5V - 1.2V CIRCUIT
I(Max)≠ 1.5A
Option: Reserved for EMI improvement
Option: ESD Protection
(1)100K pull down resistor shall be put on CTL
pin for charging (DCP) function.
(2)If AIC1519-1(High active) is used, 100K pull
down resistor shall be put on CTL pin.
100K pull high resistor shall be put on CTL pin
for charging(DCP) function.
Option: EEPROM
Option:R35&R36 reserved for
GL3520-20/GL3521
Discharge resistance (R67&R68&R69&R70) is not needed while
Hub's upstream port is not removable.(embedded applications)
When DCP is enabled,
connect RESET to Vcc
R3 for Normal
Hub Function
If Hub is supplied by bus-power,
please still tighten PSELF to high in case Hub is connected with high-power devices.
