*** To effectively detect the error occurring at the output port, MBI5027 has a built-in current detection
circuit. The current detection circuit will detect the effective current IOUT, , effective and compare the effective
current IOUT, , effective to the target current IOUT, target, defined by Rext. If IOUT, , effective is much less than the
target current IOUT, target, an error flag will be asserted in the built-in Shift Register. The minimum voltage
requirement for such current detection is VDS, Th1, VDS, Th2, VDS, Th3 and VDS, Th4.
