DESCRIPTION
The L9352 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.
