SBOS488E June 2009 – December 2018 TMP302
Designing with the TMP302 family of devices is simple. The TMP302 family of devices is a temperature switch commonly used to signal a microprocessor in the event of an over temperature condition. The temperature at which the TMP302 family of devices issues an active low alert is determined by the configuration of the TRIPSET0 and TRIPSET1 pins. These two pins are digital inputs and must be tied either high or low, according to Table 1. The TMP302 family of devices issues an active low alert when the temperature threshold is exceeded. The device has built-in hysteresis to avoid the device from signaling the microprocessor as soon as the temperature drops below the temperature threshold. The amount of hysteresis is determined by the HYSTSET pin. This pin is a digital input and must be tied either high or low, according to Table 2.
