DM1120P-A1

The MD1120P-A1 driver is a single–channel MOSFET and IGBT transistor driver designed for galvanically isolated control of a powerful field-controlled transistor with maximum permissible currents and voltages of 600V/600A, 1200V/400A, 1700V/400A with an additional "Status" output. The driver has a built–in DC/DC converter and is an amplifier - generator of transistor gate control signals with a frequency of up to 25 kHz.

The driver provides the following control, monitoring and protection functions for the controlled transistor:

transistor control according to control signals;

formation of galvanically isolated voltages for unlocking and locking a controlled transistor control of the saturation voltage on the collector of a controlled transistor, its protective shutdown when exiting the saturation state;

ensuring a smooth transition of the driver from the active state to the inactive state in case of an accident (output of the controlled transistor from saturation mode);

blocking the control in case of an accident;

setting the delay in triggering the unsaturation protection;

setting the duration of the smooth emergency shutdown of the controlled transistor;

an alarm about the presence of an accident.
