VCP  
The TPS2070 and TPS2071 provide a complete  
USB hub power solution by incorporating four  
major functions: current-limited power switches  
for four ports, a 3.3-V 100-mA regulator, a 5-V  
regulator controller for self power, and a DP0 line  
control to signal attach/detach of the hub.  
DGND  
NC – No internal connection  
Pin 12 is active low (BPMODE) for TPS2070 and  
active high (BPMODE) for TPS2071.  
†
‡
simplified hybrid-hub diagram  
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 (can be  
disabled by applying a logic high to BP_DIS).

Each port has a current-limited 107-mΩ N-  
channel MOSFET high-side power switch for  
500 mA self-powered operation. Each port also  
has a current-limited 560-mΩ N-channel MOS-  
FET high-side power switch for 100-mA bus-pow-  
ered operation. All the N-channel MOSFETs are  
designed without parasitic diodes, preventing  
current backflow into the inputs.
