For a one-off test box I need an H-bridge capable of 48V and 2A. I'd like to drive it with 3.3V logic. Cost is by and large irrelevant. Any suggestions? Thanks.

EDIT: The motor drive PWM freq. will be 16kHz.

For example, just poking around I found this hi/lo side driver IC

Looks like 2 of these and 4 mosfets will do the job. No idea if there are better/easier solutions, but I'll keep poking.

I've used the TI DRV8412 on a few projects.
