4. Functional Description

The T06 family of I2C temperature sensors measure and digitize the local temperature at the device. 4 modes

of operation are possible:

Sleep Mode

This ultra-low power mode of operation is useful when temperature measurements are made infrequently and

the lowest possible power is desired. In this mode, the part will remain in sleep mode until it receives a

command over I2C to wake up and make a measurement. After this measurement, the part will go back to

sleep.

The sleep bit is the ‘master’ bit. Once this bit is set, the sensor enters its sleep mode regardless of the other

register configurations. Once the part is woken up by I2C, all registers are loaded to their default value, except

for 0xC6 and 0xC7, which can be saved by the usestore bit.

How to Configure:

sleep = 1

stop = X

sltimeena = X

Autonomous Sampling Mode

In this mode of operation, the device will make measurements at a factory set rate of 5 Hz (every 200 ms). By

default the part enters the Autonomous Sampling Mode upon power-up. The sensor wakes up, performs a

temperature conversion, updates the output accordingly, and then goes back to sleep.

How to Configure:

sleep = 0

stop = 0

sltimeena = 1 (default state after wake-up)

Active Mode

In this mode of operation, measurements can be commanded, and the numerical value of the temperature can

be read.

How to Configure:

sleep = 0

stop = 0

sltimeena = X

oneburst = 1

The stop bit will be set to 1 once the measurement is complete.

The output pin is designed to be an open drain output, which allows you to connect multiple devices in parallel

to trigger an alert. The output is driven low once the temperature crosses the operate point, and released once

it goes below the release point. The temperature operate and release points are factory set to 80 °C and 75 °C

but these values can be adjusted by setting the bit usestore to 1 and adjusting the data in registers 0xC6 and

0xC7 as will be described later. It is possible to adjust the output pin polarity so it goes high or low as

temperature increases.
