Single-Channel High-Power and High-Frequency SCALE-2 Driver Core
Abstract
The 1SC2060P is a 20W, 60A SCALE-2 driver core. It is designed for high-power and high-frequency IGBT and
MOSFET applications such as induction heating, resonant and high-frequency power conversion as well as
parallel gate driving of large modules.
The 1SC2060P features newly developed planar transformer technology for a real leap forward in power
density, noise immunity, and reliability.
With its extremely compact outline of 44mm x 74mm and a total height of typ. 6.5mm, the driver delivers high
power density with an attractive form factor. The component count is reduced by 80% compared to
conventional solutions thanks to the highly integrated SCALE-2 chipset. This results in significantly increased
reliability and reduced costs.

Fig. 4 Recommended user interface of 1SC2060P (primary side)
All ground pins must be connected together with low parasitic inductance. A common ground plane or wide
tracks are strongly recommended. The connecting distance between ground pins must be kept at a minimum.
Description of Primary Side Interface
General
The primary side interface of the driver 1SC2060P is very simple and easy to use.
The driver primary side is equipped with a 10-pin interface connector with the following terminals:
•3 x power-supply terminals
•1 x drive signal input
•1 x status output (fault return)
•1 x input to set the blocking time
All inputs and outputs are ESD-protected. Moreover, all digital inputs have Schmitt-trigger characteristics.
VCC terminal
The driver has one VCC terminal on the interface connector to supply the primary side electronics with 15V.
VDC terminal
The driver has two VDC terminals on the interface connector to supply the DC-DC converters for the
secondary side.
If the driver is used in IGBT mode (see “IGBT and MOSFET operation mode” page 13), VDC should be
supplied with 15V. It is recommended to connect the VCC and VDC terminals to a common +15V power

1SC2060P

supply. In this case the driver limits the inrush current at startup and no external current limitation of the
voltage source for VDC is needed.
If the driver is used in MOSFET mode (see “IGBT and MOSFET operation mode” page 13), VDC should be
supplied with 6V…12V depending on the desired gate voltage and on the load (for a detailed specification,
refer to the driver data sheet /3/).
IN (drive input, e.g. PWM)
IN is the drive input. It safely recognizes signals in the whole logic-level range between 3.3V and 15V. The
input terminal IN features Schmitt-trigger characteristics (refer to the driver data sheet /3/). An input
transition is triggered at any edge of an incoming signal at IN.
SO (status output)
The output SO has an open-drain transistor. When no fault condition is detected, the output SO has high
impedance. An internal current source of 500A pulls the SO output to a voltage of about 4V when leaved
open. When a fault condition (primary side supply undervoltage, secondary side supply undervoltage,
IGBT/MOSFET short-circuit or overcurrent) is detected, the status output SO goes to low (connected to GND).
The diode D1must be a Schottky diode and must only be used when using 3.3V logic. For 5V…15V logic, it can
be omitted.
The maximum SO current in a fault condition must not exceed the value specified in the driver data sheet /3/.
The SO outputs of multiple 1SC2060P can be connected together to provide a common fault signal (e.g. for
one phase). However, it is recommended to evaluate the status signals individually to allow for fast and
precise fault diagnostics.
How the status information is processed
a) A fault on the secondary side (detection of short-circuit of IGBT/MOSFET or supply undervoltage) is
transmitted to the SO output immediately. The SO output is automatically reset (returning to a high
impedance state) after a blocking time Tbhas elapsed (refer to the driver data sheet for timing
information /3/).
b) Supply undervoltage on the primary side is also indicated at the SO output. This fault is automatically
reset (SO returning to a high impedance state) when the undervoltage on the primary side disappears.
TB (input for adjusting the blocking time Tb)
The terminal TB allows the blocking time to be set by connecting a resistor Rbto GND (see Fig. 4). The
following equation calculates the value of Rbconnected between pins TB and GND in order to program the
desired blocking time Tb(typical value):
51][0.1][ +⋅=Ω msTkR bb where 20ms<Tb<130ms and 71k<Rb<181k
The blocking time can also be set to a minimum of 9µs (typical) by selecting Rb=0. The terminal TB must not
be left floating.
Note: It is also possible to apply a stabilized voltage at TB. The following equation is used to calculate the
voltage Vbbetween TB and GND in order to program the desired blocking time Tb(typical value):
02.1][02.0][ +⋅= msTVV bb where 20ms<Tb<130ms and 1.42<Tb<3.62V

Description of Secondary Side Interface
General
The driver’s secondary side is equipped with a 12-pin interface connector with the following terminals:
•2 x DC/DC output terminals VISO
•1 x emitter terminal VE
•1 x reference terminal REF for overcurrent or short-circuit protection
•1x collector sense terminal
•1x active clamping terminal
•2x turn-on gate terminals
•2x turn-off gate terminals
All inputs and outputs are ESD-protected.
DC/DC output (VISO), emitter (VE) and COM terminals
The driver is equipped with blocking capacitors on the secondary side of the DC/DC converter (for values,
refer to the data sheet /3/).
Power semiconductors with a gate charge of up to 3C can be driven without additional capacitors on the
secondary side. For IGBTs or MOSFETs with a higher gate charge, a minimum value of 3µF external blocking
capacitance is recommended for every 1µC gate charge beyond 3µC. The blocking capacitors must be placed
between VISO and VE (C1in Figs. 5 and 6) as well as between VE and COM (C2in Fig. 5). They must be
connected as close as possible to the driver’s terminal pins with minimum inductance. It is recommended to
use the same capacitance value for both C1and C2(IGBT mode). Ceramic capacitors with a dielectric strength
>20V are recommended. Insufficient external blocking can lead to reduced driver efficiency and thus to
thermal overload.
If the capacitances C1or C2exceed 150µF, please contact CONCEPT’s support service.
No static load must be applied between VISO and VE, or between VE and COM. A static load can be applied
between VISO and COM if necessary.
Reference terminal (REF)
The reference terminal REF allows the threshold to be set for short-circuit and/or overcurrent protection with a
resistor placed between REF and VE. A constant current of 150µA is provided at pin REF.
