I have had the bellow circuit designed with the intention of switching the high side of a 12v automotive relay:
Now I've realised I need the option to switch the low side of relays, as sometimes I have no access to the live wiring or can't control it.
However I don't want to add any extra connectors, so I need to have one output pin that switches between high(14v) and low. (I think the correct term would be a half bridge?)
Can I just add a BTS3134N like the following:
The FPF2700 is active low and the BTS3134N seems to be active high so it would be impossible for them to be turned on at the same time.
Or could I use a H bridge IC such as the L6206Q which lets me control both outputs to High, Low and High impedance. But i'm concerned as I'm not sure if it is designed to supply current from both outputs at the same time.
