The hysteresis pin has two settings. Grounding HYSTSET results in 5°C of hysteresis. Connecting HYSTSET to VS results in 10°C of hysteresis. Hysteresis error variation over temperature is shown in Figure 12 and Figure 13.
Use bypass capacitors on the supplies as well as on the RSET and analog out (VTEMP) pins when in noisy environments, as shown in Figure 14. These capacitors reduce premature triggering of the comparator.
