1.

Do not mounted (DNM).

2.

R6 must be removed if R7 is soldered.

3.

Better performances can be obtained using part number B82477G4473M003 (DCR = 52m

Ω)

4.

Default value to sense 50 mV @10 A max.

5.

Two threshold is suited: # 2.5 V for SEA05: R17=3M

Ω, R18+R19=287kΩ => Vmax=28.8 V # 1V for SPV1020: R17+R18=3.187 , R19=100kΩ => Vmax= 35 V.
