STBY and CTL Pin Functions
The STBY and CTL pins function as active high control inputs.
There is no ESD protection diode inserted between the VCC line and the STBY pin. This means that there is no
magnitude relationship between the STBY and CTL pin voltage and the VCC voltage.
SCP Pin
If of the FB1 to FB6 outputs goes to the high level due to the load being shorted, the SCP pin starts a charging operation
and the protection circuit will operate if the shorted state is not resolved during the period tSCP. (If the protection
circuit operates, all outputs are turned off.) If the application does not use this protection circuit, the SCP pin must be
shorted to ground with a line that is as short as possible.
