What issues would one encounter by using a gate driver IC to directly drive a load instead of using it to drive transistors?
For consideration would be the very affordable Infineon 2EDN752x series dual low-side gate driver capable of 5A source and sink. The load would be inductive - a Wurth 732-2909-ND flyback transformer stepping the voltage up from 12v to about 140-180v. The transformer will be driven at a frequency range between 20kHz and 80kHz and a 25% duty cycle of 1s (250ms on 750ms off). Current draw will average less than 300mA.
What would be the issues of utilizing such a device as a full-bridge "in-and-of-itself" by connecting the outputs in series with the load and adding appropriate external protection such as flyback diodes?
This is specific to the Infineon 2EDN752x series of gate drivers, but it can just be considered as a starting point for this discussion. Click here for the datasheet.
