What are the key features of TPS2080DRG4?
- Dual independent high-side MOSFET channels each rated 0.7A continuous from a 2.7V to 5.5V supply rail
- Integrated overcurrent, thermal shutdown, and undervoltage lockout protection eliminating external protection components
- 1A peak current limit per channel protecting downstream loads from inrush and fault currents
- Active-low enable inputs allowing direct logic-level control from 3.3V or 5V microcontroller GPIO pins
- 8-pin SOIC package enabling two independent load switches in a single compact footprint
What is TPS2080DRG4 used for?
The TPS2080DRG4 is used in USB port power management and portable device charging circuits where two independent 0.7A load switches must be individually enabled and protected from overcurrent faults. It powers sensors, display modules, and peripheral sub-systems in battery-operated consumer electronics operating from 3.3V or 5V rails, removing the load entirely when inactive to extend battery life. Industrial handheld instruments and embedded computing boards use its dual-channel architecture to sequence or independently cut power to two subsystems from a single IC.

Frequently Asked Questions
How does TPS2080DRG4 protect downstream loads when a short circuit occurs on one of its output channels?
TPS2080DRG4 limits fault current to approximately 1A peak per channel through its internal current-sense and MOSFET gate-fold-back circuit. If the overload persists, thermal shutdown activates when junction temperature reaches about 140°C, cutting the affected channel and protecting both the load and the IC without blowing an external fuse.
Can TPS2080DRG4 operate correctly from a single-cell Li-Ion battery during its full discharge cycle?
With an operating voltage range of 2.7V to 5.5V, TPS2080DRG4 remains active throughout a single-cell Li-Ion battery's discharge from 4.2V fully charged down to approximately 2.75V near depletion. Undervoltage lockout shuts both channels off cleanly below the lower threshold, preventing undefined switch states as the battery approaches cutoff.
In a USB hub design needing per-port power control, how does TPS2080DRG4 simplify the schematic compared to discrete MOSFET solutions?
TPS2080DRG4 replaces two external P-channel MOSFETs, two gate resistors, two current-sense resistors, and separate overcurrent comparators with a single 8-pin SOIC device. Each channel handles 0.7A continuous at up to 5.5V, covering USB 2.0 low-power port current requirements of 500 mA while saving approximately 80% of the component count.
How do the two enable inputs of TPS2080DRG4 support power sequencing in a multi-rail embedded system?
Each channel has an independent active-low enable pin that accepts logic levels compatible with 3.3V microcontroller GPIOs. A microcontroller firmware routine can assert the enables with a programmable delay of tens of milliseconds between channels, implementing a controlled 2-step power-on sequence to bring up a processor core voltage before enabling peripheral I/O rails.
