Description
The TSE2004GB2C0 digital temperature sensor comes with several user-programmable registers to provide maximum flexibility for temperature-sensing applications. The userprogrammable registers specify critical, upper and lower temperature limits, as well as hysteresis settings. Both the limits and hysteresis values are used for communicating temperature events from the chip to the system. This communication is done using the EVENT_n pin, which has an open-drain configuration. The user has the option of setting the EVENT_n pin polarity as either an active-low or active-high comparator output for thermostat operation, or as a temperature event interrupt output for microprocessor-based systems.
