Network Servers and Personal Computers Microprocessor-Based Office Equipment Test Equipment and Measuring Instruments Remote Thermal Diode Monitor with Linear Fan Control ADM1028 GENERAL DESCRIPTION
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. An automatic hardware temperature trip point is provided and the fan will be driven to full speed if it is exceeded.
