Product details

Single-rail watchdog for 3.3V processor cores

The MAX16020PTES+T is a single-channel voltage supervisor that asserts an active-low reset when the monitored rail drops below 2.946V. That threshold is trimmed for a 3.0V or 3.3V supply — the typical margin before a processor's brown-out reset triggers. Reset stays low for a minimum of 145ms after the supply recovers, which covers the power-up settling time for most MCUs and SoCs before they release the reset pin. The open-drain output lets you wire-OR this supervisor with other reset sources (manual pushbutton, second supervisor) on the same pull-up line without contention.

Industrial temp and small-footprint package

The 16-TQFN package (4x4mm) with exposed pad pulls heat into the PCB ground plane. Surface-mount assembly on standard reflow profiles; the exposed pad requires a solder paste stencil aperture that covers 50-70% of the pad area to avoid voiding.

Frequently asked questions

What supply rail does the MAX16020PTES+T monitor?

It monitors a single voltage rail with a threshold of 2.946V, designed for 3.0V or 3.3V processor supplies. The reset asserts when the rail falls below this threshold and releases after a 145ms timeout.

Can the reset output be shared with other supervisor ICs?

Yes, the open-drain output allows multiple supervisors to share a common pull-up resistor. This is useful when combining a power-on reset with a watchdog timer or manual reset button on the same line.
