General Description
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
I
2
C 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 (T
OS
) and the hysteresis
temperature below which the alarm condition is not
valid (T
HYST
). Also, the LM75s T
OS
and T
HYST
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 T
OS
= +80癈 and T
HYST
= +75癈. The 3.0V
to 5.5V supply voltage range, low supply current, and
I
2
C interface make the LM75 ideal for many applica-
tions in thermal management and protection.
