2.1
The 2ED020I12FA 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 driver. The input can be directly connected to a standard 5V DSP or
microcontroller with CMOS in/output and the output driver are connected to the high side and low side switch.
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.
