PRODUCTION DATA
7.2.5 Hysteresis
The hysteresis pin has two settings. Grounding HYSTSET results in 5°C of hysteresis. Connecting HYSTSET to VS results in 10°C of hysteresis. Figure 7-5 and Figure 7-6 show the hysteresis error variation over temperature.
Figure 7-5 5°C Hysteresis Error vs Temperature
Figure 7-6 10°C Hysteresis Error vs TemperatureUse bypass capacitors on the supplies as well as on the RSET and analog out (VTEMP) pins when in noisy environments, as shown in Figure 7-7. These capacitors reduce premature triggering of the comparator.
