What is TPS2023DRG4 used for?
The TPS2023DRG4 is widely used in USB hub power switching, laptop docking stations, and embedded computing boards to protect downstream USB ports from overcurrent events and hot-plug transients. Its integrated thermal shutdown and current limiting allow designers to meet USB power specifications without discrete fuses or external PTC thermistors, reducing BOM cost and board space. Industrial and medical equipment designers also use it to provide controlled, fault-protected 5 V power to USB peripherals in mission-critical systems.

Frequently Asked Questions
What current limit does TPS2023DRG4 enforce and how does it protect downstream USB devices?
The TPS2023DRG4 limits peak output current to 2.2 A and continuous output to 1.5 A. When a fault occurs, the internal current-sense circuit pulls the enable low and the thermal shutdown activates above the junction temperature limit, disconnecting the load within microseconds to prevent cable and connector damage in USB 5 V applications.
How does the built-in undervoltage lockout on TPS2023DRG4 benefit USB hub designs?
Undervoltage lockout (UVLO) prevents the switch from turning on when the 5 V supply rail drops below approximately 2.5 V, ensuring USB downstream ports do not attempt enumeration with an insufficient power budget. This avoids bus resets and enumeration failures caused by partial power-up sequencing in multi-port hubs and docking stations.
When is TPS2023DRG4 preferable to a discrete P-channel MOSFET solution for USB port switching?
A discrete P-channel MOSFET requires separate gate drive circuitry, an external current-sense resistor, a comparator for overcurrent detection, and a thermal shutdown network—typically 5 to 8 additional components. The TPS2023DRG4 integrates all of these functions into a single 8-pin SOIC, reducing BOM count, assembly risk, and PCB area by more than 60% versus a discrete implementation.
Can TPS2023DRG4 be used on a 5 V rail shared between multiple USB ports without additional filtering?
Yes. The device's internal MOSFET has low on-resistance, typically around 80 mΩ, which keeps voltage drop under 120 mV at 1.5 A continuous load. Each TPS2023DRG4 instance independently monitors its port, so using one device per USB port on a shared 5 V bus provides isolated fault protection without cross-channel interaction or additional LC filtering between ports.
