LM75

Digital Temperature Sensor and Thermal Watchdog with

Two-Wire Interface

General Description

The LM75 is a temperature sensor, Delta-Sigma analog-to-

digital converter, and digital over-temperature detector with

read temperature. The open-drain Overtemperature Shut-

down (O.S.) output becomes active when the temperature

exceeds a programmable limit. This pin can operate in either

“Comparator” or “Interrupt” mode.

The host can program both the temperature alarm threshold

away (T

tents of the LM75’s T

A1, A2) are available for address selection. The sensor

powers up in Comparator mode with default thresholds of

80˚C T

The LM75’s 3.0V to 5.5V supply voltage range, low supply

current and I

applications. These include thermal management and pro-

tection applications in personal computers, electronic test

equipment, and office electronics.
