: supply for DC/DC converter It is recommended to connect a blocking capacitor of approximately 220F to the driver input. This capacitor should also be of the switched-mode power supply type. Pin LS: Local status The status of the IGD 001 is available at this output. It is an open-collector output to which approximately 5mA may be applied. A LED can be connected here, for example, as shown in Fig. 6. The LED lights up in normal operation (everything OK) and goes out when the driver detects an undervoltage or during the blocking time. Page 12 INTELLIGENT POWER ELECTRONICS 1SD1548AI UL Data Sheet Insulated +16V VPOS SCALE Driver 3k3 LED OK LS Ds COM Fig. 6 Status display with LED at pin LS Caution: The Schottky diode Ds should not be omitted if the local status output is used. If the local status output is not used, LS should be connected to COM in order to increase the noise immunity of the driver. Pin AC: Enhanced active clamping Pin AC allows the basic active clamping function of the driver to be improved (see Fig. 1). If it is not used, it should be connected to VNEG. As the appropriate dimensioning of improved active clamping is complex, timeconsuming and not necessary for most applications, CONCEPT does not support this feature. However, if this function should be required, or for more information, please contact CONCEPT's technical support. Configuration within the power section The drivers should be located as closely as possible to the power transistors. The connecting leads to the transistors should be as short as possible and as low inductance as possible, i.e. they can be up to 3 cm to 10 cm long depending on the gate current and switching speed.
