L9301-TR

L9301-TR is an automotive octal low side driver or quad low side plus quad high side. It is a SPI 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 ordered to get 4 low-side drivers with Ronmax = 0.3 Ω: DRN1//DRN2, DRN3//DRN4, OUT1//OUT2, OUT3//OUT4. 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.
