Complete Thermal System

Management Controller

The ADM1026 is a complete system hardware monitor for

microprocessor−based systems, providing measurement and limit

comparison of various system parameters. The ADM1026 has up to 19

analog measurement channels. Fifteen analog voltage inputs are

provided, five of which are dedicated to monitoring +3.3 V, +5.0 V,

and 12 V power supplies, and the processor core voltage. The

ADM1026 can monitor two other power supply voltages by

measuring its own V and the main system supply. One input (two

pins) is dedicated to a remote temperature−sensing diode. Two

additional pins can be configured as general−purpose analog inputs to

measure 0 V to 2.5 V, or as a second temperature sensing input. The

eight remaining inputs are general−purpose analog inputs with a range

of 0 V to 2.5 V or 0 V to 3.0 V. The ADM1026 also has an on−chip

temperature sensor.

LQFP−48

CASE 932

The ADM1026 has eight pins that can be configured for fan speed

measurement or as general−purpose logic I/O pins. Another eight pins are

dedicated to general−purpose logic I/O. An additional pin can be

configured as a general−purpose I/O or as the bidirectional THERM pin.

Measured values can be read out via a 2−wire serial system

management bus, and values for limit comparisons can be

programmed over the same serial bus. The high speed, successive

approximation ADC allows frequent sampling of all analog channels

to ensure a fast interrupt response to any out−of−limit measurement.
