L9301 Automotive octal low side driver or quad low side plus quad hig h side driver Datasheet - production data Description The L9301 is a SPI (Serial Peripheral Interface) controlled octal channel with 4 high/low and 4 low side drivers with the possibility to use four integrated PowerMOS as recirculation diodes for PWM load driving. L9301 contains 12 PowerMOS: 4 configurable High/Low side drivers with R = 0.6 onmax GAPGPS00337 (DRN1-4, SRC1-4), 4 low side drivers with PowerSSO36 R = 0.6 (OUT1-4) and 4 low side drivers onmax with R = 0.3 (OUT5-8). onmax The power DRN/SRC1-4 and OUT1-4 can be connected in parallel outside the device in order to get 4 low-side drivers with R = 0.3 : onmax Features DRN1//DRN2, DRN3//DRN4, OUT1//OUT2, AEC-Q100 qualified OUT3//OUT4. Eight integrated PowerMOS configurable as: In this way there is a total of 8 LS channels for 8 low side ON-OFF with R = 0.3 ON-OFF mode with R = 0.3 . onmax ON(max) T = 175 C j There is also the possibility to connect the OUT1- High/low side PWM with R = 0.6 ON(max) 4 and OUT5-8 in order to drive in PWM mode a T = 175 C and 4 Low side with j load connected to VB or GND without the R = 0.3 T = 175 C ON(max) j necessity of a freewheeling diode. In this case the Operating battery supply voltage 5 V to 18 V R = 0.6 . onmax Operating V supply voltage 4.75 V to 5.25 V The above configuration can be driven by parallel dd input or SPI command. Logic inputs TTL/CMOS-compatible Output voltage clamping 37 V typ. in low-side Through the SPI it is possible to configure the configuration device parameters like configuration, Slew-rate, Overcurrent threshold, to send the drivers SPI interface for outputs control and for commands and to read back the diagnosis diagnosis data communication results. Additional PWM inputs for 8 outputs . Over temperature protection Table 1.
