Its job is to hold a microprocessor or logic device in reset until the supply rail is stable, and to assert reset again if the rail dips below the threshold. That 2.19 V figure is the one you match against the minimum operating voltage of the downstream device — pick a threshold above the processor's brownout floor, not below it. The reset timeout is 140 ms minimum, giving the supply and oscillator time to settle before the processor starts executing code. ## Temperature grade and deployment context The package is SC-70-3 (SOT-323), a 3-lead surface-mount footprint that fits tight layouts. The supplier device package is SC-70-3, so the PCB land pattern is standard for that outline — no special footprint work needed.","metaTitle":"MAX6381XR22D3+ Power Supply Monitor, 2.19V Threshold, SC-70","metaDescription":"MAX6381XR22D3+ Power Supply Monitor from Analog Devices.
