Description

General part information

LTC2900 Series

The LTC2900 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 accurateto ±1.5% over temperature.The reset delay time is adjustable using an external capacitor and the manual reset input may be used with a momentary switch to issue reset pulses with programmed duration. Tight voltage threshold accuracy and glitch immunity ensure reliable reset operation without false triggering. TheRSToutput is guaranteed to be in the correct state for VCCdown to 1V. The LTC2900-1 features an open-drainRSToutput, while the LTC2900-2 has a push-pullRSToutput.The 43µA supply current makes the LTC2900 ideal for power conscious systems and it may be configured to monitor less than four inputs. The parts are available in the 10-lead MSOP and the 10-lead 3mm × 3mm DFN packages.ApplicationsDesktop and Notebook ComputersMultivoltage SystemsTelecom EquipmentPortable Battery-Powered EquipmentNetwork Servers
