Product details

Package and temperature grade — board-fit constraints

Housed in a SOT-23-8 package, this part fits tight layouts where board space is at a premium. The surface-mount footprint matches the standard SOT-23-8 land pattern; no special pad geometry required. Rated for -40°C to 85°C ambient, it covers industrial control, telecom base stations, and outdoor equipment enclosures where the internal temperature stays below 85°C.

Lifecycle and sourcing — active, no LTB pressure

Listed as Active with ROHS3 compliance.

Frequently asked questions

Can MAX6366LKA46+T monitor a 5V rail?

Yes. The 4.63V threshold is designed for 5V nominal supplies — it asserts reset when the rail drops to approximately 4.63V, which is within the typical undervoltage window for 5V logic. It monitors a single voltage input.

What is the closest pin-compatible alternative to MAX6366LKA46+T?

Within the MAX6366 family, the threshold voltage is the differentiating factor. The MAX6366LKA29+T uses a 2.93V threshold for 3.3V rails, and the MAX6366LKA31+T uses a 3.08V threshold. All share the same SOT-23-8 package, active-low push-pull output, and 150ms timeout — the only difference is the monitored voltage level. For a 5V rail, the 4.63V variant is the correct choice.

Is MAX6366LKA46+T compatible with 3.3V systems?

No. The 4.63V threshold is too high for a 3.3V rail — the reset would assert continuously. For 3.3V systems, use a threshold variant such as the MAX6366LKA29+T (2.93V) or MAX6366LKA31+T (3.08V).
