Product details
Overview
TPS2062CDRBR-2 from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for USB and peripheral power management. It delivers 1 A per channel, features 70 mΩ typical on-resistance, fast 2 µs overcurrent response, reverse current blocking, and operates from 4.5 V to 5.5 V - enabling robust short-circuit protection in laptop USB hubs and embedded host controllers.
For engineers reviewing the TPS2062CDRBR-2 datasheet, TPS2062CDRBR-2 pinout, TPS2062CDRBR-2 application, or TPS2062CDRBR-2 equivalent, key selection criteria include its active-low enable logic, absence of output discharge (–2 suffix), SON-8 thermal performance (RθJB = 26.3°C/W), and compatibility with 150 µF load capacitance without inrush overshoot.
Technical Context
The TPS2062CDRBR-2 integrates two independent high-side N-channel MOSFET power switches with internal current-limit regulation and thermal shutdown. Each channel enters constant-current mode at 1.61 A (typical) when load exceeds threshold, sustaining fault current predictably without latch-up.
Its control architecture uses active-low EN1/EN2 inputs with 0.8 V low-level threshold and 2 V high-level threshold, deglitched FLTx open-drain fault outputs with 10 ms assertion delay, and built-in soft-start limiting dI/dt during turn-on - all optimized for bus-powered USB 2.0 compliance and hot-swap safety.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rated Current | 1 A per channel - supports USB downstream port power delivery up to 5 V/1 A without external current sensing. |
| Input Voltage Range | 4.5 V to 5.5 V - matches standard USB 5 V bus tolerance and ensures stable operation across supply ripple. |
| rDS(on) | 73 mΩ typical (25°C), 115 mΩ max (–40°C to 125°C) - determines conduction loss and thermal rise under full load. |
| Overcurrent Response | 2 µs typical - enables rapid current limiting before upstream supply collapse or PCB trace damage. |
| Fault Reporting | Active-low open-drain FLT1/FLT2 with 7–13 ms deglitch - prevents false trips from transient surges during plug insertion. |
| Enable Logic | Active-low EN1/EN2 - simplifies direct interface with microcontroller GPIOs without level-shifting. |
| Output Discharge | Not supported (–2 suffix) - eliminates automatic VOUT-to-GND discharge on disable, preserving hold-up time in downstream LDOs. |
Pinout & Package
TPS2062CDRBR-2 is housed in an 8-pin SON (DRB) package (3.0 mm × 3.0 mm) with exposed PowerPAD™ thermally connected to GND for enhanced heat dissipation. The package supports reflow soldering and achieves RθJB = 26.3°C/W when mounted on 1-in² 2-oz copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference and thermal sink | Primary return path for both channels; must be connected to large PCB ground plane via PowerPAD™ for thermal integrity. |
| IN | Power input | Connects to 4.5–5.5 V source; requires ≥0.1 µF ceramic bypass capacitor placed adjacent to pin. |
| EN1 | Channel 1 enable input | Active-low logic input; drives channel ON when pulled ≤0.8 V; high-impedance when floating (channel OFF). |
| EN2 | Channel 2 enable input | Active-low logic input; independent control allows staggered power-up of dual peripherals. |
| OUT1 | Channel 1 output | Switched 5 V output to load; includes reverse-current blocking to prevent backfeed from downstream circuits. |
| OUT2 | Channel 2 output | Switched 5 V output to second load; electrically isolated from OUT1 except through shared IN/GND paths. |
| FLT1 | Channel 1 fault indicator | Open-drain output pulled low during overcurrent or overtemperature; requires external pull-up resistor (typically 10 kΩ). |
| FLT2 | Channel 2 fault indicator | Independent fault reporting enables per-port diagnostics in multi-peripheral systems like USB hubs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 1 A power switches | Enables discrete control of two USB ports or peripherals with no cross-talk or shared fault propagation. |
| 70 mΩ typical rDS(on) | Reduces power loss to ≤70 mW per channel at 1 A, minimizing self-heating and easing thermal design in compact layouts. |
| Reverse current blocking | Prevents backflow from powered loads (e.g., USB devices with local caps) into the main 5 V rail during power-down sequences. |
| Built-in soft-start | Controls output rise time (0.58–1.15 ms) to limit inrush current into large capacitive loads (e.g., 150 µF), avoiding supply droop. |
| –40°C to 125°C operating range | Validated junction temperature range supports deployment in industrial enclosures and automotive infotainment head units. |
Applications
| USB 2.0 Hub Port Protection | Laptop Peripheral Power Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2062CDRBT | Same 1 A rating and SON-8 package, but includes output discharge (non–2 variant). | Required where automatic VOUT discharge on disable is needed for safety or reset timing. | Select TPS2062CDRBT only if downstream circuitry relies on rapid VOUT decay; otherwise TPS2062CDRBR-2 reduces leakage and improves hold-up. |
| TPS2066CDBVR | 1 A rated, SOIC-8 package (3.9 mm × 4.9 mm), active-high enable, same current limit and rDS(on). | Suitable for legacy board designs using SOIC footprints and existing active-high control logic. | Choose TPS2066CDBVR for drop-in replacement in SOIC-based designs; TPS2062CDRBR-2 offers superior thermal performance and smaller footprint. |
Compared with TPS2062CDRBT and TPS2066CDBVR, the TPS2062CDRBR-2 provides optimal thermal resistance (26.3°C/W) in the smallest package, while its active-low enable and no-output-discharge behavior simplify control logic and improve system-level power retention.

FAQ
What is the maximum continuous current per channel for the TPS2062CDRBR-2?
The TPS2062CDRBR-2 is rated for 1 A continuous output current per channel under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Its current-limit threshold is 1.61 A (typical), with ±20% tolerance, ensuring predictable fault behavior across voltage and temperature ranges.
Does the TPS2062CDRBR-2 support output discharge when disabled?
No, the TPS2062CDRBR-2 does not support output discharge - the "–2" suffix explicitly denotes omission of the internal pulldown resistor. When disabled, OUT1 and OUT2 remain floating, preserving voltage on downstream capacitors unless externally discharged.
What is the thermal resistance (RθJB) of the TPS2062CDRBR-2 in its SON-8 package?
The TPS2062CDRBR-2 in the DRB (SON-8) package has a junction-to-board thermal resistance (RθJB) of 26.3°C/W when mounted on a standard 1-in² 2-oz copper pad. This value assumes full connection of the PowerPAD™ to the PCB ground plane.
How does the TPS2062CDRBR-2 respond to a short-circuit event?
Upon detecting an overcurrent condition, the TPS2062CDRBR-2 enters constant-current mode within 2 µs (typical), limiting output current to ~1.61 A. FLT1 or FLT2 asserts low after a 7–13 ms deglitch period, allowing the host system to diagnose and respond without nuisance tripping.
Can the TPS2062CDRBR-2 be used with 3.3 V logic control signals?
Yes - the TPS2062CDRBR-2's EN1 and EN2 inputs accept logic-low signals down to 0.8 V (max) and logic-high signals up to 5.5 V. A 3.3 V microcontroller GPIO can directly drive EN1/EN2 low (≤0.8 V) to enable the channel, meeting the specified VIH/VIL thresholds.
