Typical Applications
TPS2062DR is suitable for 6 applications: USB Port Power Switching, Hot-Swap Power Distribution, Industrial Control Power Management, Consumer Electronics Power Switching, Networking Equipment Power Distribution, Battery-Powered Devices Power Gating.
USB Port Power Switching
The TPS2062DR provides dual 1A channels with accurate current limiting, making it ideal for USB ports on hubs, laptops, and docking stations. Its 70mΩ on-resistance minimizes voltage drop, ensuring reliable 5V delivery. The active-low enable allows individual port control, and the deglitched OC fault output signals overcurrent events to the host controller. With thermal shutdown, it protects against short circuits and overloads, enhancing system robustness.
Recommended
Hot-Swap Power Distribution
In hot-swap applications, the TPS2062DR's controlled 0.6ms rise time limits inrush current, preventing voltage droops on the main rail. Its accurate current limit (1.1A min, 2.1A max) protects against excessive load currents during insertion. The undervoltage lockout ensures the switch remains off until the input is stable, avoiding glitches. This makes it suitable for PCIe cards, server blades, and other modular systems where safe power connection is critical.
Recommended
Industrial Control Power Management
With a wide operating temperature range of -40°C to 125°C, the TPS2062DR is well-suited for industrial control systems. It can switch power to sensors, actuators, and communication modules, providing overcurrent and thermal protection. The dual channels allow independent control of different subsystems, improving power sequencing and fault isolation. Its low on-resistance reduces power dissipation, enhancing energy efficiency in 24V industrial buses when stepped down.
Recommended
Consumer Electronics Power Switching
In consumer electronics like smart TVs, set-top boxes, and gaming consoles, the TPS2062DR manages power to USB ports and peripheral interfaces. Its small SOIC-8 package fits compact PCB layouts, and the active-low enable simplifies control from application processors. The accurate current limit prevents damage to connected devices, while the fault output allows the system to detect and respond to overcurrent conditions, improving user safety and device longevity.
Recommended
Networking Equipment Power Distribution
The TPS2062DR is used in routers, switches, and access points to distribute power to USB ports, PoE modules, and internal peripherals. Its dual channels enable independent power control for different functional blocks, enhancing system flexibility. The 70mΩ on-resistance ensures minimal voltage drop, maintaining signal integrity in power-sensitive circuits. Thermal shutdown protects against overloads in high-density networking equipment, ensuring reliable operation.
Recommended
Battery-Powered Devices Power Gating
In battery-powered devices like portable electronics and IoT sensors, the TPS2062DR can gate power to different subsystems to extend battery life. Its low quiescent current and 70mΩ on-resistance minimize power loss. The active-low enable allows the microcontroller to shut down unused peripherals, reducing standby power. The undervoltage lockout prevents deep discharge by disabling the switch when battery voltage drops too low.

Key Differentiators
- Dual-channel configuration (vs TPS2066CDR (single-channel))
- Accurate current limit (1.1A min, 2.1A max) (vs TPS2062DR-1 (different current limit))
- Active-low enable with deglitched OC (vs TPS2062CDGNR (same features but different package))
Design Notes
Place input and output capacitors close to the TPS2062DR pins to minimize parasitic inductance and ensure stable operation. Use a 10µF ceramic capacitor on the input and a 10µF ceramic capacitor on each output. Add a 0.1µF bypass capacitor near the IN pin for high-frequency noise suppression.
The TPS2062DR has a thermal resistance of approximately 100°C/W (SOIC-8). At 1A per channel with 70mΩ on-resistance, power dissipation is about 70mW per channel, resulting in a temperature rise of 7°C. This is well within safe limits, but ensure adequate copper pour on the PCB for heat spreading in high-ambient-temperature environments.
Do not leave the EN pin floating; it is active-low, so tie it to GND to enable the switch or drive it with a logic signal. Ensure the input voltage does not exceed 5.5V to avoid damage. The OC pin is an open-drain output; connect a pull-up resistor (e.g., 10kΩ) to the logic supply voltage.
