Note 1: ’

Σ=1’ means at least one variable is high.

Note 2: ’Fault’ is the logic OR of UVLO and thermal shutdown.

Note 3: ’Cap’ means the pin has a capacitor of appropriate value between it and ground.

Note 4: Positive logic is used.

Note 5: For meanings of the variables, refer to the block diagrams.

Note 6: A blank value means ’don’t care’.
