Functional Description
3.1
Introduction
The 1EDIxxI12AH and 1EDIxxH12AH are general purpose IGBT gate drivers. Basic control and protection features
support fast and easy design of highly reliable systems.
The integrated galvanic isolation between control input logic and driving output stage grants additional safety.
Its wide input voltage supply range supports the direct connection of various signal sources like DSPs and
microcontrollers.
The separated rail-to-rail driver outputs simplify gate resistor selection, save an external high current bypass
diode and enhance dV/dt control.

With bipolar supply the driver is typically operated with a positive voltage of 15 V at VCC2 and a negative
voltage of -8 V at GND2 relative to the emitter of the IGBT. Negative supply can help to prevent a dynamic turn
on due to the additional charge which is generated from IGBT’s input capacitance.

Figure 4 Application Example Unipolar Supply
For unipolar supply configuration the driver is typically supplied with a positive voltage of 15 V at VCC2. In this
case, careful evaluation for turn off gate resistor selection is recommended to avoid dynamic turn on.
