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.

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.
