H-bridge Driver Chip

Hello. I am looking at designing an H-bridge circuit for driving Peltiers in heat and/or cool mode. It will run at either 12V or 24V (not selected yet) and up to 20 amps. It will probably be used in a PWM controller.

I came upon the Intersil HIP4081, which provides the drive to external N-channel MOSFETs. Sounds good, so far, and it is available at DigiKey at a decent price..

My question is this: Does anyone have experience with this device? Is there something newer out there that I should look at?

Also, DigiKey carries an evaluation board for this, but it looks like it uses P-channel MOSFETs. Anyone tried this before?

Thanks for your inputs.
