Product Descriptions

The LTC?2904/LTC2905 are dual supply monitors intended for systems with two supply voltages. The dual supply monitors have a common reset output with delay (200ms for the LTC2904 and adjustable using an external capacitor for the LTC2905). 

This product provides a precise, space-conscious and micropower solution for supply monitoring.

The LTC2904/LTC2905 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 is guaranteed to be in the correct 

state for inputs down to 1V. 

The LTC2904/LTC2905 also feature three programming input pins, which program the threshold and tolerance level without requiring any external components. These three programming pins provide a total of 27 different voltage level and tolerance 

combinations, eliminating the need to have different parts for development and implementation of different systems with different voltage levels requiring monitoring function.
