FEATURES

G E NE R AL D E S C R IP T IO N

T he ADM1028 is a low-cost temperature monitor and fan

controller for microprocessor-based systems. T he tem-

perature of a remote sensor diode may be measured, al-

lowing monitoring of processor temperature in single

processor systems. An on-chip temp sensor monitors

ambient system temperature.

Interrupt and Overtem perature Outputs

Fault Tolerant Fan Control With Auto Hardw are Trip Point

Rem ote Reset and Pow er Dow n Functions

LDCM Support

Measured values can be read out via the System Manage-

ment Bus, and values for limit comparisons can be pro-

grammed in over the same serial bus.

System Managem ent Bus (SMBus) Com m unications

Standby Mode to Minim ize Pow er Consum ption

Lim it Com parison of all Monitored Values

T he ADM1028 also contains a DAC for fan speed con-

trol. An automatic hardware temperature trip point is pro-

vided and the fan will be driven to full speed if it is

exceeded.

APPLICATIONS

Netw ork Servers and Personal Com puters

Microprocessor-Based Office Equipm ent

Test Equipm ent and Measuring Instrum ents

Finally, the chip has remote reset and power down

functionality, allowing it to be remotely shutdown via the

SM Bu s.

T he ADM1028’s 3.0V to 5.5V supply voltage range, low

supply current, and SMBus make it ideal for a wide range

of applications. T hese include hardware monitoring

applications in PCs, electronic test equipment, and office

electronics.
