13 The MAX34408/MAX34409 are two- and four-channel current monitors that are
15 unidirectional current sensor offers precision high-side operation with a
16 low full-scale sense voltage. The devices automatically sequence through
17 two or four channels and collect the current-sense samples and average them
19 user-programmable digital thresholds to indicate overcurrent conditions.
