Description

The TS3000GB0A0 digital temperature sensor with accuracy up to

±0.5°C was designed to target applications demanding highest level of

temperature readout. The sensor is fully compliant with JEDEC JC42.4

Component Specification.

The digital temperature sensor comes with several user-programmable

registers to provide maximum flexibility for temperature-sensing

applications. The registers allow specifying 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 pin,

which has an open-drain configuration. The user has the option of setting

the Event 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.

interface, and allows up to eight devices to be controlled on the bus.
