Key Features
- Dual independent output channels with 500 mA current limit per channel for flexible load management
- Wide input voltage range of 4.5 V to 5.5 V suits standard USB and 5 V power rails
- Overcurrent and thermal protection with automatic retry in a compact 8-pin SON package
Applications
The TPS2066ADRBR is well suited for USB power management and hot-plug applications where two independent loads must be protected from overcurrent faults. It is commonly used in notebook computers, tablets, and docking stations to switch 5 V power rails to USB ports, hard drives, or peripheral controllers. Its 500 mA per-channel current limit and fault-flag outputs also make it a reliable choice for industrial embedded systems requiring safe power sequencing.

Frequently Asked Questions
What is the maximum current each channel of the TPS2066ADRBR can supply before the overcurrent protection activates?
Each of the two independent output channels on the TPS2066ADRBR is current-limited to approximately 500 mA. When the output current exceeds this threshold, the switch reduces its gate drive to limit current and asserts a fault flag, protecting downstream loads from damage while alerting the host processor.
Which supply voltage range is compatible with the TPS2066ADRBR, and can it be used directly on a USB 5 V bus?
The TPS2066ADRBR operates from a 4.5 V to 5.5 V input supply, which aligns precisely with the USB specification 5 V bus tolerance of ±5 %. This makes it a direct drop-in solution for distributing USB power to two downstream ports or peripherals without any additional level-shifting circuitry.
How does the 8-pin SON package of the TPS2066ADRBR benefit space-constrained PCB designs?
The 8-pin Small Outline No-lead (SON) package measures roughly 3 mm x 3 mm with an exposed pad for thermal dissipation, requiring less than 10 mm² of board area. This compact footprint is significantly smaller than an equivalent SOIC-8 solution, freeing valuable space in slim notebook, tablet, and portable device designs while still providing 500 mA dual-channel switching.
When would a designer choose the TPS2066ADRBR over a single-channel load switch for USB hub applications?
A designer selects the TPS2066ADRBR when two independent USB downstream ports each need their own 500 mA current-limited switch, because integrating both switches into one 8-pin device reduces component count and BOM cost compared to two discrete single-channel solutions. Independent fault flags on each channel also allow the host controller to disable only the faulted port without interrupting the other 5 V output.
