DESCRIPTION

The TMP100 and TMP101 are two-wire, serial output

temperature sensors available in SOT23-6 packages.

Requiring no external components, the TMP100 and

TMP101 are capable of reading temperatures with a

resolution of 0.0625°C.

The TMP100 and TMP101 feature SMBus and I

interface compatibility, with the TMP100 allowing up to

eight devices on one bus. The TMP101 offers SMBus alert

function with up to three devices per bus.

The TMP100 and TMP101 are ideal for extended

temperature measurement in a variety of communication,

computer, consumer, environmental, industrial, and

instrumentation applications.

The TMP100 and TMP101 are specified for operation over

a temperature range of −55°C to +125°C.

The TMP100 and TMP101 are I2C and SMBus interface-compatible and are specified over a temperature range of −55°C to +125°C. The TMP100 and TMP101 require no external components for operation except for pull-up resistors on SCL, SDA, and ALERT, although a 0.

" #$$ " #$# www.ti.com SBOS231G − JANUARY 2002 − REVISED NOVEMBER 2007 SERIAL BUS ADDRESS To program the TMP100 and TMP101, the master must first address slave devices via a slave address byte. The slave address byte consists of seven address bits, and a direction bit indicating the intent of executing a read or write operation. The TMP100 features two address pins to allow up to eight devices to be addressed on a single I2C interface.

The master acknowledges reception of the data byte. The master may terminate data transfer by generating a Not-Acknowledge on reception of any data byte, or generating a START or STOP condition. SMBus ALERT FUNCTION The TMP101 supports the SMBus Alert function.

The receiver acknowledges the transfer of data. The TMP100 and TMP101 are I2C and SMBus compatible. Figure 5 to Figure 8 describe the various operations on the TMP100 and TMP101. Bus definitions are given below. Parameters for Figure 5 are defined in Table 13.
