Frequently asked questions
What is the exact reset threshold voltage of MAX6381XR25D2+?
The reset threshold is 2.5V, monitored on a single input. The output asserts active-low when the supply drops below this level.
Does MAX6381XR25D2+ have push-pull output?
Yes, the output is push-pull (totem pole), active-low. No external pull-up resistor is needed.
Is MAX6381XR25D2+ equivalent to MAX809?
Both are single-voltage supervisors with active-low push-pull output in SC-70-3, but the MAX809 family offers multiple threshold options. The MAX6381XR25D2+ is a 2.5V fixed-threshold variant; check the MAX809's threshold options for a direct pin-compatible alternative at a different voltage.
