DGD44175

Description

The DGD44175 is a low-side IGBT gate driver capable of driving 2.6A of peak current. The DGD44175 logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with MCUs and have a -10Vdc max capability for increased ruggedness on input line.

The OCP function has a -0.25V threshold that turns off the ouputs and brings EN/FLT* to 0V as a fault indicator; also the same pin EN/FLT* can be externally controlled to enable and disable the device. A UVLO turns off the outputs when VCC falls below UVLO threshold and also engages FLT* to L.

The DGD44175 is offered in the TSOT26 package and the operating temperature extends from -40°C to +125°C.
