Quad intelligent power low side switch  
■ Four low-side output driver with protection  
diagnostics designed as a conventional switch  
– 2 channels with 5 A output current  
capability and r = 0.2 Ω typ.

– 2 channels with 3 A output current  
capability and r = 0.3 Ω typ.

■ Integrated 60 V Zener diodes output clamping  
PowerSO-20  
structure  
■ Output slope control  
■ Short circuit protection  
The device is equipped with an integrated Zener  
diodes clamp for fast inductive load current  
recirculation. This structure limits the output  
voltage during the recirculation phase to 50V.  
■ Open load detection in ON and OFF condition  
■ Load bypass detection  
■ Overload disable  
■ Signal and power ground loss shutdown  
■ Selective overtemperature shutdown  
■ Electrostatic discharge (ESD) protection  
The device is self-protected against short circuit  
at the outputs and overtemperature.  
For the real time error diagnosis, the voltage and  
the current of the outputs are compared with  
internally fixed thresholds to recognize open load  
in OFF and ON conditions.  
Description  
The L9349 is a monolithic IC designed to drive  
inductive loads in low side configurations like  
hydraulic valves used in ABS systems.  
The output voltages are also compared with each  
other in OFF condition with a fixed offset, in order  
to recognize load bypasses.  
Particular care has been taken to protect the  
device against failures, to avoid electromagnetic  
interferences and to offer extensive real time  
diagnostics.  
If the over load current threshold is exceeded, the  
output current will be limited internally during the  
diagnostic overload delay switch-off time.  
All four channels are monitored with a status  
output. The diagnostic output level in connection  
with different enable and input conditions allows it  
to recognize the different fail states.  
The internal pull down current source at the  
ENable and INput pins assures, that the device is  
switched off, in case of open input conditions.  
An output voltage slope limitation is implemented  
to reduce the EMI.
