Product details

Reset architecture and threshold fit

The MAX6834FXRD3+: That timeout window covers most processor power-up sequences without needing an external delay capacitor. The open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button, pulling to the rail voltage you choose via an external pull-up resistor.

SC-70-3 package — board-fit note

The supplier device package is SC-70-3, surface-mount only. No special thermal pad or exposed die attach — standard reflow profile for a small-outline transistor package applies.

Compliance documentation available

Analog Devices provides ROHS3 compliance certification for this part.

Frequently asked questions

What is the reset output type and polarity for MAX6834FXRD3+?

The reset output is active-low, open-drain. It requires an external pull-up resistor to the logic supply rail. The output asserts low when the monitored voltage falls below the 1.665 V threshold and remains low for at least 140 ms after the rail returns above threshold.
