description  
NC – No internal connection  
The TPS2074 and TPS2075 provide a complete  
USB hub power solution by incorporating three  
major functions: current-limited power switches  
for four ports, a 3.3-V 100-mA regulator, and a  
DP0linecontroltosignalattach/detachofthehub.  
†
Pin 9 is active low (BPMODE) forTPS2074  
and active high (BPMODE) for TPS2075.

D–  
These devices are designed to meet bus-pow-  
ered and self-powered hub requirements. These  
devices are also designed for hybrid hub  
implementations and allow for automatic switch-  
ing from self-powered mode to bus-powered  
mode if loss of self-power is experienced. This  
feature can be disabled by applying a logic high to  
the BP_DIS input

D–  
Each port has a current-limited 100-mΩ N-  
channel MOSFET high-side power switch for  
500 mA self-powered operation. Each port also  
has a current-limited 500-mΩ N-channel MOS-  
FET high-side power switch for 100-mA bus-  
powered operation. All the N-channel MOSFETs  
are designed without parasitic diodes, preventing  
current backflow into the inputs.
