Tool/software:
In my design I am using DRV8803 low side driver based boards (Redundant boards - two boards in parallel) to drive a single critical relay.
If one of the driver fails as short circuit, Relay will get energied unintentionally and other low side dirver will not have any control.
For such scenario - I would like to know "What are the failure mode of the low side driver output, can it fali as a short(between Source & Drian)". IF YES,
In that case How two low side drivers can be connected in parallel (Redundant manner) to drive a single relay coil. DO I need to add any other additonal circuitary to avoid un-intentional firing of the relay coil.
