The LTC
1727 is a triple supply monitor intended for
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
VCC5/VCC25/VCC18 or VCC3 down to 1V. The LTC1727/
LTC1728 may also be configured to monitor any one or
two VCC inputs instead of three, depending on system
requirements.

The LTC1727 is available in an 8-lead MSOP or SO
package and the LTC1728 is available in a 5-lead SOT-23
package.
