What this chip is and where it lands on the board
The Maxim Integrated DS28E83Q+T is a DeepCover® authentication chip — a dedicated security IC that validates the identity of a consumable, accessory, or module before the system enables its full function. It is listed for medical applications, which means the part carries the compliance overhead (traceability, anti-tamper, key storage) that a hospital-grade device demands. The 6-TDFN package with exposed pad (3x3 mm footprint) is a small outline that fits on a sensor pod or disposable cartridge PCB without eating up real estate.
Package and footprint — what the 6-TDFN means for assembly
Surface-mount package with exposed pad. The supplier device package is 6-TDFN (3x3 mm). The exposed pad needs a thermal land on the PCB — not just for heat sinking but for a solid ground return.
Lifecycle and sourcing reality
Status is Active per the manufacturer — no NRND flag, no last-time-buy notice. ROHS3 compliant, so it passes the EU material declarations without an exemption letter.
