NC
7
No internal connection
3.3V_OUT
8
O
3.3-V internal voltage regulator output
BPMODE
9
O
A logic signal that indicates if the outputs source from the bus-powered supply, BPMODE (TPS2074) or BPMODE
(TPS2075), can be used to signal the hub controller.

I
Active-low enable for OUT2
DGND
12
Digital ground
EN3
13
I
Active-low enable for OUT3
EN4
14
I
Active-low enable for OUT4
OC1
15
O
Logic output, overcurrent response for OUT1
OC2
16

O
Logic output, overcurrent response for OUT4
OUT4
19
O
Power switch output for downstream ports
OUT3
20
O
Power switch output for downstream ports
OUT2
21

BP
23
I
Bus power voltage input, connect to VBUS
BP_DIS
24
I
Active-high logic input, disables autoswitch to bus power when self power is disconnected. Connect to BP or GND
Use the following formula to calculate the capacitance needed;
C = (desired pulse width
× 3 × 10–6 / 1.22
Pin 9 is active low for TPS2074 and active high for TPS2075.
