L9347 General Description

The L9347 is an integrated quad low-side power switch to drive inductive loads like valves used in ABS systems. Two of the four channels are current regulators with current range from 250mA to 2.25A and an accuracy of 10%.

All channels are protected against fail functions. They are monitored by a status output.
