DESCRIPTION

SHORT CIRCUIT CURRENT LIMITATION

AND SELECTIVE THERMAL SHUTDOWN AT

OUTPUTS 1 AND 2

The L9826 is a Octal Low-Side Driver Circuit, dedicated

for automotive applications. Output voltage clamping is

provided for flyback current recirculation, when induc-

tive loads are driven. Chip Select and Serial Peripheral

Interface for outputs control and diagnostic data trans-

fer. Parallel Control inputs for two outputs.
