1 / 54 page  This is information on a product in full production. September 2025 DS11400 Rev 9 1/54 L9301 Automotive octal low side driver or quad low side plus quad high side driver Datasheet - production data Features AEC-Q100 qualified Eight integrated PowerMOS configurable as: – 8 low side ON-OFF with RON(max) = 0.3 Ω @ Tj = 175 °C – High/low side PWM with RON(max) = 0.6 Ω @ Tj = 175 °C and 4 Low side with RON(max) = 0.3 Ω @ Tj = 175 °C Operating battery supply voltage 5 V to 18 V Operating Vdd supply voltage 4.75 V to 5.25 V Logic inputs TTL/CMOS-compatible Output voltage clamping 37 V typ. in low-side configuration SPI interface for outputs control and for diagnosis data communication Additional PWM inputs for 8 outputs Over temperature protection Open load, short to GND, short to VB Overcurrent diagnostics in latched or unlatched mode for each channel Controlled SR for improved EMC behavior 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 Ronmax = 0.6 Ω (DRN1-4, SRC1-4), 4 low side drivers with Ronmax = 0.6 Ω (OUT1-4) and 4 low side drivers with Ronmax = 0.3 Ω (OUT5-8). 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 Ronmax = 0.3 Ω: DRN1//DRN2, DRN3//DRN4, OUT1//OUT2, OUT3//OUT4. In this way there is a total of 8 LS channels for ON-OFF mode with Ronmax = 0.3 Ω. There is also the possibility to connect the OUT1- 4 and OUT5-8 in order to drive in PWM mode a load connected to VB or GND without the necessity of a freewheeling diode. In this case the Ronmax = 0.6 Ω. The above configuration can be driven by parallel input or SPI command. Through the SPI it is possible to configure the device parameters like configuration, Slew-rate, Overcurrent threshold, to send the drivers commands and to read back the diagnosis results. .
