Six-pack SCALE Driver 6SD106E

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, C ompact, A ll purpose, L ow cost and E asy to use.

Footnotes to the key data

1) The drivers have a zener diode on each channel for over-voltage protection. When the feed voltage

exceeds 16V, this protection can be subject to thermal overload.

2) 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.

3) This should be considered as a recommended value. Please consult the section: “Output power and

self-heating”.

4) 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.

5) 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.

6) The gate current must be limited to its maximum value by a gate resistor.

7) At a load of 39nF in series with 5.6 W (typical load of a 1200V/100A IGBT).

8) 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 (e.g. for 1700V IGBT modules) are also available (see Note 11).

9) This specification guarantees that the drive information will be transferred reliably even at a high DC-

link voltage and fastest switching operations.

10) The application-specific self-heating of the drivers - specially at high load - must be taken into account.

11) 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).

12) 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.

13) The first series (1988) has a creep path of 7.0mm between adjacent channels. A creep path of 12.7mm

will be implemented (with 100% mechanical compatibility) in later series.

14) The typical blocking time after an error is 1 second. If required, versions with other blocking times

may also be supplied.

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 6SD106E is a six-pack driver for power MOSFETs and IGBTs.

The terminal pins of the 6SD106E driver are arranged so that the layout can be kept

very simple and the logic signal flow (input signal ⇒ drive circuit ⇒ power transistors) is

maintained. A distance of 12.7mm is observed between the drive signal and the power

potential!

Collector sense and dimensioning of Rth

The 6SD106E six-

path driver has a

collector-sense circuit

to protect the power

semiconductors. It is

shown in Fig. 4

Its basic operating

mode can be ob-

tained from the

brochure entitled:

“Description and

Application Manual

for Scale Drivers”.

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.

Notes on Table 1

The values for “Vth1” and “Vth2” are

listed in Table 1 as a function of the

reference resistance Rth.

The value in the “Vth1” column cor-

responds to the voltage threshold after

the response time has elapsed.

The value in the “Vth2” column cor-

responds to the voltage which is set up

statically across the resistor Rth. This

static value is typically reached after

between 10 and 15 µs.

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.

Output power and self-heating

The specified output power of the driver totals 6W (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 6W, the typical input power of the driver is about 7W; the losses due

to the driver total about 1 W. 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” from CONCEPT.
