Product details

Dual-channel temperature monitor with integrated fan control

It monitors its own die temperature and an external diode-connected transistor, reporting readings over an SMBus interface.

What the ±4°C accuracy means for your BOM

That is wide enough for fan-speed ramping and overtemperature alarms.

Package and ordering options

Supplied in a 16-pin QSOP (3.90 mm body width), surface-mount only. Cut Tape (CT) is also listed for prototype or small-batch builds.

ROHS3 compliant, no exemptions expiring.

Frequently asked questions

What is the accuracy of the MAX6615AEE+T temperature monitor?

±4°C maximum over the full -40°C to 125°C operating range. This is the total uncalibrated error — no external trimming required.

Does MAX6615AEE+T support both internal and external temperature sensors?

Yes. It monitors its own internal die temperature and an external diode-connected transistor (typically a 2N3906 or similar). The SMBus interface returns both readings.

What is the difference between MAX6615AEE+T and MAX6615AEE?

The +T suffix indicates Tape & Reel packaging (2500 pieces per reel). The non-T suffix is typically supplied in tubes. The die, function, and specifications are identical.
