Pin Functionality
GND1
Ground connection of the input side.
IN+ Non Inverting Driver Input
IN+ control signal for the driver output if IN- is set to low. (The IGBT is on if IN+ = high and IN- = low)
A minimum pulse width is defined to make the IC robust against glitches at IN+. An internal Pull-Down-Resistor
ensures IGBT Off-State.
IN- Inverting Driver Input
IN- control signal for driver output if IN+ is set to high. (IGBT is on if IN- = low and IN+ = high)
A minimum pulse width is defined to make the IC robust against glitches at IN-. An internal Pull-Up-Resistor
ensures IGBT Off-State.
/RST Reset Input
Function 1: Enable/shutdown of the input chip. (The IGBT is off if /RST = low). A minimum pulse width is defined
to make the IC robust against glitches at /RST.
Function 2: Resets the DESAT-FAULT-state of the chip if /RST is low for a time TRST. An internal Pull-Up-Resistor
is used to ensure /FLT status output.
/FLT Fault Output
Open-drain output to report a desaturation error of the IGBT (FLT is low if desaturation occurs)
RDY Ready Status
Open-drain output to report the correct operation of the device (RDY = high if both chips are above the UVLO level
and the internal chip transmission is faultless).
VCC1
5 V power supply of the input chip
VEE2
Negative power supply pins of the output chip. If no negative supply voltage is available, all VEE2 pins have to be
connected to GND2.
DESAT Desaturation Detection Input
Monitoring of the IGBT saturation voltage (VCE) to detect desaturation caused by short circuits. If OUT is high, VCE
is above a defined value and a certain blanking time has expired, the desaturation protection is activated and the
IGBT is switched off. The blanking time is adjustable by an external capacitor.
CLAMP Miller Clamping
Ties the gate voltage to ground after the IGBT has been switched off at a defined voltage to avoid a parasitic
switch-on of the IGBT.During turn-off, the gate voltage is monitored and the clamp output is activated when the
gate voltage goes below 2 V below VEE2.

Functional Description
4.1
Introduction
The 1ED020I12-F2 is an advanced IGBT dual gate driver that can be also used for driving power MOS devices.
Control and protection functions are included to make possible the design of high reliability systems.
The device consists of two galvanic separated parts. The input chip can be directly connected to a standard 5 V
DSP or microcontroller with CMOS in/output and the output chip is connected to the high voltage side.
The rail-to-rail driver outputs enables the user to provide easy clamping of the IGBTs gate voltage during short
circuit of the IGBT. So an increase of short circuit current due to the feedback via the Miller capacitance can be
avoided. Further, a rail-to-rail output reduces power dissipation.
The device also includes IGBT desaturation protection with FAULT status outputs.
Two READY status outputs reports if the device is supplied and operates correctly.

The driver 1ED020I12-F2 is designed to support two different supply configurations, bipolar supply and unipolar
supply.
In bipolar supply the driver is typically supplied with a positive voltage of 15V at VCC2 and a negative voltage of
-8V at VEE2, please refer to Figure 4. Negative supply prevents a dynamic turn on due to the additional charge
which is generated from IGBT input capacitance times negative supply voltage. If an appropriate negative supply
voltage is used, connecting CLAMP to IGBT gate is redundant and therefore typically not necessary.
For unipolar supply configuration the driver is typically supplied with a positive voltage of 15V at VCC2. Erratically
dynamic turn on of the IGBT could be prevented with active Miller clamp function, so CLAMP output is directly
connected to IGBT gate, please refer to Figure 5.

Internal Protection Features
4.3.1
Undervoltage Lockout (UVLO)
VEE2
To ensure correct switching of IGBTs the device is equipped with an undervoltage lockout for both chips, refer to
Figure 9.
If the power supply voltage VVCC1 of the input chip drops below VUVLOL1 a turn-off signal is sent to the output chip
before power-down. The IGBT is switched off and the signals at IN+ and IN- are ignored as long as VVCC1 reaches
the power-up voltage VUVLOH1.
If the power supply voltage VVCC2 of the output chip goes down below VUVLOL2 the IGBT is switched off and signals
from the input chip are ignored as long as VVCC2 reaches the power-up voltage VUVLOH2. VEE2 is not monitored,
otherwise negative supply voltage range from 0 V to -12 V would not be possible.
4.3.2
READY Status Output
The READY outputs shows the status of three internal protection features.
•
•
•
UVLO of the input chip
UVLO of the output chip after a short delay
Internal signal transmission after a short delay
It is not necessary to reset the READY signal since its state only depends on the status of the former mentioned
protection signals.
4.3.3
Watchdog Timer
During normal operation the internal signal transmission is monitored by a watchdog timer. If the transmission fails
for a given time, the IGBT is switched off and the READY output reports an internal error.
4.3.4
Active Shut-Down
The Active Shut-Down feature ensures a safe IGBT off-state if the output chip is not connected to the power
supply, IGBT gate is clamped at OUT to VEE2.

Functional DescriptionNon-Inverting and Inverting Inputs
4.4
Non-Inverting and Inverting Inputs
There are two possible input modes to control the IGBT. At non-inverting mode IN+ controls the driver output while
IN- is set to low. At inverting mode IN- controls the driver output while IN+ is set to high, please see Figure 7. A
minimum input pulse width is defined to filter occasional glitches.
4.5
Driver Outputs
The output driver sections uses only MOSFETs to provide a rail-to-rail output. This feature permits that tight control
of gate voltage during on-state and short circuit can be maintained as long as the drivers supply is stable. Due to
the low internal voltage drop, switching behaviour of the IGBT is predominantly governed by the gate resistor.
Furthermore, it reduces the power to be dissipated by the driver.
4.6
External Protection Features
4.6.1
Desaturation Protection
A desaturation protection ensures the protection of the IGBT at short circuit. When the DESAT voltage goes up
and reaches 9 V, the output is driven low. Further, the FAULT output is activated, please refer to Figure 8. A
programmable blanking time is used to allow enough time for IGBT saturation. Blanking time is provided by a
highly precise internal current source and an external capacitor.
4.6.2
Active Miller Clamp
In a half bridge configuration the switched off IGBT tends to dynamically turn on during turn on phase of the
opposite IGBT. A Miller clamp allows sinking the Miller current across a low impedance path in this high dV/dt
situation. Therefore in many applications, the use of a negative supply voltage can be avoided.
During turn-off, the gate voltage is monitored and the clamp output is activated when the gate voltage goes below
typical 2 V (related to VEE2). The clamp is designed for a Miller current up to 2 A.
4.6.3
Short Circuit Clamping
During short circuit the IGBTs gate voltage tends to rise because of the feedback via the Miller capacitance. An
additional protection circuit connected to OUT and CLAMP limits this voltage to a value slightly higher than the
supply voltage. A current of maximum 500 mA for 10 μs may be fed back to the supply through one of this paths.
If higher currents are expected or a tighter clamping is desired external Schottky diodes may be added.
4.7
RESET
The reset inputs have two functions.
Firstly, /RST is in charge of setting back the FAULT output. If /RST is low longer than a given time, /FLT will be
cleared at the rising edge of /RST, refer to Figure 8; otherwise, it will remain unchanged. Moreover, it works as
enable/shutdown of the input logic, refer to Figure 7.

Reference Layout for Thermal Data
The PCB layout shown in Figure 11 represents the reference layout used for the thermal characterisation. Pins 9
and 16 (GND1) and pins 1 and 8 (VEE2) require ground plane connections for achiving maximum power
dissipation. The 1ED020I12-F2 is conceived to dissipate most of the heat generated through this pins.

Printed Circuit Board Guidelines
Following factors should be taken into account for an optimum PCB layout.
•
•
•
•
Sufficient spacing should be kept between high voltage isolated side and low voltage side circuits.
The same minimum distance between two adjacent high-side isolated parts of the PCB should be maintained
to increase the effective isolation and reduce parasitic coupling.
In order to ensure low supply ripple and clean switching signals, bypass capacitor trace lengths should be kept
as short as possible.
Lowest trace length for VEE2 to GND2 decoupling could be achieved with capacitor closed to pins 1 and 3.
