FUNCTIONAL DESCRIPTION

response against a voltage fluctuation is the best selection for the V
output drivers. To obtain better THD performance, the stabilization of the power is required.

normal operation. The short protector functions at following accidents.
By setting the STBY pin to “L”, the standby mode is enabled. In the standby mode, the entire functions of the
