The reset output is active low and push-pull, so it drives a clean logic level without needing an external pull-up resistor. Reset timeout is a minimum of 140ms, giving the system time to stabilize before the processor starts executing code. The part is AEC-Q100 qualified and rated for the full automotive temperature range of -40°C to 125°C, making it suitable for under-hood electronics, engine control modules, and industrial equipment that sees wide thermal swings. It monitors a single voltage rail, and the 1.58V threshold is a natural fit for 1.8V nominal rails — the monitor triggers before the rail drops below the minimum operating voltage of most 1.8V logic. ## Package and footprint Housed in a 6-WFDFN package (supplier device package 6-uDFN, 1.5mm x 1.0mm), this is a small surface-mount monitor that fits tight PCB layouts. The 6-pin footprint is common across the MAX6381 family, so swapping threshold variants within the series is a direct BOM change — no layout revision needed. ## Lifecycle and sourcing The MAX6381LT16D3+ is listed as Active in production. No end-of-life notice or last-time-buy schedule is in effect.","metaTitle":"MAX6381LT16D3+ Power Supply Monitor, AEC-Q100","metaDescription":"MAX6381LT16D3+ single low-voltage power supply monitor with 1.58V threshold, active-low reset, push-pull output.
