UC2625 Gate Driver

Other Parts Discussed in Thread: UC2625, LM5107, DRV8307, DRV8308

Hi,

I am trying to use UC2625 in a design. Planning to drive N-channel MOSFETs on high and low-sides.

UC2625 PU outputs are in open-drain configuration, PD outputs are something like push-pull or totem-pole. (PU active low, PD active high)

Are there any gate drivers, to accept these two inputs? Or what kind of gate driver should I implement?

Thanks!

Hi Eray,

For gate drivers, have you looked at the LM5107? You may need additional circuitry to invert the signal.

Also, have you investigated using the DRV8307 or DRV8308? Depending on the voltage range this may meet your needs.

Hello Rick,

Thanks for your reply. I use UC2625 since it is a Controlled Assembly / Enhanced Product.

So, if I use a LM5100 series gate driver, I should invert (only) PU outputs using an N type Mosfet. Did I get it right?

Regards..

Thanks Luis. By the way, are there any evaluation boards or example schematics for UC2625 ?
