Product details

Supply rail and thermal considerations

The MAX8521ETP+: The 3V to 5.5V supply range means this part can run from a single 3.3V or 5V logic rail, simplifying the power tree. The exposed pad on the 20-TQFN package must be soldered to a PCB copper plane for adequate heat sinking — without it, the part may thermally limit under sustained TEC drive. The industrial temperature rating covers most lab, telecom, and instrumentation environments, but not under-hood automotive or downhole applications.

Lifecycle and sourcing

The MAX8521ETP+ is listed as Active with ROHS3 compliance. No obsolescence notice or last-time-buy window is in effect. For current pricing and stock availability, this part is sourced and quoted to order against an RFQ through independent distribution — confirm lead time and quantity at quote time.

Frequently asked questions

Is MAX8521ETP+ active or obsolete?

The MAX8521ETP+ is Active and ROHS3 compliant. No end-of-life notice is in effect, so it remains suitable for new designs and production builds.

What is the recommended replacement or equivalent for MAX8521ETP+?

No official replacement or pin-compatible equivalent is listed in the available documentation. For a cross-reference, the MAX8521EUP+ is a variant in a different package (TSSOP vs TQFN) — verify pin compatibility and thermal performance before substituting.

Does MAX8521ETP+ require external MOSFETs for TEC driving?

Yes, the MAX8521ETP+ is a TEC driver controller that requires external N-channel and P-channel MOSFETs to drive the TEC load. It does not integrate the power FETs on-chip.
