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.
