The LTC2932 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 digitally conﬁgurable to 5%, 7.5%, 10%, or 12.5% below the nominal operating voltage. The LTC2932 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 V_CC 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 up to an external voltage.

The 52μA supply current makes the LTC2932 ideal for power conscious systems and the part may be conﬁgured to monitor less than six inputs.
