Description
The TS3000B3A 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 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.
The sensor uses an industry standard 2-wire, I
interface, and allows up to eight devices to be controlled on the bus.
