DM2190P-B

The MD2190P-B driver is a two–channel driver for high-power field-effect transistors (MOSFET or IGBT), designed for galvanically isolated control of two high-power transistors with a maximum allowable voltage of up to 1700 V. The driver is an amplifier that generates transistor gate control signals with a frequency of up to 100 kHz. The driver contains a built-in galvanically isolated DC/DC converter that provides the necessary levels of unlocking and locking voltages at the transistor gates.

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

unlocking and locking of controlled transistors according to control signals;

saturation voltage monitoring on the collector of the controlled transistor, its smooth shutdown when exiting the saturation state;

emergency control lock with lock duration adjustment;

alarm about the presence of an emergency situation;

no blocking of simultaneous activation in independent mode;

blocking simultaneous activation of the upper and lower arms in dependent mode;

adjustable delay for switching the upper and lower arms;

gate bypass in the off state ("Miller Clamp");

power supply plus 5 V for the external control circuit;

monitoring of supply voltages at the output of the DC/DC converter.
