'[EE] Interesting Chip supplier.'

Have some interesting chips.

HV7800 High Side Current sense (to 450V) is what I saw advertised and
interested me.

Various LED driver chips.

MD1810/1 Quad MOSFET drivers for Piezo transducers, CCD chips, level
shifting, etc.

Looks like they also have hot swap controllers, PoE chips, LED and
Luminescent driver chips, High and Low side driver/interface chips, along
with discrete enhancement and depletion mode FETs and IBBTs.

I, too was impressed with that, including 1% tolerances! A very
interesting chip, in
SOT23-5. Apparently it can be used to measure current in a VCC branch!

Anybody see how much they are?

Yes, their line of depletion mode MOSFETs are extremely useful for some
kinds of analog circuits.

And Mouser now stocks some of their parts.
