Poll: What Was The Last Robust Protection Circuit You Designed?

Analog systems are omnipresent today, and system designers embed robust protection devices to ensure that these systems operate correctly in diverse and extreme conditions to fulfill their designated functional life-cycle. Reliable protection devices maintain and monitor systems' environments, confirming safety and performance for mission-critical applications. Robust protection, at its simplest, is the intentional addition of a 'link' in a circuit to protect and safeguard the system in the event of a fault – whether due to temperature variations, excessive current, overvoltage flow, or transients.

    I just had my fail of the day moment, reading the title as:

    Can't vote because it would be misleading, recent projects have included ALL of the above.

     

    However, to try and be more helpful, pretty much everything has EMI/ESD protection or mitigation.

     

    But most serious…

    I'm certainly not going to talk about that !

    Reverse polarity is pretty common ... would have probably been the last thing I've had to incorporate into a design.

    Protect the asynchronous transmission system by isolating it from transients or faults introduced by the external world.

    But most serious projects for production will have hardware/software malfunction protection, low voltage protection (so the processor stops ).

     

    Anything using much power will have over current and maybe over temperature protection.

     

    High transient protection is essential on anything mains powered (even indirectly via a power brick) but maybe not on battery powered things.
