DESCRIPTIO

The LTC

systems with multiple supply voltages. The reset output

remains low until all three supplies have been in compli-

ance for 200ms. Tight 1.5% accuracy specifications and

glitch immunity ensure reliable reset operation without

false triggering.

The RST output is guaranteed to be in the correct state for

configured to monitor any one or two V

of three, depending on system requirements.

Very low (10 A typical) supply current makes the LTC1985

ideal for power conscious systems.

The LTC1985 is available in a 5-lead SOT-23 package.
