In application note AN4355, overcurrent detection page 18 and stall detection page 21, application note writes two equations
Equation 1: IOCDth = VOCDth × Rds(ON)
Equation 2: ISTALLth = VSTALLth × Rds(ON)

Why current is equal to voltage times resistance?
should be use divide sign IOCDth = VOCDth ÷ Rds(ON)

How should I calculate overcurrent IOCDth ?
for an instance, by default, IOCDth is 281.25mV, and external MOSFET Rds(ON) is 33mΩ, what is IOCDth equal to ?

Thank you in advance
