Fault Reporting

RESETx/RESETx asserts when SENSEx falls outside of the over-voltage or under-voltage threshold window.
RESETx/RESETx stays asserted for the reset timeout period after SENSEx fall back within the window threshold. Active-low, open-drain reset output, requires an external pullup resistor. For TPS37044, RESETx/RESETx asserts when either SENSEx or SENSEx fall outside of the window threshold. The pin can be left floating if it is unused.
