Product details

Single-channel supervisor with adjustable threshold in SOT-23-6

The open-drain or open-collector output stays low for a typical 50 µs reset timeout after the rail returns, giving the system a clean power-up sequence. The adjustable threshold means a single ordering code covers multiple rail voltages — set the trip point with an external resistor divider, which simplifies BOM consolidation across designs with different core or I/O voltages.

Industrial temperature grade and surface-mount footprint

The SOT-23-6 package (supplier device package SOT-6) is a common footprint for supervisor ICs, so layout reuse across multiple supply-rail monitors is straightforward. Surface-mount assembly keeps the pick-and-place step simple for medium-to-high-volume production.

Frequently asked questions

Does MAX6459UTB+T have an adjustable reset threshold?

Yes, the voltage threshold is adjustable/selectable. An external resistor divider sets the trip point, so one part number can monitor different rail voltages across the board.

What is the closest pin-compatible alternative to MAX6459UTB+T in this component family?

The MAX6458 is a same-function sibling in the same SOT-23-6 package family. The primary difference is the reset timeout — the MAX6459UTB+T has a typical 50 µs timeout, while the MAX6458 uses a different timeout value. Verify the timeout requirement for your application before substituting.
