Operating mode « F out»
The driver is in a working state if the output of the contact «F out» is logical 1 (+15). If the contact output contains F
out logic 0 (0 V), the driver is in an error state for one or more of the following reasons:
1. Channel A is in error.
2. Channel B is in error.
3. Driver supply voltage below minimum (+13.7 V)

Operating mode “F out A / B”
Output of channel A / B has logic “1” (+15 V) in normal state. If the output of the contact F out A / F out B has logic 0
(0 V), the driver is in an error state for one or more of the following reasons:
1. Reduced voltage of the secondary side of the channel A / B
2. The DESAT circuit has triggered (collector-emitter voltage is more than + 8V or is open circuit.)

Selects the level of the Signal A / B control input signals
To select the amplitude of the input control signals Signal A and Signal B, you must set jumper JP1 to 15 V or 5 V.

Operation mode selection
If jumper JP2 is closed, then the “direct” mode is selected – that is, channel A and channel B are independent of each
other and can be turned on simultaneously.
If jumper JP2 is open, then the “half-bridge” mode is selected — that is, the simultaneous activation of channel A and
channel B. A delay (dead time tDT) of 3.2 μs appears between channel state switching.

Operating mode of UVLO
If the VCC supply voltage drops below +13.7 V, the driver will go into an error state and block the control. To exit the
error state, the VCC supply voltage must be raised to +14.5 V.

DESAT circuit mode
The DESAT circuit is a protective driver circuit that protects the IGBT module from high-amplitude currents. A circuit
with a delay of 8 μs after the start of switching on the IGBT starts monitoring the voltage drop of the IGBT transistor between
the collector-emitter terminals. If the voltage drop exceeds the value + 8V, the driver will turn off the IGBT module with a
delay of 350 ns using the “soft” shutdown function with next blocking the input control signals. The outputs of the F out A / B
driver and F out will be put into an error state.
