  • 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 are 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.

    Key Features

    • 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 Vddsupply 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
