Description

The TPS204xB/TPS205xB power-distribution switches areintended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices incorporates 70-mΩ N-channel MOSFET power switches for power-distribution systems that require multiple power switches in a single package. Each switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires no external components and allows operation from supplies as low as 2.7 V.

When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low.

TUSB2046B   4-Port Full-Speed Universal Serial Bus Hub   USB - USB HUB CONTROLLERS   The overcurrent protection can be provided by a TPS2044 quad device or a TPS2024 single power switch. It is recommended to use TPS2041B instead of TPS2024 and TPS2044B instead of TPS2044.
See Literature slls413e Recommend keeping theTPS204xB outputs individually connected to all ports instead of ganged together
