TYPICAL APPLICATION
DESCRIPTION
Precision Triple Supply
Monitor with Power-Fail
Comparator
The LTC2911 is a low power, high accuracy triple supply
monitor with a power-fail comparator. Reset timeout may
beselectedwithanexternalcapacitororsettoaninternally
generated 200ms.
The V1 pin monitors a 3.3V supply. The V2 pin monitors a
5V, 2.5V, 1.8V, 1.2V or adjustable supply. A third adjustable
input has a nominal 0.5V threshold allowing a resistive
divider to configure its threshold. All three comparators
feature a tight 1.5% threshold accuracy over the entire
operating temperature range while a glitch filter ensures
reliable reset operation.
A spare comparator can be configured to provide early
warningofalowvoltagecondition.ItcausesthePFOoutput
topulllowwhenthevoltageofthePFIinputfallsbelow0.5V,
allowing the power-fail threshold to be configured with
a resistive divider. A latch feature on the TMR pin allows
the RST output to be latched to prevent system resets,
simplifying margin testing.
