Caution:

(1) Connect a capacitor higher than 1 μF to VBUSOUT

(2) Pull Up supply for CHG_DETB (open drain) should be the same VDD as the LSI. Since Pch

protector diode is connected to CHG_DETB, when VDD is OFF, latch up may occur when the signal

level turns high by the pull up.

(3) Make sure to connect capacitor (C cut) to VIDEO pin.

(4) TEST should be either GND or Open.
