Introduction
A configurable supply monitor for systems with up to 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. The preset voltage thresholds are accurate to ±1.5% over temperature. It also features adjustable inputs with a 0.5 nominal threshold. All six open-drain voltage comparator outputs are connected to separate pins for individual supply monitoring. The reset and watchdog timeout periods are adjustable using external capacitors. 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. Each status output has a weak internal pull-up and may be externally pulled up to a user defined voltage. The 52μA supply current makes it ideal for power conscious systems and it may be configured to monitor fewer than six inputs.
