The LTC

1326/LTC1326-2.5 are triple supply monitors

intended for systems with multiple supply voltages. They

provide micropower operation, small size and high accu-

racy supply monitoring.

Tight 0.75% threshold accuracy and glitch immunity

ensure reliable reset operation without false triggering.

The 20µA typical supply current makes the LTC1326/

LTC1326-2.5 ideal for power-conscious systems.

The RST output is guaranteed to be in the correct state for

CC3

, V

CC5

or V

CC25

down to 1V. The LTC1326/LTC1326-2.5

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.
