Input/Output Function
Current Limiter Detection Circuit (CLD)

The CLD pin outputs the states of the current limiter and thermal shutdown circuits. If the current limiter
for either channel A or B or the thermal shutdown circuit (shared for both channels) operates, the CLD pin
state changes from low (normal state) to high.
The CLD circuit supports automatic recovery; its output returns to low once the current decreases to a
value below the limit or once the thermal shutdown state is released.
