What are the key features of TPS2066CDGNR-2?
- Dual independent channels in a compact 8-pin SOIC package for space-constrained designs
- Input voltage range 4.5 V to 5.5 V covering standard USB and 5 V logic rails
- Integrated thermal shutdown and over-current protection for robust load management
- RoHS-compliant, lead-free (Pb-free) construction per JESD-609 e4 requirements
What is TPS2066CDGNR-2 used for?
The TPS2066CDGNR-2 is well-suited for USB power distribution and portable electronics where two separate 5 V power rails must be independently switched and protected. It is commonly deployed in notebook computers, industrial I/O boards, and battery-powered devices to manage load current and prevent damage from short-circuit events. Its compact SOIC-8 footprint makes it a practical choice for space-constrained PCB designs requiring dual-channel load control.

Frequently Asked Questions
What is the input voltage range supported by the TPS2066CDGNR-2?
The TPS2066CDGNR-2 operates over an input voltage range of 4.5 V to 5.5 V, making it directly compatible with USB 5 V power rails and standard 5 V logic supplies used in embedded and portable systems.
How many independent load-switch channels does TPS2066CDGNR-2 provide, and what package does it come in?
The TPS2066CDGNR-2 integrates 2 independent load-switch channels inside an 8-pin small-outline SOIC package (JESD-30 code S-PDSO-G8), allowing designers to control two separate power paths while keeping PCB area minimal.
What protection features make TPS2066CDGNR-2 suitable for USB power distribution applications?
The device includes current limiting and integrated thermal shutdown protection, which guard downstream loads against excessive current draw or short-circuit conditions. These features are critical for USB ports where inrush currents can reach several amps and output faults must be isolated within microseconds to meet USB specification requirements.
Is TPS2066CDGNR-2 compliant with RoHS and lead-free manufacturing requirements?
Yes, TPS2066CDGNR-2 carries a Pb-free code of 'Yes' and a JESD-609 code of e4, confirming it meets RoHS lead-free solder requirements. The part is manufactured without restricted hazardous substances, making it suitable for consumer and industrial products sold in EU and global markets.
