FEATURES
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 20
μ
A 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
V

,

or V

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 (100
μ
s 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.
