IHD260/660 Preliminary Data Sheet IHD 260/660 Dual Channel SCALE IGBT Driver Core A successor to the IHD 215/280/680 dual-gate driver cores for 1200V and 1700V IGBTs The IHD 260 and IHD 660 (short IHDx60) are highly-integrated dual IGBT driver cores based on CONCEPT's proprietary SCALE technology which has been established on the market as an industrial standard since 1999. As most customers apply the IHD 215, IHD 280 and IHD 680 drivers in a similar way, the IHDx60 covers a dedicated set of compatible items to give the benefits of optimum performance, optimum reliability and a competitive price. The driver cores are optimized to match various IGBTs and applications from 25A to 450A and 1200V to 1700V. Typical applications include half-bridge control of 1700V/75A IGBTs at switching frequencies up to 100kHz and 1700V/450A IGBTs at switching frequencies up to 18.5kHz for the IHD660 version.

In this data sheet, the text referring to critical compatible items is underlined. Option N and Option I select between non-inverting and inverting inputs respectively. It is no longer possible to interchange the IN+ and IN- inputs to invert the logic as could be done with IHD 215/280/680. On the secondary side, any fault state is extended by a period known as the command blocking time. During this time, the driver is kept in the off-state. The command blocking time is set at the factory to a nominal value of 25ms. Other values upon request. It is no longer possible for the application to adjust the blocking time. For option T, the signal transformer interface is used to transfer the secondary fault signal to the primary side. This transfer may be performed at each change in the command signal, but only during the blocking time. For option C, an optocoupler is used to transfer the secondary-side fault state to the primary side within a delay of less than several microseconds. The initial creepage distance and the maximum operating voltage are reduced by the optocoupler. For a summary, refer to the Ordering Information section on the last page.

To provide a bipolar gate-driving voltage with the nominal values of V(G, E) = +15.1V for turn-on and V(G, E) = - 15.1V for turn-off, both gate and emitter are switched in full-bridge configuration via biploar junction transistors (providing a total nominal level shift of 1.3V). The primary side is equipped with an automatic power-on reset which clears the fault memories when the supply voltage approaches a specified limit with a maximum value of 13.5V. In typical applications (hard-switching topology using recommended gate resistors and gate charge) the switching frequency is primarily limited by the switching losses of the IGBT module or by the gate power due to the gate charge required by the module. The switching losses of the gate driver depend strongly on the particular operating conditions and increase with reducing the gate resistance and increasing switching frequency. For switching frequencies beyond 10kHz or gate charges beyond 55μC, the thermal limits of the gate driver may be exceeded. A derating of the IGBT average gate power is required under these estimated exemplary conditions. Conditions other than those specified may affect the reliability or lead to thermal breakdown of the gate drivers. Please ask our support team for a specific estimation. As a rule, the case temperature of any component of the gate driver should stay below 65°C for an ambient temperature of 25°C. The total external gate resistance is the sum of the IGBT-internal chip resistances and the externally used gate resistors. Note that the driver-internal minimum resistance is below 0.2Ω. Due to the finite slew rate of the driver output voltage and to parasitic inductances in the gate control loop, however, the resulting gate current may not approach the nominal maximum value of 6.0A. Equivalent delay, rise or fall times are derived from comparisons with the results obtained when modeling the driver as an ideal pulse-shaped voltage source with no delay and an infinite slew rate. At the REF pin, a 1.5 kΩ resistor is connected to the positive voltage terminal Cs of the secondaryside power supply in parallel with a nominal 150μA current source. The reference voltage may be set via an external Zener diode or an external resistor connected to pin E. Furthermore, at pin ME a 2.2 kΩ resistor is connected to Cs in parallel with a nominal 1.4mA current source. This solution should be fully compatible with IHD series gate drivers in terms of function and parameters. Maximum continuous or repeatedly applied DC voltage or peak value of the repeatedly applied AC voltage between any primary-side pin and any secondary-side pin. Caution for option C: operating voltages exceeding 600V may degrade the long-term characteristics of the optocouplers, resulting in an increased delay or a reduced current capability at pins SO*. The test voltage of 4000 Vac(rms)/50 Hz 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. Where repeated insulation tests (e.g. module test, equipment test, system test) are run, the subsequent tests should be performed at a lower test voltage: the test voltage is reduced by 400 V for each additional test. The more modern if more elaborate partialdischarge measurement is preferable to such test methods as it is almost entirely non-destructive. The partial discharge test is performed for each driver within the scope of series production. The supported gate charge refers to the stability of the power supply voltages and to a dynamic voltage drop of 0.3V. Exceeding the maximum supported gate charge may lead to malfunction or thermal overload of the gate drivers. The customer may increase the specified maximum value of the supported gate charge by connecting additional supply capacitors between terminals Cs and COM up to a total of 47μF. Absolute gate charge must not exceed 55μC.
