LM75引腳圖如下：
The LM75 temperature sensor includes a delta-sigma
analog-to-digital converter, and a digital overtempera-
ture detector. The host can query the LM75 through its
I2C interface to read temperature at any time. The
open-drain overtemperature output (OS) sinks current
when the programmable temperature limit is exceeded.
The OS output operates in either of two modes, com-
parator or interrupt. The host controls the temperature
at which the alarm is asserted (TOS) and the hysteresis
temperature below which the alarm condition is not
valid (THYST). Also, the LM75’s TOS and THYST regis-
ters can be read by the host. The address of the LM75
is set with three pins to allow multiple devices to work
on the same bus. Power-up is in comparator mode, with
defaults of TOS = +80°C and THYST = +75°C. The 3.0V
to 5.5V supply voltage range, low supply current, and
I2C interface make the LM75 ideal for many applica-
tions in thermal management and protection.
