Page 4: System Overview
The SCALE-2 driver chipset is a further development of the proven SCALE technology /2/. The basic topology of the 6SP0235T driver is shown in Fig. 2. The values for the gate resistors and other key components can be found in the specific datasheets for a given IGBT module /3/. -
Page 5: The Six Steps To Success
The following steps point out the easy way to use 6SP0235T drivers in power converters: 1. Choose a suitable driver When applying 6SP0235T drivers, you should note that they are specifically adapted to a particular type of IGBT module. The type designation of the driver consequently also includes a number corresponding to a specific IGBT module (see “Ordering Information”). -

Page 10: Description Of Interface X1
Description and Application Manual Description of Interface X1 General The interface X1 of the driver 6SP0235T is very simple and easy to use. The driver has the following terminals: 3 x power-supply terminals (but only one 15V power supply is needed) -
Page 11: Ina_X, Inb_X (Channel Drive Inputs, E.g. Pwm)
6SP0235T Target Half-bridge mode If the MOD input is low level (connected to GND), half-bridge mode is selected. In this mode, the inputs INA_x and INB_x have the following functions: INA_x is the drive signal input while INB_x acts as the enable input of the corresponding phase (see Fig. -
Page 12: Tb (Input For Adjusting The Blocking Time)
6SP0235T Description and Application Manual How the status information is processed A fault on the secondary side (detection of short-circuit of IGBT module or supply undervoltage) is transmitted to the corresponding SOx_x output immediately. The corresponding SOx_x output is automatically reset (returning to the high impedance state) after the blocking time Tb has elapsed (read the relevant data sheet for timing information /3/). -
Page 13: How Do 6Sp0235T Scale-2 Drivers Work In Detail
Vce monitoring for short-circuit protection, operation inhibit after fault, supply-undervoltage shutdown and status feedback. Outstanding features of 6SP0235T SCALE-2 drivers are: compact size, simple mounting - directly onto the IGBT module, advanced active-clamping function and short-pulse suppression. Active clamping describes an active scheme designed to protect the IGBTs against overvoltage during turn-off. -
Page 14: Power Supply And Electrical Isolation
6SP0235T Description and Application Manual Power supply and electrical isolation The driver is equipped with a DC/DC converter to provide an electrically insulated power supply to the gate driver circuitry. The signal isolation is realized with transformers. All transformers (DC/DC and signal transformers) feature safe isolation to EN 50178 and IEC 60664-1, protection class II between primary side and either secondary side (refer to the data sheets /3/). -
Page 15: Ce Monitoring / Short-Circuit Protection
6SP0235T Target monitoring / short-circuit protection The basic V monitoring circuit implemented in Driver 6SP0235T SCALE-2 drivers is illustrated in Fig. 9. Input The IGBT collector-emitter voltages are measured Voltage with a resistor network. V is checked after the response time (see Fig. 10) at turn-on to detect a short circuit. -
Page 16: Turn-Off Of The Igbt
Basic active-clamping topologies implement a single feedback path from the IGBT’s collector through transient voltage suppressor devices (TVS) to the IGBT gate. The 6SP0235T SCALE-2 drivers support CONCEPT’s advanced active clamping based on this principle: when active clamping is activated, the turn-off MOSFET of the driver is switched off in order to improve the effectiveness of the active clamping and to reduce the losses in the TVS. - Page 17 For the maximum permitted DC-link voltage, refer to the gate driver data sheets /3/. Figure 12 shows an exemplary turn-off transition of an 800A/650V IGBT module controlled with a 6SP0235T driver.

Low-inductance layout The active-clamping function should not lead anyone to forget about the inductances of the power stack. For several reasons, it is still necessary to reduce the DC-link stray inductance to about 25nH with 6SP0235T plug- and-play drivers.
