Wiring electronic E-Brake

PMU
1

Apologies if this has been covered. Is it possible to wire two outputs to engage and disengage a 2 wire electronic e-brake without using external relays. Typically I wire them through a pair of NO/NC relays so when one wire is active (+12V) the other is ground. I would like to use two outputs but would need them to be NC to ground, there by when one output is active the circuit is complete. hope that makes sense. Then I could use some math inside the PMU for current overrides and time delays.

Thanks

I think you need dual h bridge for that if you want to remove relays .

You will need to use ECU Master dual half bridge module to do that.

What I would like to know is: how much current draw when the caliper is locked is considered safe to stop apliying power.

Using the half bridge I think it would be possible to control power windows as well, and I think the safety strategies would be doable as well.
