Tolerances cause the switching point to vary plus or minus .25 Volts. After manufacture, the switching point remains fixed within 10 mV over time and temperature. The input switching sensivity is a maximum of 50mV. There is no hysteresis on the OVERCURRENT SENSE input.

The OVERCURRENT is sensed continuously, and sets a flip flop which is reset by the rising edge of the ENABLE input or the sawtooth OSCILLATOR.
