Hi,
I am designing a fairly complex circuit (a hat for a raspberry Pi flight computer) that is doing HDMI -> LVDS conversion, and bringing together various I2C and SPI sources.
Input is from a "12v" glider battery (which could, but not necessarily, be a LiFePO4 battery with 14.8V max nominal...
Basic instruments are mechanical/pneumatic (airspeed, altimeter, mechanical variometer)
Electrically-powered instruments are electric variometer, glide computer (inc GPS), FLARM anti-collision system, radio, and USB power (for GoPros etc). Transponders may eventually be mandated. For cloud...
Thank you very much, that's very helpful.
The LTC4358 looks great (albeit very expensive). Looks like I can probably get away without the hold-up cap as well as the voltage only droops on switchover.
Ideally I could get away with these and do away with the P-Channel MOSFETS altogether...
Hi all,
I've created a circuit that switches individual items of avionics (for my glider) between two 12V batteries with a common ground. The idea is that I can switch items between battery A or B depending on how the batteries (and my power requirements) hold up over the course of a flight...
