Product details

4.39V threshold supervisor in a SOT-143-4

The MAX6314US44D3+T from Maxim Integrated is a simple reset/power-on reset IC that monitors a single voltage rail and asserts an active-low reset when the supply drops below 4.39V. The bidirectional output allows the device to both drive and be driven by the reset line, simplifying daisy-chain or shared-reset topologies. With a minimum reset timeout of 140ms, it holds the system in reset long enough for the supply and oscillator to stabilise after power-up. The SOT-143-4 package suits compact, surface-mount designs in industrial temperature environments (-40°C to 85°C).

Where it fits in the cycle

This part carries an Active lifecycle status and ROHS3 compliance, so there is no last-time-buy or obsolescence signal to manage. For a 5V rail supervisor in a SOT-143-4 footprint, it is a straightforward BOM line to qualify — no allocation pressure typical of more complex PMICs. The stock we see is franchised-origin excess, not phantom double-ordering inventory; the spot premium over book price is narrow, reflecting steady supply. For volume commitments, we quote against an RFQ with current availability confirmed at quote time.

Frequently asked questions

What is the reset timeout of MAX6314US44D3+T?

The reset timeout is a minimum of 140ms, ensuring the system stays in reset long enough for the power supply and oscillator to stabilise.

Is MAX6314US44D3+T a replacement for MAX6314US44D2?

The MAX6314US44D3+T and MAX6314US44D2 share the same package and pinout, but the suffix indicates a different reset timeout option. Verify the timeout required for your application before substituting — the 'D3' variant carries a 140ms minimum timeout.

What is the closest pin-compatible alternative to MAX6314US44D3+T?

Within the MAX6314 family, other suffix variants offer different reset timeout values while maintaining the same SOT-143-4 footprint and 4.39V threshold. For a different timeout, select the appropriate suffix; for a different threshold, step to the MAX6315 or MAX6316 series, which share the same pinout.
