STMicroelectronics L9301
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. 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.| Part No. | L9301 |

DESCRIPTION
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). In this way there is a total of 8 LS channels for ON-OFF mode with Ronmax = 0.3 Ω.
