30 µs reset timeout — fast reaction, no debounce
The reset timeout is 30 µs typical. That is short — the part releases reset 30 µs after the supply recovers above the threshold. For a microcontroller with a fast oscillator start-up, that is fine; for a system with a slow-ramping supply or a noisy rail, you may see repeated reset cycles. No external capacitor adjusts the timeout on this part — it is fixed. If the application needs a longer delay to let the oscillator stabilise, consider a supervisor with a programmable timeout or an external RC delay on the reset line.
Package and temperature range
Housed in an 8-µMAX package (the Maxim-specific name for an 8-pin MSOP, 3.00 mm width), the MAX6807UA46 is a surface-mount part rated for -40°C to 85°C ambient. That industrial temperature range covers most factory-floor, outdoor telecom, and automotive-cabin environments. The µMAX footprint is not identical to a standard MSOP-8 — verify the land pattern against the datasheet before committing the board layout.
Lifecycle and sourcing
The MAX6807UA46 carries an active lifecycle status. This variant is marked RoHS non-compliant.
