ADM1025, ADM1025A Product Preview Low Cost PC Hardware Monitor ASIC The ADM1025/ADM1025A1 is a complete system hardware monitor for microprocessor-based systems, providing measurement and limit comparison of various system parameters. Five voltage measurement inputs are provided for monitoring 2.5 V, 3.3 V, 5 V, and 12 V power supplies and the processor core voltage. The ADM1025/ADM1025A can monitor a sixth power supply voltage by measuring its own VCC. One input (two pins) is dedicated to a remote temperature-sensing diode, and an onchip temperature sensor allows ambient temperature to be monitored. Measured values and in/out of limit status can be read out via an I2C compatible serial System Management Bus.
