Under Voltage Protection (UVP) primary
The internally detected supply voltage of the driver has an under voltage protection. The table below gives an
overview of the trip level.
If the internally detected supply voltage of the driver falls below this level, the IGBTs will be switched off (IGBT
driving signals set to LOW). The input side switching signals of the driver will be ignored. The error memory will
be set, and the output PRIM_HOLD_OUT changes to the HIGH state.
Under Voltage Protection secondary
This function monitors the rectified voltage on the secondary side. If the voltage drops, the IGBTs will be switched
off (IGBT driving signal set to LOW). The input side switching signals of the driver will be ignored. No failure
message will be generated.
Input Signals
The signal transfer to each IGBT is made with pulse transformers, used for switching on and switching off of the
IGBT. The inputs have a Schmitt Trigger characteristic and a positive / active high logic (input HIGH = IGBT on;
input LOW = IGBT off).
It is mandatory to use circuits which switch active to +15V and 0V. Pull up and open collector output stages must
not be used for TOP / BOT control signals. It is recommended choosing the line drivers according to the
demanded length of the signal wires.

A capacitor is connected to the input to obtain high noise
immunity. This capacitor can cause for current limited line
drivers a little delay of few ns, which can be neglected. The
capacitors have to be placed as close as possible to the
driver interface.
