Footnotes to the Key Data
The transceivers required on the host controller side are not supplied with the gate driver. It is
recommended to use the same types as used in the gate driver. For product information
,
refer to
www.power.com/igbt-driver/go/fiberoptics.
The recommended transmitter current at the host controller is 20mA. A higher current may increase
jitter or delay at turn-off.
The typical transmitter current at the gate driver is 20.5mA. In case of supply undervoltage, the
minimum transmitter current at the gate driver is
15mA: this is suitable for adequate plastic optical
fibers with a length of up to 10 meters.
The maximum peak gate current refers to the highest current level occurring during the product
lifetime. It is an absolute value and also applies to short pulses.
Twice the given minimum resistance value must be inserted between the interface connectors GH and
GL.
Moreover, the given minimal resistance value must be used in the full gate turn-on (interface
connector GH to gate) and turn-off (interface connector GL to gate) path.
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 th
is average is taken over a time period which is shorter than the
thermal time constants of the driver in the application.
There is no protection against light overload of the power supply. In the case of start-up with very
high blocking capacitor values, or of short circuit
/heavy overload
at the output, the supply input
current is limited
internally. The time during which the driver output is shorted/overloaded must be
limited externally and must be within the absolute maximum rating.
The maximum output power must not be exceeded at any time during operation. It must also be
observed for time periods shorter than the thermal time constants of the driver in the application.
An extended output power range is specified in the output power section for ambient temperatures
limited from -40°C to 70°C.
The gate-boosting output power can be calculated according to “1SC0450V Description & Application
Manual” and
is specified as a part of the gate driver’s total output power, which is
-on power over the output GH plus the gate-boosting power over the output VGB. The turn-on
equals the turn-off power of the output GL. The gate boosting is not active at
Including the delay of the external fiber-optic links (cable length: 1m). Measured from the transition of
the turn
-on or turn-
off command at the optical transmitter on the host controller side to the direct
output of the gate drive unit (excluding the dela
y of the gate resistors). The delay time is measured
between 50% of the input signal and
the 10% voltage swing of the corresponding output. The delay
time is independent of the output loading.
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
se 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.
External blocking capacitors should be placed between the VISO and VE as well as the VE and COM
terminals. Refer to “1SC0450V Description & Application Manual” (paragraph “DC/DC output (VISO),
emitter (VE) and COM terminals)” for recommendations. Ceramic capacitors are recommended.
The minimum response time is valid for the circuit given in the description and application manual
with the values of the corresponding tables.
Measured on the host side. The fault status on the secondary side is extended by the “delay in IGBT
turn
-off” and automatically reset after the specified time.
Refer to “1SC0450V Description &
Application Manual” for more details.
Undervoltage monitoring of the primary-side supply voltage (VCC to GND). If the voltage drops below
this limit, a fault is transmitted to the SO output.
Undervoltage monitoring of the secondary-side supply voltage (VISO to VE and VE to COM, 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
fiber-optic output and the IGBT is switched
off after the corresponding delay. Refer to “1SC0450V Description & Application Manual” for more
