SCALE Driver 2SD106AI Data Sheet 2SD106AI Dual SCALE Driver Core for IGBTs and Power MOSFETs Description The SCALE drivers from CONCEPT are based on a chip set that was developed specifically for the reliable driving and safe operation of IGBTs and power MOSFETs. The name “SCALE” is an acronym for the most outstanding properties of the SCALE series of drivers: SCALE = Scaleable, Compact, All purpose, Low cost and Easy to use. The SCALE driver is a winning project of the competition organized by “Technology Center Switzerland 1998”. And ABB Switzerland AG honored the development of the SCALE driver by distinguishing it as the “best power electronics project in 1998”.

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 these DC/DC converters are not protected against overload. This should be considered as a recommended value. Please consult the section: “Output power and self-heating”. Under-voltage monitoring for protecting the power semiconductors. The voltage refers to the local supply voltage of each individual drive channel. 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 LDI 00I can occur. Particular care must be taken when driving via cables or longer leads. The gate current must be limited to its maximum value by a gate resistor. At a load of 39nF in series with 5.6 : (typical load of a 1200V/100A IGBT). Maximum continuous or repeatedly-applied DC voltage between all inputs and all outputs. However, types that have been measured and selected for higher partial-discharge voltages (e.g. for 1700V IGBT modules) are also available. 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 - specially at high load - must be taken into account. The test voltage of 4000 Vac(rms)/50Hz may be applied only once during a minute. It should be noted that with this (strictly speaking obsolete) test method, some (minor) damage occurs to the isolation layers due to the partial discharge. Consequently, this test is not performed at CONCEPT as a series test. In the case of repeated isolation 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. IGBT-Driver.com Page 7 SCALE Driver 2SD106AI 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 is 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. Overview and application The SCALE driver 2SD106AI is a two channel-driver for power MOSFETs and IGBTs. Its compact mechanical dimensions and simple electrical interface make this driver suitable for almost all conceivable applications. When used as a half-bridge driver, the 2SD106AI can directly generate any dead times that may be required. Output power and self-heating The specified output power of the driver totals 2W (1W per channel). This typically suffices to drive a 100A/1200V six-pack IGBT module with 25kHz. In the case of a drive power of 2W, the typical input power of the driver is about 2.33W; the losses due to the driver total about 0.33W. 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 made. It is consequently recommended to check the self-heating of the system, especially when it is used at higher temperatures. For the calculation of 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.

SCALE Driver Module To correspond more effectively to the Fig. 4 Collector-sense circuit principle 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.

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 15µs.
