4.63V threshold supervisor for automotive power rails
The MAX6324AUT46+ is a single-channel power supply monitor that asserts a reset signal when the monitored voltage drops below 4.63V, with a guaranteed minimum reset timeout of 100ms. The reset output is active-low, open-drain — it pulls low on a fault and releases after the timeout period once the supply recovers above the threshold. This suits interfaces where multiple supervisors share a common reset bus.
Automotive temperature grade and package fit
An ECU or sensor module that sees 105°C on a summer grade still has margin to the upper limit. Housed in a SOT-23-6 package, the footprint is standard for a 6-pin supervisor — the same land pattern serves multiple threshold variants in the MAX6324 family, so a single PCB layout covers a range of voltage rails.
