Key Features
- 4 independent high-side MOSFET channels switchable individually for flexible power sequencing and load management
- 2.7 V to 5.5 V supply range covers both 3.3 V and 5 V logic systems in a single part
- 0.345 A per channel current capacity suitable for USB accessories, sensor power domains, and peripheral rail switching
- Fixed current-limit threshold protects downstream loads from overcurrent without requiring external fuses
- 16-pin SOIC package integrates 4 discrete load switches into one footprint, reducing PCB area and BOM count
Applications
The TPS2058ADG4 is designed for USB hubs, multi-port charging stations, and embedded system boards that require independent power switching across 4 load domains from a shared 3.3 V or 5 V bus. Each channel's high-side MOSFET switch and current-limit protection enable safe hot-plug management of peripheral devices such as SD cards, camera modules, and RF modules. Industrial field computers and automotive infotainment head units use this IC to sequence power rails during startup and shutdown without discrete MOSFET and gate driver circuits.

Frequently Asked Questions
How many independent load channels does TPS2058ADG4 provide and what per-channel current limit applies?
The TPS2058ADG4 integrates 4 independent high-side MOSFET channels, each rated for 0.345 A continuous current. Each channel has a separate enable input, so power domains can be switched on or off individually. The built-in current-limit threshold protects downstream loads from fault conditions without requiring external polyfuses or resettable fuses.
What supply voltage range does TPS2058ADG4 accept, and does it work directly with both 3.3 V and 5 V USB power rails?
The TPS2058ADG4 operates from 2.7 V to 5.5 V, covering both the 3.3 V logic supply and the 5 V USB VBUS rail. This single-part solution eliminates the need for separate load switch ICs on 3.3 V and 5 V domains, simplifying BOM and reducing board area in multi-voltage embedded platforms.
How does using TPS2058ADG4 compare to placing 4 discrete P-channel MOSFETs for high-side switching in a USB hub design?
Replacing 4 discrete P-channel MOSFETs with TPS2058ADG4 eliminates approximately 8 to 12 additional components—individual gate resistors, pull-up resistors, and layout-sensitive gate drive nodes. The integrated part also provides matched switching characteristics across all 4 channels, built-in current limiting, and a smaller PCB footprint of about 10 mm x 4 mm in SOIC-16, compared to 4 separate SOT-23 or SOT-23-3 MOSFETs totaling similar area with less protection.
Can TPS2058ADG4 be used to switch SD card and peripheral power rails in a portable data logger operating at 3.3 V?
Yes, the TPS2058ADG4 is well-suited for a 3.3 V portable data logger. At 3.3 V supply, the 0.345 A per-channel limit comfortably covers SD card peak inrush (typically under 200 mA) and sensor module active current (often 10 mA to 100 mA). Individual enable control allows the MCU firmware to power-gate inactive peripherals during sleep, reducing standby consumption and extending battery life between 0.1 mA and 1 mA per inactive channel.
