LTC2932IF#PBF

LTC2932 is a configurable supply monitor for systems with upto six supply voltages. One of 16 preset or adjustable voltage monitor combinations can be selected using an external resistive divider connected to the mode select pin. It also features adjustable inputs with a 0.5V nominal threshold. All six open-drain voltage comparator outputs are connected to separate pins for individual supply monitoring. The reset timeout period is adjustable using an external capacitor. The RST output is guaranteed to be in the correct state for VCC down to 1V and may be disabled during supply margin testing. Each status output has a weak internal pull-up and may be externally pulled upto an external voltage. It is used in application such as desktop and notebook computers, multivoltage systems, telecom equipment, portable battery-powered equipment, network servers, automotive etc.
