I'm designing some products that need 48-volt half or full-bridge
drivers. Not just gate drivers but the whole thing.

We tried the TI DRV8962. It has lots of voltage and current range and
has four half bridges, but its shoot-through power dissipation is high
and limits its frequency to about 200 KHz.

Has to be a misspelling of Amps I thought.
But table 2.1 does imply Amps rms.

For serious power, we use a gate driver chip and discrete mosfets.
UCC27712 is nice.
