7.2.1.2 Detailed Design Procedure

The hysteresis vs. resistance curve (Figure 8-2) is used as guidance to set the desired amount of hysteresis.

Figure 8-2 shows that for a 30mV hysteresis, a 150kΩ resistor must be placed from the LE/HYS pin to VEE, as shown in Figure 7-8.

Also possible is to use an external voltage to dynamically program the VHYST. Please see the Adjustable Hysteresis section for more details.
