Supervisor IC for single-voltage monitoring
The MAX6467US22D3+T is a simple reset/power-on reset IC from Analog Devices, monitoring a single voltage rail with a 2.188V threshold and asserting an active-low, open-drain reset output when the supply dips below that level. The reset timeout is a minimum of 150ms, giving the downstream processor time to stabilize after the supply returns above the threshold.
SOT-143-4 footprint and mounting
Housed in the SOT-143-4 package (also known as TO-253-4, TO-253AA), this is a surface-mount device with four leads — the same footprint used by many single-channel supervisors from Maxim/Analog Devices. Supplied in Tape & Reel (TR) or Cut Tape (CT) options, it integrates directly into standard pick-and-place assembly without a package change.
It is cataloged under Microcontrollers & Processors (MCU / MPU / DSP) but functions as a supervisory companion — a reset generator for the processor core.
