LTC2900-1IDD#PBF

LTC2900-1 is a programmable quad supply monitor with adjustable reset timer. 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. 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. The RST output is guaranteed to be in the correct state for VCC down to 1V. This device features an open-drain RST output. It is widely used in application such as desktop and notebook computers, multivoltage systems, telecom equipment, portable battery-powered equipment, network servers etc.
