TMP144 Low-Power, Digital Temperature Sensor With SMAART Wire™ / UART

Interface

1 Features

3 Description

•

Multiple Device Access (MDA):

– Global read/write operations

SMAART Wire™ / UART interface

Resolution: 12-bit or 0.0625 °C

±1 °C maximum (–10 °C to +100 °C)

±2 °C maximum (–40 °C to +125 °C)

Low quiescent current:

– 3-μA active I_Qat 0.25 Hz

– 0.6-μA shutdown

Supply range: 1.4 V to 3.6 V

Push-pull digital output

The TMP144 digital output temperature sensor can

read temperatures to a resolution of 0.0625 °C.

•

The device has

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.

•

Package:

The TMP144 device is designed for space-

constrained, 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 two 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.

– 0.76 mm × 0.96 mm, 150-µm maximum height,

4-ball YMT (DSBGA)

– 0.76 mm × 0.96 mm, 625-µm maximum height,

4-ball YFF (DSBGA)
