Eight channel valve driver  
Data Brief  
Features  
■ Octal low-side output drivers with protection  
diagnostic  
– 4 x 3A, 160m Ohm typ.  
– 4 x 3A, 200m Ohm typ.  
PowerSO-36  
PowerSSO-36  
■ Programmable channel timer  
■ Clock monitor  
■ 4 channels with Integrated recirculation diodes  
program two output Duty Cycles per channel with  
a block of 16 SPI commands as well as an  
individual duration time for each channel  
actuation. Both information are stored in the PWM  
and in the Counter Configuration Register  
respectively.  
The PWM Controller translates the programmed  
digital duty cycle value in a PWM signal which  
controls the output.  
■ 4 channels with 40V clamp for fast free  
wheeling of inductive loads.  
■ Serial Peripheral Interface with 16bits, up to  
5MHz with diagnosis  
■ Battery compatible supply voltage  
■ Detailed Load diagnosis  
– Over load protection  
– Open load  
The channels 1 to 4 are configured as switching  
channels. To achieve a fast switch off a high  
voltage output clamp is implemented for a rapid  
free-wheeling if the inductive load. The switch on  
time can be programmed via SPI.  
– Under current  
– Under voltage  
– Temperature warning and shutdown  
– Power or signal GND loss  
– Freewheeling diode loss  
All channels are equipped with a load diagnostic.  
This allows to detect an open load in off condition  
as well as a under current in on condition. The  
power stage is protected against over current and  
over temperature. A weak connection in power  
ground, in the recirculation path or in the external  
clock is monitored and leads to a switch off of the  
power stages in case an error occurs. All  
monitored functions can be read out in a serial  
diagnostic protocol dedicated for each channel  
via SPI.  
Description  
The L9375 s a eight channel low side driver with  
integrated recirculation diodes for PWM controlled  
channels 5 to 8. The switching of the channels is  
programmable via a SPI (Serial Peripheral  
Interface). The main time base is given by an  
external clock via CLKin. The Clock Unit monitors  
this external clock and provides the system clock  
for all timings. A Synchronization Unit is used to  
monitor the SPI communication and provide a  
sync signal for the channel activation.
