Typical Applications
TPS2062CDGNR is suitable for 6 applications: USB Port Power Switching, Hot-Swap Power Distribution, Set-Top Box and Consumer Electronics, Industrial Control Systems, Battery-Powered Devices, Networking Equipment.
USB Port Power Switching
The TPS2062CDGNR is ideal for USB ports on computers, hubs, and peripherals, providing dual-channel power switching with 1A per channel. Its current limiting and short-circuit protection ensure safe power delivery to downstream devices, while the fast 2Β΅s overcurrent response protects the host controller. The active-low enable inputs allow simple logic control, and the output discharge function ensures no residual voltage when disabled. With a 70mΞ© on-resistance, it minimizes voltage drop, maintaining USB voltage levels within specification.
Recommended
Hot-Swap Power Distribution
In hot-swap applications, the TPS2062CDGNR provides controlled power delivery to cards or modules being inserted into a live system. Its soft-start feature limits inrush current, preventing voltage droop on the main supply. The device's current limiting and over-temperature protection safeguard both the switch and the load during fault conditions. The dual-channel configuration allows independent control of two loads, making it suitable for redundant power paths. The wide input range of 2.7V to 5.5V accommodates various system voltages.
Recommended
Set-Top Box and Consumer Electronics
The TPS2062CDGNR is used in set-top boxes, gaming consoles, and smart TVs to switch power to peripheral interfaces such as USB and HDMI. Its low on-resistance reduces power loss, improving energy efficiency. The device's small 8-HVSSOP package saves board space, which is critical in compact consumer electronics. The active-low enable pins can be driven by GPIOs from a system controller, enabling power sequencing. The output discharge function ensures quick discharge of downstream capacitors when the switch is turned off, preventing glitches.
Recommended
Industrial Control Systems
In industrial control systems, the TPS2062CDGNR provides reliable power switching for sensors, actuators, and communication interfaces. Its industrial temperature range of -40Β°C to +125Β°C ensures operation in harsh environments. The device's robust protection features, including overcurrent, short-circuit, and over-temperature, enhance system reliability. The dual-channel design allows two independent loads to be controlled, reducing component count. The reverse current blocking prevents back-feeding when the switch is off, protecting the power source.
Recommended
Battery-Powered Devices
The TPS2062CDGNR is suitable for battery-powered devices where power efficiency and protection are critical. Its low quiescent current and 70mΞ© on-resistance minimize power consumption. The device's under-voltage lockout prevents operation when the battery voltage is too low, protecting the system. The output discharge function ensures the load is fully discharged when the switch is off, preventing unintended operation. The wide input range allows operation from single-cell Li-ion batteries (3.0V to 4.2V) and dual-cell configurations.
Recommended
Networking Equipment
In networking equipment such as routers and switches, the TPS2062CDGNR is used to power USB ports and other peripherals. Its fast overcurrent response protects the system from short circuits, which is essential in high-availability networks. The device's dual-channel configuration allows independent power control for different interfaces. The low on-resistance ensures minimal voltage drop, maintaining signal integrity. The device's small package and surface-mount design are ideal for high-density PCB layouts.

Key Differentiators
- Dual-channel configuration with independent enable pins (vs TPS2060CDGNR)
- Fast overcurrent response time of 2Β΅s (vs NCP380HMUAJAATBG)
- Wide input voltage range of 2.7V to 5.5V (vs AP2822CKETR-G1)
Design Notes
Place input and output capacitors (typically 10Β΅F ceramic) as close to the IN and OUT pins as possible to minimize parasitic inductance and ensure stable operation. The exposed thermal pad (pin 9) must be soldered to a large copper area on the PCB, connected to GND, to enhance heat dissipation. Use multiple vias to connect the pad to the ground plane for improved thermal performance.
The TPS2062CDGNR has a typical on-resistance of 70mΞ©, so at 1A load, the power dissipation is approximately 70mW per channel. Ensure the PCB layout provides adequate copper area to keep the junction temperature within limits. The device includes over-temperature protection, but proper thermal design is essential for reliable operation at high ambient temperatures.
Do not exceed the absolute maximum input voltage of 5.5V. The enable pins are active-low, so ensure they are properly driven to avoid unintended switching. When driving capacitive loads, the soft-start feature limits inrush current, but a large output capacitor may still cause voltage droop on the input supply; consider adding a bulk capacitor at the input. Also, note that the current limit is fixed and not adjustable, so design the system to operate within the 1A continuous rating.
