What the 2.32V threshold means for your rail
The MAX6365PKA23+T is a battery backup supervisor IC that monitors a single voltage rail and asserts a reset signal when the supply drops below 2.32V. The active-low, open-drain output pulls low during a fault and floats when the rail is good — a common interface for microcontroller reset pins that need a pull-up resistor to the logic supply.
Housed in a SOT-23-8 package (supplier device package SOT-23-8), this surface-mount IC is small enough for handheld or battery-powered gear. The open-drain output means the reset signal level is set by the pull-up voltage, not the IC itself — so it works with 1.8V, 3.3V, or 5V logic as long as the pull-up resistor connects to the appropriate rail. No level shifter needed between the supervisor and the monitored processor.
Sourcing and lifecycle posture
ROHS3 compliant, so it meets the latest EU restriction requirements without a separate waiver. Tape-and-reel packaging (cut tape also available) suits automated pick-and-place assembly.
