Note: When the “soft off” function is used, a capacitor must be connected to the SOF pin. If this function is not used, this pin must be left open with absolutely
no signals or lines connected.
Notes on Wiring and Lines
Since large currents flow in the V and ground lines, oscillations may occur on these lines. The following points
CC
should be observed if such oscillations occur.
(1) Lower the line impedances by making them shorter and thicker.
(2) Attach capacitors close to the IC.
(3) If the controller (CPU) is mounted on a separate printed circuit board, insert series resistors (of about 10 kΩ)
between the controller outputs and this IC.
