Linear Technology LTC1727/LTC1728 Datasheet
The LTC1727/LTC1728 are micropower precision triple‑supply monitors designed for systems with multiple supply voltages. Each supply input has an open‑drain monitor output, and a common reset output stays low until all supplies are within spec for 200 ms. The devices offer 1.5 % threshold accuracy over temperature, very low 10 mA typical supply current, and built‑in glitch immunity.
The datasheet provides full electrical characteristics, pin descriptions, and package options (8‑lead MSOP/SO for LTC1727 and 5‑lead SOT‑23 for LTC1728). Typical performance graphs, block diagrams, and application examples illustrate power‑up, power‑down, and override functions for 3.3 V, 5 V, 2.5 V, and 1.8 V monitoring configurations.

Questions answered in these manuals
What is the typical supply current of the LTC1727/LTC1728?
The devices draw about 10 mA typical supply current.
How long does the reset output stay low after power‑up?
The reset output remains low for approximately 200 ms after all supplies become valid.
What type of output does the RST pin provide?
The RST pin is an active‑low, open‑drain logic output with a weak pull‑up to Vec3.
How many supply inputs does the LTC1727 monitor simultaneously?
It monitors three inputs simultaneously (5 V, 3.3 V, and an adjustable voltage).
