Product overview
Description
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 device's eight channels and to provide its load's 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.
