Product details

Active and available — no EOL concern here

The MAX6806UA46: The reset output is Active Low with a Push-Pull, Totem Pole stage — it drives the reset line directly without an external pull-up resistor, which simplifies the board layout around the supervisor.

Specs that define the fit

Monitors a single voltage rail at 4.6 V threshold — this is the undervoltage trip point for a 5 V supply. Housed in the 8-µMAX package (3.00 mm × 3.00 mm MSOP footprint), it shares the same 0.65 mm pitch and body size as the standard 8-MSOP/TSSOP — the layout is compatible with both footprint variants listed in the datasheet.

RoHS note for compliance tracking

Marked RoHS non-compliant — the part uses lead-bearing solder terminations. For a BOM that requires full RoHS exemption compliance (e.g., lead in high-reliability solder joints per exemption 7(c)-I), this is acceptable; for a general RoHS-10 compliant build, an alternative part with lead-free plating is needed.

Frequently asked questions

What is the exact reset output type of MAX6806UA46?

The reset output is active-low, push-pull (totem pole). No external pull-up resistor is required.

Can I use MAX6806UA46 as a replacement for MAX6805UA46?

The MAX6805 and MAX6806 families share the same pinout and package options, but the threshold voltage differs. The MAX6806UA46 has a 4.6V threshold; the MAX6805UA46 has a different threshold. Verify the voltage threshold matches your rail before substituting. Both are active-low push-pull outputs with a 30 µs timeout.
