The L9826 is a protected octal low-side driver IC designed for the automotive environment.
The 8 -bit serial peripheral interface (SPI) is able to control the devices eight channels and to provide its loads diagnosis. In addition output 1 and 2 can also be controlled through dedicated input pins NON1 and NON2.
Overcurrent and short-circuit protections are present as well as the output voltage clamping which is able to protect the L9826 during operation with inductive loads.
■ 8 channels low side driver with 450 mA output current capability
■ Typical RDSON 1.5 at TJ = 25 °C
■ Parallel control for output 1 and 2
■ SPI control on all outputs
■ Reset function
■ Diagnostic through 8 bit SPI
■ Intrinsic output voltage clamping 50 V (Typ)
protection for inductive load drive
■ Short circuit current limitation and thermal
shutdown for outputs 1 and 2
■ Overcurrent and short circuit shutdown for
outputs 3 to 8
