FeaTures

DescripTion

The LTC^®1727 is a triple supply monitor intended for

systemswithmultiplesupplyvoltages. Eachsupplymoni-

tor has its own open-drain output for individual supply

monitoring. A common open-drain reset output remains

low until all three supplies have been in compliance for

200ms. Tight 1.5% accuracy speciﬁcations and glitch

immunity ensure reliable reset operation without false

triggering.

LTC1727-5: 5V, 3.3V and ADJ

LTC1727-2.5: 2.5V, 3.3V and ADJ

LTC1728-5: 5V, 3.3V and ADJ

LTC1728-2.5: 2.5V, 3.3V and ADJ

LTC1728-1.8: 3V, 1.8V and ADJ
