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-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 (can be disabled by applying a logic high to BP_DIS).

Each port has a current-limited 107-m N-channel MOSFET 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.

For applications not requiring a 5-V regulator controller, use the TPS2074 or TPS2075 device.
