Description
The 1ED020I12FTA is a galvanic isolated single channel IGBT driver in PG-DSO-20 package that provides an
output current capability of typically 2A.
All logic pins are 5V CMOS compatible and could be directly connected to a microcontroller.
The data transfer across galvanic isolation is realized by the integrated Coreless Transformer Technology.
The 1ED020I12FTA provides several protection features like IGBT two level turn off, desaturation protection, active
Miller clamping and active shut down.

4.3.1 Undervoltage Lockout (UVLO)
To ensure correct switching of IGBTs the device is equipped with an undervoltage lockout for both chips, refer
to Figure 7-8 and Figure 7-9.
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 output at pin /RDY 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.
