What are the key features of TPS2041ADR?
- Single-channel load switch operating from 2.7 V to 5.5 V input, ideal for USB, 3.3 V, and 5 V bus protection and power sequencing
- Integrated overcurrent and short-circuit protection with automatic current limiting, removing the need for external fuses in portable and industrial designs
- 8-pin SOIC (JESD-30 R-PDSO-G8) Pb-free package with logic-level enable pin for direct microcontroller GPIO control
What is TPS2041ADR used for?
The TPS2041ADR is used in USB port power management, hot-plug bus switches, and battery-powered portable electronics where controlled power-on sequencing and overcurrent protection are required on rails from 2.7 V to 5.5 V. Its enable input allows a microcontroller GPIO to directly switch a downstream load, making it suitable for power domain control in embedded systems. The SO-8 package and wide input range simplify integration into multi-rail boards requiring per-channel protection.

Frequently Asked Questions
What is the input voltage range of the TPS2041ADR, and which power rails does it support?
The TPS2041ADR accepts input voltages from 2.7 V to 5.5 V, covering standard 3.3 V and 5 V power rails used in USB interfaces, embedded processors, and industrial I/O buses. The single-channel architecture allows independent control of one load, with the enable pin driven directly from a 3.3 V logic GPIO without any level shifting required.
How does the TPS2041ADR protect downstream circuitry from overcurrent faults in USB power delivery applications?
The TPS2041ADR includes an integrated current-limiting circuit that clamps the output current when a short circuit or overload occurs, preventing damage to the downstream load and limiting power dissipation in the switch device itself. For USB host port protection operating at 5 V, this eliminates the need for an external polyfuse or resettable fuse while keeping the PCB footprint to just the 8-pin SOIC outline.
Can the TPS2041ADR be used for power sequencing in a multi-rail embedded system?
Yes. With a logic-level enable input compatible with 3.3 V and 5 V GPIO outputs, the TPS2041ADR can be sequenced by a microcontroller or PMIC to bring up power domains in a defined order. When managing a 3.3 V peripheral rail with loads up to the device's current rating, a simple firmware GPIO toggle at startup controls the rail, supporting power sequencing intervals from microseconds to seconds without additional discrete components.
How does the 8-pin SOIC package of TPS2041ADR compare to smaller alternatives for compact designs?
The SOIC-8 (SOP8 JESD-30 R-PDSO-G8) body measures approximately 5 mm x 4 mm, which is larger than SOT-23-5 load switches but provides a more accessible hand-soldering footprint and greater thermal pad area. For designs where PCB area is not the primary constraint but reliable assembly yield is, the SOIC-8 is preferred. The 2.7 V to 5.5 V input range means the same package fits both 3.3 V and 5 V designs without changing the load switch part number.
