The LTC2930 is 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. The LTC2930 also features adjustable inputs with a 0.5V nominal threshold.
The reset timeout period is adjustable using an external capacitor. A reset event may be generated with a manual reset button on the manual reset input. 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 and may be externally pulled up to an external voltage.
The 52μA supply current makes the LTC2930 ideal for power conscious systems and it may be configured to monitor fewer than six inputs.
