Hardware Monitor ASIC

ADM1025/ADM1025A*

FEATURES

PRODUCT DESCRIPTION

Up to Eight Measurement Channels

Five Inputs to Measure Supply Voltages

V_CCMonitored Internally

External Temperature Measurement with Remote Diode

On-Chip Temperature Sensor

The ADM1025/ADM1025A is 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 moni-

tored. The ADM1025A has open-drain VID inputs while the

ADM1025 has on-chip 100 kΩ pull-ups on the VID inputs.

Five Digital Inputs for VID Bits

Integrated 100 k⍀ Pull-Ups on VID Pins (ADM1025 Only)

LDCM Support

I²C^®-Compatible System Management Bus (SMBus)

Programmable RESET Output Pin

Programmable INT Output Pin

Conﬁgurable Offset for Internal/External Channel

Shutdown Mode to Minimize Power Consumption

Limit Comparison of all Monitored Values

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 under-

voltage, overvoltage and over-temperature 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.
