Product Summary
The LTC2901-1CGN#TR is a programmable supply monitor for systems with up to four supply voltages. One of 16 preset or adjustable voltage monitor combinations can be selected using an external resistor divider connected to the program pin. The preset voltage thresholds are accurate to 1.5% over temperature. All four voltage comparator outputs are connected to separate pins for individual supply monitoring. The applications of the LTC2901-1CGN#TR are (1)desktop and notebook computers; (2)multivoltage systems; (3)telecom equipment; (4)portable battery-powered equipment; (5)network servers.
