Re: half and full bridge chips

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.

We found the STSPIN958.

"Maximum output current up to 5 Arms"?
Has to be a misspelling of Amps I thought.
But table 2.1 does imply Amps rms.

It's been a while since I used Si9978. No surprise it's obsolete now.

What a goofy part number. One of my software
guys wants to play with hardware so we got two eval boards, assuming
he'd blow one up learning. His rig is a nightmare and he's shorted all
sorts of things but it won't blow up. It looks really nice and could
be an audio amp or a servo driver or a TEC driver. It's rated for 500
KHz but he ran it at 1 MHz and it just gets a bit warmer.

The slew rate control and adjustable current limit are slick.

The data sheet is horrible and the eval board is very weird.

Why do some europeans put their data sheets in strange order, like the
table of contents somewhere near the end?
