NOTE: Theoretical switching point of the OVER-CURRENT SENSE input is one half of the power supply determined by an internal bias
network in manufacturing. Tolerances cause the switching point to vary ± 0.25V. After manufacture, the switching point remains fixed within
10mV over time and temperature. The input switching sensitivity is a maximum of 50mV. There is no hysteresis on the OVER-CURRENT
SENSE input.
