description
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.
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-m鈩?N-
channel MOSFET high-side power switch for
500 mA self-powered operation. Each port also
has a current-limited 560-m鈩?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.
For applications not requiring a 5-V regulator
controller, use the TPS2074 or TPS2075 device.
