Typ. Short circuit detection level

Conditions:

Vs=12V

Parameter:

Typ. Gate voltage limitation during short circuit detection

Conditions:

Vs=12V; Load at output: capacitor with 22nF; V(SHx) = GND; V(SLx) = GND;

For HS (high-side output); Short happens during on phase V(VDH)-V(SHx)=3V;

For LS (low-side output); Short happens during on phase V(SHx)-V(SLx)=3V;

Parameter:
