The MD270P-B driver is a two–channel driver of high-power field-controlled transistors (MOSFET or IGBT), designed for galvanically isolated dependent or independent control of two high-power transistors with a maximum permissible voltage of up to 1700 V. The driver is an amplifier – generator of gate control signals of transistors with a frequency of up to 50 kHz. The driver contains a built-in galvanically isolated DC/DC converter that provides the necessary levels of unlocking and locking voltages at the gate of the transistor.
The driver provides the following control, monitoring and protection functions for the controlled transistor:
- Unlocking and locking of controlled transistors in accordance with the with control signals;
- Control of the saturation voltage on the collector of the controlled transistor, its protective shutdown when exiting the saturation state;
- Blocking the control in case of an emergency;
- Alarm about the presence of an emergency situation;
- Blocking the simultaneous activation of the upper and lower arm in dependent mode and the absence of blocking in independent mode;
- Delay in switching the upper and lower arms in dependent mode;
- Control of the supply voltage of the driver and the output of the DC/DC converter.
