Footnotes to the Key Data

1)

The maximum peak gate current refers to the highest current level occurring during the product

lifetime. It is an absolute value and does also apply for short pulses.

2)

The average supply input current is limited for thermal reasons. Higher values than specified by the

absolute maximum rating are permissible (e.g. during power supply start up) if the average remains

below the given value, provided the average is taken over a time period which is shorter than the

thermal time constants of the driver in the application.

3)

There is no means of actively controlling or limiting the input current in the driver. In the case of

start-up with very high blocking capacitor values, or in case of short circuit at the output, the supply

input current has to be limited externally.

4)

The maximum output power must not be exceeded at any time during operation. The absolute

maximum rating must also be observed for time periods shorter than the thermal time constants of

the driver in the application.

5)

An extended output power range is specified in the output power section for ambient temperatures

limited from 0°C to 70°C.

6)

The delay time is measured between 50% of the input signal and 10% voltage swing of the

corresponding output. The delay time is independent on the output loading.

7)

Output rise and fall times are measured between 10% and 90% of the nominal output swing with an

output load of 4.7Ω and 270nF. The values are given for the driver side of the gate resistors. The time

constant of the output load in conjunction with the present gate resistors leads to an additional delay

at the load side of the gate resistors.

8)

External blocking capacitors should be placed between the VISOx and VEx as well as the VEx and

COMx terminals. Refer to “2SC0635T Description & Application Manual” (paragraph “DC/DC output

(VISOx), emitter (VEx) and COMx terminals)” for recommendations. Ceramic capacitors are

recommended.

9)

The minimum response time is valid for the circuit given in the description and application manual

(Fig. 7) with the values of table 1.

10)

The blocking time sets a minimum time span between the end of any secondary-side fault state and

the start of normal operation (remove fault from pin SOx). The value of the blocking time can be

adjusted at pin TB.

11)

Undervoltage monitoring of the primary-side supply voltage (VCC to GND). If the voltage drops below

this limit, a fault is transmitted to both SOx outputs and the power semiconductors are switched off.

12)

Undervoltage monitoring of the secondary-side supply voltage (VISOx to VEx and VEx to COMx, which

correspond to the approximate turn-on and turn-off gate-emitter voltages). If the corresponding

voltage drops below this limit, a fault is transmitted to the corresponding SOx output and the IGBT is

switched off after the corresponding delays. Refer to “2SC0635T Description & Application Manual” for

more details.

13)

Transmission delay of fault state from the secondary side to the corresponding primary-side status

output.

14)

HiPot testing (= dielectric testing) must generally be restricted to suitable components. This gate

driver is suited for HiPot testing. Nevertheless, it is strongly recommended to limit the testing time to

1s slots. Excessive HiPot testing at voltages much higher than 3182VAC(eff) may lead to insulation

degradation. No degradation has been observed over 1min. testing at 10.2kVAC(eff). Every production

sample shipped to customers has undergone 100% testing at the given value for 1s.
