Product details

Programmable over-temperature monitor for board-level thermal protection

The AD22105ARZ-REEL7 is a single-chip thermostat from Analog Devices that asserts an Active High open-collector output when the die temperature exceeds a user-set trip point. The trip threshold is programmed with an external resistor, giving the board designer a single BOM line to cover multiple thermal trip levels across different PCB zones. The output sinks up to 10 mA — enough to drive a logic input, an LED indicator, or a small relay coil through a buffer. Quiescent current is 100 µA typical, negligible in a system that already draws tens of milliamps.

Package variant and lifecycle status

Surface-mount assembly in an 8-lead SOIC footprint; the reel quantity suits automated pick-and-place lines.

Frequently asked questions

Will AD22105ARZ-REEL7 drop into a board that was specified around AD22105ARZ without rewiring?

Yes — the AD22105ARZ-REEL7 is electrically and mechanically identical to the tube-shipped AD22105ARZ. The only difference is the shipping media (tape-and-reel vs tube), so the same PCB footprint and BOM position accept either order code.

What is the output type and what does it drive?

The output is Active High, open-collector, rated for 10 mA sink current. It pulls low on an over-temperature condition and can drive a logic gate input, an LED, or a small-signal relay through a transistor buffer.
