LTC2911

Precision Triple Supply

Monitor with Power-Fail

Comparator

FEATURES

DESCRIPTION

The LTC^®2911 is a low power, high accuracy triple supply

monitor with a power-fail comparator. Reset timeout may

beselectedwithanexternalcapacitororsettoaninternally

generated 200ms.

Ultralow Voltage Reset: V = 0.5V Guaranteed

Monitors Three Inputs Simultaneously:

3.3V, 5V, ADJ (LTC2911-1)

3.3V, 2.5V, ADJ (LTC2911-2)

3.3V, 1.8V, ADJ (LTC2911-3)

3.3V, 1.2V, ADJ (LTC2911-4)

3.3V, ADJ, ADJ (LTC2911-5)

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.
