5.1.2 Remote Sensing (2-wire or 4-wire Connection)
5-3
NOTE: Maximum remote sensing voltage (tolerable voltage difference between OUTPUT and SENSE) is ± 1.0 V
at both HI and LO sides.
Maintain the following restriction for r1 to r4 to satisfy the specified accuracy.
r
1, r2 ≤ 1.0 V/Io [ Ω ]
(Io: Output current)
r3, r4 ≤ × 220 k Ω [ Ω ]
(Vos = r
1Io, r2Io)
(Example) If Io = 0.5 A
r
1, r2 ≤ 1.0 V/0.5 A = 2 Ω
r1, r2 = 2 Ω
then,
r3, r4 ≤ × 220 k Ω = 2.2 Ω
