LTC2907CTS8#TRMPBF

LTC2907 is a dual supply monitor intended for systems with multiple supply voltages. This device 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 state is guaranteed to be in the correct state for V1 and/or VCC down to 1V. It also feature one adjustable input with a nominal threshold level at 0.5V, another input with three possible input threshold levels, and three supply tolerances for possible margining. It features provide versatility for any kind of system requiring dual supply monitors. Two three-state input pins program the threshold and tolerance level without requiring any external components. It is used in application such as desktop and notebook computers, handheld devices, network servers, core, I/O monitor etc.
