Product details

What the ADM1027ARQZ-REEL does on your board

The Analog Devices ADM1027ARQZ-REEL is a dBCool remote thermal controller that combines fan control and temperature monitoring. Internally it integrates an ADC, comparator, fan speed counter, multiplexer, and register bank — so it can read one or two temperature diodes (internal and external sensor paths), compare against programmed limits, and drive a fan output accordingly over SMBus. The ±1°C temperature accuracy is sufficient for closed-loop fan speed regulation in most server, telecom, and industrial equipment where keeping the airflow matched to the thermal load saves acoustic noise and fan wear.

Temperature range and where it fits

Rated for 0°C to 105°C ambient operation, with the external sensor path covering the same span.

Lifecycle and sourcing posture

The ADM1027ARQZ-REEL carries an Active lifecycle status and is ROHS3 compliant.

Frequently asked questions

What is the exact functionality of ADM1027ARQZ-REEL?

It is a dBCool remote thermal controller that performs fan control and temperature monitoring. It integrates an ADC, comparator, fan speed counter, multiplexer, and register bank to read internal and external temperature sensors, compare against limits, and control a fan output via SMBus.

Is ADM1027ARQZ-REEL compatible with SMBus?

Yes, the output type is SMBus, so it interfaces directly with system management buses on host controllers.

What are the equivalent parts for ADM1027ARQZ-REEL?

Functional equivalents within the same dBCool series include ADM1027ARQ, ADM1027ARQ-REEL7, and ADM1027ARQ-REEL — all share the same ±1°C accuracy, internal/external sensor support, SMBus output, and 0°C to 105°C range. The main difference is the packaging form (Bulk vs. tape-and-reel variants).
