The L9362 is an low-end four-way driver launched by Infineon. The driver has power limitation, load interrupt and shorted load detection, thermal shutdown, error detection via SPI interface and integrated Z-diodes for output clamping, free running diodes etc.
The L9362 is a quad low-side power switch integrated circuit designed specifically for automotive applications. It features a 5V supply voltage and includes internal failure diagnostics accessible via an SPI interface. The device incorporates current feedback outputs for each power stage to monitor load conditions and includes protection mechanisms such as short-circuit detection, overtemperature protection, and overcurrent protection.
