IO = 200 mA (upper side + lower side)

IO = 400 mA (upper side + lower side)

IVref = 1 mA

Resistance between VCC and VM = 1 Ω,

when LIR = 2 V

VIN = 5 V

IO = 1 mA

Output current limit is determined by the following equation (Rf is the sensing resistance between VCC and VM):

Ilimit = VLIR/10Rf (A)

The input range for VLIR is 0.5 to VCC–1.0 (V)
