2SC0435T2E0-17 Preliminary Datasheet
Dual-Channel Low-Cost SCALE™-2 IGBT and MOSFET Driver Core
Abstract
The low-cost SCALE™-2 dual-driver core 2SC0435T2E0-17 (Lead free version of 2SC0435T2C0-17) combines
unrivalled compa ctness with broa d appli cabilit y. T he dr iver is designed for univer sal a pplications requiri ng high
reliability. The 2SC0435T2E0-17 drives all usual high-power IGBT modules up to 1700V. The embedded
paralleling capability allows easy inverter design cover ing higher power ratings. Multi-level topologie s are also
supported.
The 2SC0435T2E0-17 is the most compact driver core in its power range with a footprint of only 57.2 x
51.6mm and an insertion height of max. 20mm. It allows even the most restricted insertion spaces to be
efficie ntly used. Compar ed wi th conve ntional dri vers, t he highly i ntegrat ed SCALE -2 chipset allows a bout 85%
of components to be dispensed with. This advantage is impressively reflected in increased reliability at
simultaneously minimized cost.
The 2SC0435T2E0-17 combines a complete two-channel driver core with all components required for driving,
such as an isolated DC/DC converter, short-circuit protection, advanced active clamping as well as supply
voltage monitoring. Each of the two output channels is electrically isolated from the primary side and the other
secondary channel.
An output current of 35A a nd 4W drive power is available per channel, making the 2SC0435T2E0-17 an ideal
driver platform for u niversal usage in me dium and high-power applications. The driver provides a gate voltage
swing o f +1 5V /-1 0V . The t urn-on voltage is re gulate d to mainta in a stable 15V r e gardle ss of the outp ut po we r
level.
Its outstanding EMC allows safe and reliable operation in even hard industria l applications.

Output voltage swing
The output voltage swing consists of two distinct se gments. First, there is the tu rn-on voltag e VGHx between
pins GHx and VEx. VGHx is regulated and maintained at a constant level for all output power values and
frequencies.
The seco nd segm ent o f the output voltag e swing i s the turn-off vo ltag e VGLx. VGLx is measured between pins
GLx and VEx. It is a negative voltage. It changes with the output power to accommodate the inevitable
voltage drop across the internal DC/DC converter.

Footnot es to the K ey D a ta
1) The maximum peak gate current refers to the highest current level occurring during the product
lifetime. It is an absolute value and does a lso apply for short pu lses.
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 limi ted externall y.
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.

Prelim i nary Dat a Shee t

5) An extended output power range is specified in the output power section for maximum ambient
temperatures of 70°C. In that case, the absolute maximum rating for the operating temperature
changes to (–40°C - 70°C) and the absolute m aximum output power rating changes to 6W.
6) The delay time is measured between 50% of the input signal and 10% voltage swing of the
corresp o nding out put. The delay time is independent of the output lo ading.
7) Output rise and fall ti mes are meas ured betwee n 10% and 90% of the nomi nal output swing w ith 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 wit h the present ga te resistors lea ds to an additio nal delay
at the load side of the gate resistors.
8) External blocking capacitors are to be placed between VISOx and VEx as well as VEx and COMx for
gate charges exceeding 3µC. Ceramic capacitors are recommended. A minimum external blocking
capacitance of 3µF is recommended for every 1µC of gate charge beyond 3µC. Insufficient external
blocking can lead to reduced driver efficiency and thus to therm al over load.
9) The minimum response time given is valid for the circuit given in the description and application
manual (Fig. 7) with the values of table 1 (Cax=0pF, Rthx=43kΩ).
10) The blocking time sets a minimum time span between the end of any 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. The specified blocking time is valid if TB is connected to GND.
11) This spe cification guara ntees that the drive in formation will be tra nsferred reliabl y even at a high DC-
link voltage and with ultra-fast switching operations.
12) Undervoltage monitoring of the primary-side supply voltage (VCC to GND). If the voltage drops below
this limit, a fault is transmitted t o both SOx outputs and the power semiconductors ar e switched off.
13) Unde rvolta ge monitor ing of the seco ndary-side suppl y voltage (VI SOx to VEx and VEx to COMx w hich
correspond with the approximate turn-on and turn-off gate-emitter voltages). If the corresponding
voltage drops below this limit, t he IGBT is switched off and a fault is transmitted t o the corresponding
SOx output.
14) Transmission delay of fault state from the secondary side to the corresp onding primar y status output.
15) HiPot testing (= dielectric testing) must generally be restricted to suitable components. This gate
driver is suited for HiPot te sting. Nevertheless, it is st rongly recommended to limi t the testing time to
1s slots as stipulated by EN 50178. Excessive HiPot testing at voltages much higher than 1200V AC(eff)
may lead to insulation degradation. No degradation has been observed over 1min. testing at
5000VAC(eff). Ever y production sample s hipped to customers has u ndergone 100% t esting at the given
value for 1s.
16) Partial discharge measurement is performed in accordance with IEC 60270 and isolation coordination
specified in E N 50178. The par tial discharge extincti on voltage bet ween primary and e ither secondary
side is coordinated for safe isolat ion to EN 50178.
17) Jitter measurements are performed with input signals INx switching between 0V and 5V referred to
GND, with a corresponding rise time and fall time of 15ns.
