I am looking for a high sided switch IC to control the power outputs to 2 independent power channels (loads). One channel needs to limit to 1A and the other 0.5A.
Digging around it looks like the TPS2HB50-Q1 device that you are currently showing in preview may do the job.

The online data is a bit vague at the moment so I wondered if you can fill in some gaps?
- When is the part due for production release – I want to run the loads at a nominal 24Vdc so does this mean I need the TPS2TB50??
- Any idea of cost for the version I want - TPS2TB50 is this is the part number for the 24Vdc version ?
- Can both channels current output limit be individually set (i.e. one at 500mA and the other at 1A)?
- What is the sense output and how is it multiplexed between channels (i.e. for current measure)?
- What is the latch pin?
Are there any other devices that I should look at (one with I2C control would be nice)?
