The LTC

2906/LTC2907 are dual supply monitors in-

tended for systems with multiple supply voltages. The

dual supply monitors have a common reset output with

delay (200ms for the LTC2906 and adjustable using an

external capacitor for the LTC2907). These products pro-

vide a precise, space-conscious and micropower solution

for supply monitoring.

The LTC2906/LTC2907 feature a tight 1.5% threshold

accuracy over the whole operating temperature range

and glitch immunity to ensure reliable reset operation

without false triggering. The open drain RST output state

is guaranteed to be in the correct state for V1 and/or V

down to 1V.

The LTC2906/LTC2907 also feature one adjustable input

with a nominal threshold level at 0.5V, another input with

three possible input threshold levels, and three supply

tolerances for possible margining. These features provide

versatility for any kind of system requiring dual supply

monitors. Two three-state input pins program the thresh-

old and tolerance level without requiring any external

components.
