Other Parts Discussed in Thread: DRV595
Hey E2E NexFET.
Can I use NexFETs for a 6-8V output Buck from 12V?
Sorry if that's a dumb question. The data sheet shows Abs Max on Vin - Vsw & Vsw - Pgnd as being 20V so I don't see why not, but all the TI literature seems aimed at low voltage PoL supplies. Also, the DrMOS bridges seem limited to low voltage outputs.
I want a driven H-bridge to power a TEC (2.2 ohm Thermo-Electric Cooler needing 6.3V at 3.4A). I plan on using either a micro for the PWM signals or a LT1923 (sorry TI), but either way I want to drive a H-bridge with <5V logic and a 12V high-side rail. If I do bi-directional on the TEC (heating as well as cooling), that means this part would have to sink current. Is that ok?
I did find TI's DRV595 and I'm considering altering my design to use it, but it's fairly expensive.
I also found the DRV84x2 which might work.
Thanks for any specific or general advice. Including tips on how I could have answered my own question!
Paul
