description
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
DP0 line control to signal attach/detach of the hub.
These devices are designed to meet bus-powered
and self-powered hub requirements. These
devices are also designed for hybrid hub
implementations and allow for automatic switching
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
Each port has a current-limited 100-mΩ Nchannel
MOSFET high-side power switch for
500 mA self-powered operation. Each port also
has a current-limited 500-mΩ N-channel MOSFET
high-side power switch for 100-mA buspowered
operation. All the N-channel MOSFETs
are designed without parasitic diodes, preventing
current backflow into the inputs.
For applications where a 5-V regulator is needed,
use the TPS2070 or TPS2071 device.
