What are the key features of TPS2082DR?
- Dual 0.7 A high-side MOSFET channels in a single SOIC-8 package simplifies 2-port USB or load-switch designs with half the component count of discrete solutions
- Built-in overcurrent, thermal, transient, and undervoltage protection on both channels eliminates external current-limiting resistors and protection diodes
- 2.7 V to 5.5 V input range directly supports 3.3 V and 5 V bus architectures in USB hubs, portable devices, and industrial I/O expansion cards
What is TPS2082DR used for?
The TPS2082DR is used in USB hub power distribution, portable battery-powered equipment, and industrial I/O expansion cards where 2 independent load-switch channels with built-in protection are needed in a compact footprint. Its 2.7 V to 5.5 V operating range directly covers 3.3 V and 5 V logic supply rails, making it suitable for protecting USB VBUS lines, peripheral enable circuits, and sensor power sequencing. The integrated overcurrent and thermal protection simplifies compliance testing by eliminating the need for separate polyfuse or PTC components on each power rail.

Frequently Asked Questions
How does the TPS2082DR built-in overcurrent protection respond to a short circuit on a 5 V USB bus compared to a polyfuse approach?
The TPS2082DR senses overcurrent electronically and can disable the affected 0.7 A channel within microseconds of detecting a fault, providing near-instantaneous protection compared to a polyfuse which may take hundreds of milliseconds to trip at currents just above its holding threshold. After fault clearance, the TPS2082DR can auto-retry or remain latched depending on the control logic, whereas a polyfuse requires physical cooling to reset, making the integrated switch more robust in applications with repeated short-circuit events.
Can TPS2082DR operate from a 3.3 V rail in a mixed-voltage system alongside 5 V peripherals?
Yes. The TPS2082DR supports a 2.7 V to 5.5 V input range on each of its 2 independent channels, so channel 1 can switch a 3.3 V rail while channel 2 simultaneously switches a 5 V peripheral rail from a separate supply input — the channels are electrically independent. This dual-voltage capability eliminates the need for 2 separate single-channel switches and their associated input filter components in mixed-voltage IoT gateway or industrial controller designs.
What thermal protection threshold does TPS2082DR use and how does that protect an SOIC-8 board design at high ambient temperatures?
The TPS2082DR's built-in thermal shutdown engages at approximately 140°C junction temperature, automatically disabling both output channels to prevent device destruction. In a 70°C ambient environment with the SOIC-8 package soldered to a standard PCB, the junction-to-ambient thermal resistance limits continuous safe dissipation to roughly 500 mW before the thermal trip activates. This self-protection removes the need for an external NTC thermistor or supervisor circuit to guard against overtemperature conditions in confined enclosures.
