DescripTion

The LTC

systems with multiple supply voltages. Each supply moni-

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.

The LTC1728 is functionally identical to the LTC1727

without the individual monitor outputs.

The RST output is guaranteed to be in the correct state

for V

LTC1728 may also be configured to monitor any one or

two V

requirements.

Very low (10µA typical) supply current makes the LTC1727/

LTC1728 ideal for power conscious systems.

The LTC1727 is available in an 8-lead MSOP or SO pack-

age and the LTC1728 is available in a 5-lead SOT-23

package.
