LTC1326CS8

概述
The LTC1326CS8 are triple supply monitors intended for systems with multiple supply voltages. They provide micropower operation, small size and high accuracy supply monitoring.
Tight 0.75% threshold accuracy and glitch immunity ensure reliable reset operation without false triggering. The 20μA typical supply current makes the LTC1326CS8 ideal for power-conscious systems.
The RST output is guaranteed to be in the correct state for VCC3, VCC5 or VCC25 down to 1V. The LTC1326CS8 can be configured to monitor one, two or three inputs, depending on system requirements.
A manual push-button reset input provides the ability to generate a very narrow “soft” reset pulse (100μs typ) or a 200ms reset pulse equivalent to a power-on reset. Both SRST and RST outputs are open-drain and can be OR-tied with other reset sources.
