The sense comparator output SO is an open collector. An appropriate external pull-up
resistor is typ. 5.6 kΩ … 47 kΩ, the minimum value of 5.6 kΩ being defined by the max.
sink current capability of the SO output transistor. If the sense comparator is not used
the pull-up resistor can be spared. In this case the SI pin should be directly connected to
Q1 in order to keep the comparator inactive.
