Product details

Two-rail supervisor in a six-pin SOT

The MAX6449UT46L+T is a multi-voltage supervisor from Analog Devices (formerly Maxim Integrated) that monitors two supply rails — one fixed at 4.625 V and a second adjustable channel — and holds the processor in reset until both are stable. The active-low, push-pull output drives directly into the reset input of an MCU, FPGA, or SoC without an external pull-up. The 140 ms minimum reset timeout gives the main supply and crystal oscillator time to settle before the system boots. Housed in a SOT-23-6 package (supplier device package SOT-6), it is a surface-mount part rated for the -40°C to 85°C industrial temperature range. The part is ROHS3 compliant and carries an active lifecycle status — no end-of-life notice, suitable for new designs and ongoing production.

Frequently asked questions

What is the exact reset threshold of MAX6449UT46L+T?

The fixed threshold is 4.625 V for the primary channel. A second channel is adjustable via an external resistor divider.

Is MAX6449UT46L+T active low or active high reset?

The reset output is active low — it pulls low when the monitored voltage falls below the threshold and releases after the 140 ms timeout.

Is MAX6449UT46L+T obsolete or end-of-life?

No — the part is listed as Active in production status. There is no end-of-life notice, and it remains suitable for new designs and ongoing production.
