Product Details

The MAX34406 is a quad, high-side, unidirectional, current-sense amplifier that offers precision accuracy. It provides analog outputs for each of the four amplifiers that can be routed to an external ADC, and contains four overcurrent comparators with a fixed 1.0V threshold. All four comparators are logically ORed, and the result can be delayed/filtered with an external capacitor before it is fed to a latched common shutdown open-drain output pin.
