GENERAL DESCRIPTION
The ADM1028 is a low-cost temperature monitor and fan
controller for microprocessor-based systems. The temperature
of a remote sensor diode may be measured, allowing monitoring
of processor temperature in single processor systems. An on-chip
temperature sensor monitors ambient system temperature.
Measured values can be read out via the System Management
Bus, and values for limit comparisons can be programmed in
over the same serial bus.
The ADM1028 also contains a DAC for fan speed control. An
automatic hardware temperature trip point is provided and the fan
will be driven to full speed if it is exceeded. A Ramp Rate Register
is provided to control the rate with which fan speed is increased or
decreased. This is to eliminate sudden changes in fan speed,
thereby reducing fan acoustics and prolonging the fan’s life.
Finally, the chip has remote reset and power-down functionality,
allowing it to be remotely shut down via the SMBus.
The ADM1028’s 3.0 V to 5.5 V supply voltage range, low
supply current, and SMBus make it ideal for a wide range of
applications. These include hardware monitoring applications
in PCs, electronic test equipment, and office electronics.
