A2557 Product details

Description

AND APPLICATION The A2557 low-current quad power drivers provide the same protected output driver function as (and are pin compatible with) the UDx2543/49/59 devices, combined with a fault diagnostic scheme similar to the UDx2547, plus an automatic low-current Sleep-Mode function.These devices monitor their outputs for fault (open or shorted) conditions.For each channel the input and output levels are compared.If these are different from the expected levels then a fault condition is flagged b

Features
