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.
