DESCRIPTION  
Recirculation control  
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%.  
Regulator drift detection  
Regulator error control  
Regulator resolution 5mA  
Status monitoring  
All channels are protected against fail functions.  
They are monitored by a status output.  
Status push-pull stages  
Electrostatic discharge (ESD) protection
