Frequently Asked Questions
How does the TPS2010AD limit current?
The TPS2010AD uses an internal current-sensing circuit to limit output current to approximately 500mA per channel. When an over-current condition is detected, the device reduces gate drive to the internal FET, clamping current and protecting downstream circuitry. The device auto-retries after the fault clears.
Can the TPS2010AD be used in 3.3V systems?
Yes. The TPS2010AD supports a supply voltage range of 2.7V to 5.5V, making it fully compatible with both 3.3V and 5V system rails. Each channel is independently enabled via an active-high logic input, allowing flexible power sequencing in mixed-voltage designs.
What are common applications for the TPS2010AD?
Typical applications include USB power switching in hubs and embedded hosts, power management in bus-powered peripherals, battery-powered IoT devices, and industrial control boards where short-circuit protection on power distribution rails is required.
What package and pin count does the TPS2010AD use?
The TPS2010AD comes in an 8-pin SOIC package (D suffix). The compact footprint and standard 1.27mm pitch make it easy to hand-solder and compatible with standard PCB libraries. A companion MSOP-8 variant (TPS2010AM) is also available for space-constrained designs.
Are compatible alternatives available if the TPS2010AD is out of stock?
Pin-compatible and functionally similar alternatives include the TPS2011AD (single-channel variant), MIC2026-2YM from Microchip (dual USB switch, same SOIC-8), and NCP380 from onsemi. Always verify current limits and enable polarity against your design requirements before substituting.
