Product details

What this part is and where it fits

The Maxim Integrated DS28EL22Q+T is a DeepCover® authentication chip — a dedicated security IC designed to validate the identity of peripherals, accessories, or consumables in a system. It handles cryptographic challenge-response handshakes without loading the host microcontroller, making it a drop-in block for anti-cloning and tamper-detection circuits. The 6-TDFN package (3x3 mm) with exposed pad keeps the board footprint small, and the pad helps pull heat out if the part is running continuous authentication cycles.

Lifecycle and sourcing posture

The DS28EL22Q+T carries an Active lifecycle status from the manufacturer, with ROHS3 compliance. No end-of-life notice or last-time-buy window is in effect. For BOM planning, this part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.

Frequently asked questions

What is DS28EL22Q+T used for?

It is an authentication chip for verifying the identity of accessories, batteries, or consumables in a system, preventing unauthorized clones or tampering.

What is the difference between DS28EL22Q+T and DS28EL22?

The DS28EL22Q+T is the tape-and-reel packaged variant of the base DS28EL22 die. The electrical function and footprint are identical; the suffix indicates reel packaging for automated assembly.
