*2. I_LIM:
Actual limit current
I_LIM(S): Set limit current
Attention should be paid to the power dissipation when the output current is large.
*3. I_SHORT: Actual load short-circuit detection current
I_SHORT(S): Set load short-circuit detection current
*4. I_OPEN: Actual load open detection current
I_OPEN(S): Set load open detection current
*5. Only the variation of the IC is considered. The variation of the external shunt resistor (R_SHUNT) and the sense
resistor (R_SENSE) are not included.
