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.
