Description

The L9826 is a Octal Low-Side Driver Circuit,

dedicated for automotive applications. Output

voltage clamping is provided for flyback current

recirculation, when inductive loads are driven.

Chip Select and Serial Peripheral Interface for

outputs control and diagnostic data transfer.

Parallel Control inputs for two outputs.
