Two-rail watchdog in a SOT-23-6
The Maxim Integrated MAX6715UTVDD3 is a multi-voltage supervisor that monitors two independent supply rails. It asserts a reset output when either monitored voltage drops below its threshold, then holds reset for a minimum of 140ms after both rails recover. The active-low, open-drain output lets you wire-OR the reset signal with other supervisors or a manual reset button.
Package and rework considerations
SOT-23-6 is a small-outline transistor package. Keep traces short to the monitored rails to avoid noise injection.
Lifecycle and sourcing
The MAX6715UTVDD3 is listed as Active in production. RoHS non-compliant — verify if your BOM accepts lead-bearing solder.
