L9352B：four channel valve driver
The L9352B 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 0 mA to 2.25 A.
All channels are protected against fail functions. They are monitored by a status output.
