The output voltage of the KIA6905F is decided by the input pulse voltage.

When Input A is high and Input B is low, the output current flows though the external relay from output B.

In contrast, When Input A is low and Input B is high, the output current flows though output B from output A.

If the level of the input signal is same, the external relay doesn t work.

Please carefully consider whether the power dissipation is properly designed or not.
