Data Sheet
Description
The TS3001GB2A0 digital temperature sensor with accuracy up to
±0.5°C was designed to target applications demanding highest level of
temperature readout.
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.
An additional output open-drain pin, NRST is also sensitive to
temperature thresholds and releases a low pulse after TCRIT
temperature limit has been exceeded followed by TLOW limit crossing.
The sensor uses an industry standard 2-wire, I²C/SMBus serial
interface, and allows up to four devices to be controlled on the bus.
