7.3.1 HYSTSET

If the temperature trip threshold is crossed, the open-drain, active low output (OUT) goes low and does not return to the original high state (that is, VS) until the temperature returns to a value within a hysteresis window set by the HYSTSET pin. The HYSTSET pin allows the user to choose between a 5°C and a 10°C hysteresis window. Table 2 lists the hysteresis window that corresponds to the HYSTSET setting.

Table 2. HYSTSET Window

HYSTSET THRESHOLD HYSTERESIS
GND 5°C
VS 10°C

For the specific case of the device, if the HYSTSET pin is set to 10°C (that is, connected to VS) and the device is configured with a 60°C trip point (TRIPSET1 = VS, TRIPSET0 = GND), when this threshold is exceeded the output does not return to the original high state until it reaches 50°C. This case is more clearly shown in Figure 9.
