LOW-VOLTAGE 2-WIRE DIGITAL TEMPERATURE SENSOR

WITH THERMAL ALARM

PRODUCT SPECIFICATION

Fully Released Specification

Product Description

Pin Configuration

The aSC7511 is a high-precision CMOS temperature

sensor with SMBus compatible serial digital interface,

intended for use in PC thermal management applications.

The aSC7511 can measure temperature of a remote

thermal diode to an accuracy of ±1°C. Internal temperature

can be measured to ±3°C.

SOP-8 and MSOP-8

SCL

SDA

V_DD

D+

D-

Communication of configuration, temperature and alarm

status takes place over the PC standard System

Management Bus (SMBus).

ALERT /

The aSC7511 features thermal alarm functions with a user-

THERM2

programmable trip and turn-off temperatures. The THERM

output comparator can be set to control a fan while

GND

THERM

ALERT signals that the remote or local temperature is

outside of a range of temperatures. ALERT pin may be

optionally configured as

a second THERM output,

THERM2 , controlling a second fan.

The aSC7511 is available in SOP-8 and MSOP-8 surface

mount packages.
