DR2180P-B7

The DR2180P-B7 driver (hereinafter referred to as the driver) is a two–channel driver of high–power field-controlled transistors (MOSFET or IGBT), designed for dependent galvanically isolated control of two high-power transistors with a maximum permissible voltage of up to 3300 V. The driver is an amplifier – generator of gate control signals of transistors 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 gate of the transistor. The driver provides the following control, monitoring and protection functions for the controlled transistor:

1. monitoring of the saturation voltage on the collector of the controlled transistor, its protective shutdown when exiting the saturation state;
2. ensuring a smooth transition of the driver from the active state to the inactive state in case of an emergency (output of the controlled transistor from saturation mode);
3. blocking the control in case of an emergency;
4. alarm about the presence of an emergency situation;
5. adjustment of the on-off current of the controlled transistor by changing the resistance of the resistors in the output circuit (Ron, Roff);
6. blocking the simultaneous activation of the upper and lower arm;
7. the delay in switching the upper and lower arms;
8. adjustment of the delay for switching the upper and lower arm;
9. monitoring of driver supply voltages (built-in comparators) at the output of the DC/DC converter.
