LM75

Digital Temperature Sensor and Thermal Watchdog with

Two-Wire Interface

n Register readback capability

n Power up defaults permit stand-alone operation as

General Description

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

thermostat

digital converter, and digital over-temperature detector with

n Shutdown mode to minimize power consumption

n Up to 8 LM75s can be connected to a single bus

n UL Recognized Component

I²C^®interface. The host can query the LM75 at any time to

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.

Key Specifications

The host can program both the temperature alarm threshold

(T_OS) and the temperature at which the alarm condition goes

away (T_HYST). In addition, the host can read back the con-

tents of the LM75’s T_OSand T_HYSTregisters. Three pins (A0,

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

powers up in Comparator mode with default thresholds of

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

current and I²C interface make it ideal for a wide range of

applications. These include thermal management and pro-

tection applications in personal computers, electronic test

equipment, and office electronics.

n System Thermal Management

n Personal Computers

n Office Electronics

n Electronic Test Equipment

n SOP-8 and Mini SOP-8 (MSOP) packages save space

n I²C Bus interface

n Separate open-drain output pin operates as interrupt or

comparator/thermostat output
