10.1.1.2 Short-Circuit Protection Threshold

The minimum short-circuit protection threshold is limited to 30 mV.

A design update is planned in the final revision of the IC to extend the minimum threshold down to 20 mV. Due to the design update there will be a change of RSCP resistor formula and the revised formula will be as per the Equation 9:

Equation 9. RSCP (Ω)=  ISC×RSNS - 19 mV2 μA

Lowest SCP threshold setting will be limited to 20 mV.
