SSM2211 short protected ?

Hi ChrisDan ,

We can use the Shutdown pin of the SSM2211 to shutdown the part when a short circuit protection occurs. It can be implemented by using a current sense resistor and current sense amplifier on the output. The current sense amplifier will then detect the current reading and by setting your preferred output limit current, it will be fed back to the shutdown pin to tell the SSM221 to shut down. Additional parts may be added to the feedback loop such as comparator to toggle the shutdown pin.

Thanks and regards,

JE

Hi jeobico, thanks for your answer. Yes, meanwhile - as you already mentioned in principle  - i'll use a AD8418 current sense amplifier and a comparator (including reference) to drive the shutdown pin of the SSM2211, at the present time only simulated by LTSpice, let's see if it may work in reality ;-)

Have a nice time

Christian
