ADM1025/ADM1025A

Preliminary Technical Data

FEATURES

Up to 8 measurement channels

5 inputs to measure supply voltages

PRODUCT DESCRIPTION

The ADM1025/ADM1025A¹is a complete system hardware

monitor for microprocessor-based systems, providing measure-

ment 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 V_CC. 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.

_CCmonitored internally

External temperature measurement with remote diode

On-chip temperature sensor

5 digital inputs for VID bits

Integrated 100 kΩ pull-ups on VID pins (ADM1025 only)

LDCM support

I²C® compatible system management bus (SMBus)

Programmable

Configurable offset for internal/external channel

Shutdown mode to minimize power consumption

Limit comparison of all monitored values

RST

INT

output pin

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.

APPLICATIONS

Network servers and personal computers

Microprocessor-based office equipment

Test equipment and measuring instruments

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.
