MAX34406

Quad Current-Sense Amplifier

with Overcurrent Threshold Comparators

General Description

Features

The MAX34406 is a quad, high-side, unidirectional, cur-

rent-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.

S Four Precision Current-Sense Amplifiers

S Fixed Gains of 25V/V, 50V/V, 100V/V, and 200V/V

S Less Than ±±00ꢀV of ꢁnput ꢂffset

S Less Than ±0ꢃ±6 of Gain ꢄrror ꢅT/F/ꢆH or ±0ꢃꢇ6 of

Gain ꢄrror ꢅWH

S Wide 2ꢃ0V to 2ꢇV Common Mode Range

S Analog Voltage ꢂutputs for ꢄach Amplifier

S ꢁndependent ꢂvercurrent Comparators with Fixed
