3 Description

The TMP144 digital output temperature sensor can

read temperatures to a resolution of 0.0625°C.

The device has a SMAART Wire™ / UART

interface that supports daisy-chain configurations. The

interface also supports Multiple Device Access (MDA)

commands that let the host communicate with multiple

devices on the bus simultaneously. MDA commands

are used as an alternative to sending individual

commands to each device on the bus. Up to 16

TMP144 devices can be attached together serially

and can be read by the host computer.

The TMP144 device is designed for spaceconstrained,

power-sensitive applications with multiple

temperature measurement zones that must be

monitored. The device is specified for operation over

a temperature range of –40°C to 125°C and is

available in three different 4-ball, low-height wafer

chip-scale package (DSBGA) options. The YMT

package of the device has a height of 150 μm, which

is 40 thinner than a 0201 resistor. The thinner

YMT package can be placed under heat-dissipating

components on the system for better accuracy and

faster thermal response times.
