DESCRIPTION
L9825 is a Octal Low-Side Driver Circuit, dedicated
for automotive applications. Output voltage clamping
is provided for flyback current recirculation, when in-
ductive loads are driven. Chip Select and Serial Pe-
ripheral Interface for outputs control and diagnostic
data transfer. Parallel Control inputs for two outputs.
