What are the key features of TPS2023DG4?
- Single-channel high-side MOSFET switch with 2.2 A peak current limit and 1.5 A continuous output current for USB bus-powered port protection
- Integrated over-current, thermal shutdown, under-voltage lockout, and transient protection eliminate the need for external protection components
- Active-low enable input with fault flag output in SOIC-8 package enables simple GPIO control and fault detection from a host MCU
What is TPS2023DG4 used for?
The TPS2023DG4 is designed for USB host ports, USB hubs, and notebook computer docking stations where each downstream port requires independent current-limited power control. Its integrated thermal shutdown and over-current protection guard against short-circuit events on USB cable connections without requiring a host software response. The SOIC-8 package and single-supply 5 V operation allow direct placement close to USB Type-A connectors on motherboard and industrial panel PC designs.

Frequently Asked Questions
What are the continuous and peak current limits for the TPS2023DG4 USB power switch?
The TPS2023DG4 supports a continuous output current of 1.5 A and a peak current limit of 2.2 A, meeting USB 2.0 and USB 3.0 bus-powered device requirements. The internal current-limiting circuitry activates before the device enters thermal shutdown, protecting both the switch and the connected USB peripheral.
Which protection features are built into the TPS2023DG4 to avoid external protection circuitry?
On-chip protections include over-current limiting at 2.2 A, thermal shutdown that activates around 145°C junction temperature, under-voltage lockout below approximately 1.5 V, and transient suppression. These four protection layers replace discrete PTC fuses and external TVS diodes, simplifying USB port circuitry to a single IC.
How does the TPS2023DG4 report fault conditions to a host microcontroller?
The TPS2023DG4 drives an active-low open-drain fault output pin when an over-current or thermal fault is detected. A host MCU GPIO with an internal pull-up can poll or interrupt on this signal to log fault events, notify users, or disable additional circuitry within a few microseconds of the fault condition.
What supply voltage range does the TPS2023DG4 cover for 5V USB and other bus supply designs?
The TPS2023DG4 operates from 2.7 V to 5.5 V, covering the nominal 5 V USB VBUS rail with full 10% voltage tolerance. The lower bound of 2.7 V also allows use in 3.3 V power distribution rails in embedded systems where a lower-voltage switched supply is needed.
