Product details

Fan control and temperature monitor with SMBus

The ADM1028ARQ from Analog Devices combines fan control and temperature monitoring in a single IC, using an internal sensor and support for an external thermal diode.

0°C to 100°C — commercial temperature grade

Both the sensing temperature and the operating temperature range are specified from 0°C to 100°C. That covers most indoor equipment, rack-mount gear, and well-ventilated enclosures, but it does not extend to automotive under-hood, outdoor base stations, or downhole tools. For those environments, a part with an extended or industrial temperature range would be needed.

Package options: 16-SSOP and 16-QSOP

Either way, the PCB land pattern is a standard 0.025" pitch SSOP/QSOP footprint.

Frequently asked questions

Does ADM1028ARQ support SMBus communication?

Yes, the output type is SMBus. The part communicates over the system management bus, which is standard in server and telecom platforms for reporting temperature and fan speed data.

Is ADM1028ARQ a direct replacement for ADM1028?

The ADM1028ARQ is functionally identical to the ADM1028 base part — same fan control, same temperature monitor, same SMBus interface. The suffix "ARQ" indicates the 16-SSOP package variant. It is a drop-in replacement for the ADM1028 in that package.
