Description

The ADM1025/ADM1025A 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 on-chip temperature sensor allows ambient temperature to be monitored. The ADM1025A has open-drain VID inputs while the
ADM1025 has on-chip 100 kΩ pull-ups on the VID inputs.

The ADM1025/ADM1025A's 3.0 V to 5.5 V supply voltage range, low supply current, and I2C-compatible interface make ADM1025/ADM1025A  ideal for a wide range of applications. These include hardware monitoring and protection applications in personal computers, electronic test equipment, and office electronics.
