LTC2908IDDB-B1#TRMPBF

LTC2908 is a six input supply monitor for systems requiring a precise and compact monitoring solution for multiple supply voltages. The inputs can be shorted together for monitoring systems with fewer than six supply voltages, and the open drain RST output of two or more devices can be wired-OR together for monitoring systems with more than six supply voltages. The common reset output remains low until all six inputs have been in compliance for 200ms. It features a tight 1.5% threshold accuracy over the entire 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 as long as V1 and/or V2 is 0.5V or greater. It is widely used in application such as network servers, wireless base stations, optical networking systems, multivoltage systems, desktop and notebook computers etc.

• Active low open-drain RST output
• Internal supply voltage is 0.5V to 6V
• Operating temperature is -40°C to 85°C
• Package style is 8-lead plastic DFN
