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. The ADM1025A has
open-drain VID inputs while the ADM1025 has on-chip 100 k
W
pull-ups on the VID inputs.
Measured values and in/out of limit status can be read out via an I2C
compatible serial System Management Bus. The device can be
controlled and configured over the same serial bus. The device also
has a programmable INT output to indicate undervoltage, overvoltage,
and overtemperature conditions.
The ADM1025/ADM1025A’s 3.0 V to 5.5 V supply voltage range,
low supply current, and I2C compatible interface make it ideal for a
wide range of applications. These include hardware monitoring and
protection applications in personal computers, electronic test
equipment, and office electronics.
