Product details

AEC-Q100 qualification and temperature range

Rated for -40°C to 125°C, the MAX6381LT44D3+ is AEC-Q100 qualified. It has passed stress tests for under-hood and chassis-domain electronics.

Package and footprint

Housed in a 6-WFDFN (6-uDFN 1.5x1 mm) surface-mount package, the MAX6381LT44D3+ occupies minimal board area. The supplier device package is 6-uDFN (1.5x1). The small footprint suits space-constrained designs — sensor modules, compact ECU boards, or multi-rail PMICs where each supervisor is placed close to its monitored rail. No through-hole option; this is a surface-mount-only part.

Sourcing and lifecycle

Listed as Active on the lifecycle record, the MAX6381LT44D3+ is current-production and RoHS3 compliant. There is no NRND or last-time-buy flag.

Frequently asked questions

Is MAX6381LT44D3+ automotive qualified?

Yes, it is AEC-Q100 qualified, rated for the -40°C to 125°C operating temperature range, making it suitable for automotive under-hood and chassis-domain applications.

What is the difference between MAX6381LT44D3+ and MAX6381LT44D3+T?

The suffix +T typically indicates tape-and-reel packaging. The MAX6381LT44D3+ is listed with Bulk packaging. Electrically and functionally they are identical — same 4.38V threshold, same 140ms minimum reset timeout, same AEC-Q100 qualification. The choice is a packaging preference for your assembly line.

Is MAX6381LT44D3+ obsolete?

No. The lifecycle record shows an Active status. It is current-production and not subject to a last-time-buy or end-of-life notice.
