8.1.1.2 Short-Circuit Protection and Load wakeup Threshold

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

A design update is planned in the final revision of the IC to extend the minimum threshold down to 20mV. Due to the design update there will be a change of RISCP resistor formula and the revised formula will be as per the Equation 12:

Equation 12. RISCP (Ω)=  ISC×RSNS - 19 mV2 μA
Equation 13. R B Y P A S S   ( Ω ) =   2   μ A   ×   R I S C P   + 19   m V I L W U   -   R D S O N _ B Y P A S S

Lowest SCP threshold setting will be limited to 20mV.
