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-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 where a 5-V regulator is needed, use the TPS2070 or TPS2071 device.
