Product details
Overview
TPS2062ADR from Texas Instruments is a dual-channel, current-limited power-distribution switch featuring two 70 mΩ N-channel MOSFETs, 1 A continuous per-channel output, thermal and short-circuit protection, and active-low enable inputs. It operates from 2.7 V to 5.5 V and delivers precise current limiting (1.2 A min / 2.0 A max) for USB-compliant port power management in embedded host controllers and self-powered hubs.
For engineers reviewing the TPS2062ADR datasheet, TPS2062ADR pinout, TPS2062ADR application, or TPS2062ADR equivalent, key selection considerations include its SOIC-8 (D) package, fixed overcurrent threshold behavior (flat current-limit profile), 0.6 ms typical rise time, and compatibility with 2.7–5.5 V supply rails in space-constrained industrial and peripheral power systems.
Technical Context
The TPS2062ADR integrates an internal charge pump enabling gate drive for both N-channel MOSFETs down to 2.7 V input, eliminating external bias components. Its flat current-limit architecture-distinct from peaking-limit variants like TPS2062ADRB-ensures stable 1.6 A typical short-circuit current without trip-threshold hysteresis.
Each channel features independent thermal sensing (135 °C shutdown, 125 °C recovery), deglitched open-drain OCx fault reporting (8 ms filter), and undervoltage lockout (2.0 V rising threshold). Enable logic is active-low per channel, and PowerPAD™ is absent-confirming D-package (SOIC-8), not DRB (SON-8).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 2 independent, non-ganged power switches |
| rDS(on) per channel | 70 mΩ typical at 25 °C; enables <100 mW conduction loss at 1 A |
| Continuous output current | 1 A per channel; supports sustained USB high-power device loads |
| Current-limit range | 1.2 A min / 2.0 A max (–40 °C to 125 °C); ensures robust short-circuit tolerance |
| Input voltage range | 2.7 V to 5.5 V; compatible with 3.3 V and 5 V system rails |
| Rise time (tr) | 0.6 ms typical; limits inrush surge into heavy capacitive loads (e.g., 100 µF bus capacitance) |
| Standby supply current | ≤1 µA max; enables ultra-low-power disable state for battery-backed systems |
| Operating temperature | –40 °C to 85 °C ambient; validated for industrial-grade deployment |
Pinout & Package
TPS2062ADR uses the SOIC-8 (D) package (JEDEC MS-012AC), with exposed pad omitted-confirmed by absence of PowerPAD™ reference and pin 8 assignment as OC1 (not thermal pad). Pin functions are electrically and mechanically defined per TI SLVS798G Rev G.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for all internal circuitry and MOSFET sources |
| 2 | IN | Main input supply rail (2.7–5.5 V); feeds charge pump and both power switches |
| 3 | EN1 | Active-low enable for Channel 1; logic low = ON, high = OFF (no pull-up required) |
| 4 | EN2 | Active-low enable for Channel 2; independent control enables staggered power sequencing |
| 5 | OC2 | Open-drain overcurrent flag for Channel 2; asserted low during fault or thermal shutdown |
| 6 | OUT2 | Channel 2 switched output; connects to load after internal MOSFET |
| 7 | OUT1 | Channel 1 switched output; isolated path prevents cross-channel fault propagation |
| 8 | OC1 | Open-drain overcurrent flag for Channel 1; debounced 8 ms to reject capacitive-load transients |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 0.6 ms controlled rise time minimizes inrush current into 100 µF+ loads without external RC networks |
| Flat current-limit profile | No IOC/IOS separation-single 1.6 A typical short-circuit limit simplifies fault response timing analysis |
| Thermal fault isolation | Per-channel thermal shutdown (135 °C) and auto-recovery (125 °C) allow one channel to remain operational during overload |
| UVLO with hysteresis | 2.0 V turn-on threshold + 75 mV hysteresis prevents oscillation during brownout or cable-drop conditions |
| Low quiescent current | ≤1 µA standby supply current enables always-on monitoring in energy-sensitive applications |
Applications
| USB Host Port Protection | Industrial I/O Module 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 |
|---|---|---|---|
| TPS2062ADRB | Same SOIC-8 footprint but SON-8 (DRB) package; includes PowerPAD™; uses peaking current-limit (IOC = 2.1–2.45 A, IOS = 1.2–2.0 A) | Higher thermal performance (RθJA = 47.5 °C/W vs 119.3 °C/W); suited for higher ambient or denser layouts | Select TPS2062ADRB only if board layout supports thermal pad connection to ground plane and peaking-limit behavior is acceptable. |
| TPS2061DR | Single-channel variant in SOIC-8; identical electrical specs except channel count and pinout (no EN2/OC2/OUT2) | Reduces cost and complexity when only one protected rail is needed-e.g., single-port USB charging IC | Use TPS2061DR to simplify design and reduce component count where dual-channel functionality is unnecessary. |
Compared with TPS2062ADR, TPS2062ADRB offers superior thermal dissipation but requires PCB redesign for PowerPAD™ grounding, while TPS2061DR reduces integration density but lowers BOM cost and layout complexity for single-rail use cases.

FAQ
What is the current-limit behavior of the TPS2062ADR?
The TPS2062ADR implements a flat current-limit profile: it regulates output current to ~1.6 A typical under short-circuit conditions without a separate overcurrent trip threshold (IOC). This differs from peaking-limit variants (e.g., TPS2062ADRB) and simplifies fault-response timing. The limit ranges from 1.2 A minimum to 2.0 A maximum across –40 °C to 125 °C junction temperature, as specified in TI SLVS798G Section 5.4.
Does the TPS2062ADR require an external capacitor for the charge pump?
No, the TPS2062ADR integrates a self-contained charge pump that operates from the IN supply (2.7–5.5 V) with no external components required. This internal pump generates the gate-drive voltage needed to fully enhance the 70 mΩ N-channel MOSFETs-even at minimum input voltage-enabling reliable switching without added BOM cost or layout area.
How does thermal protection work in the TPS2062ADR?
The TPS2062ADR monitors junction temperature per channel using dedicated thermal sensors. If either channel exceeds 135 °C during overload, that channel shuts down independently while the other remains functional. Recovery occurs automatically once die temperature falls to ~125 °C. This per-channel hysteresis prevents latch-up and maintains partial system operation during transient faults.
Can the TPS2062ADR be used in USB 2.0 applications?
Yes, the TPS2062ADR is explicitly qualified for USB 2.0 applications per TI documentation (Section 8.4). Its 1 A per-channel rating meets high-power USB device requirements, and its UL E169910 listing covers both single and ganged configurations-making it suitable for certified host controllers, self-powered hubs, and bus-powered peripherals requiring robust overcurrent protection.
What is the function of the OCx pins on the TPS2062ADR?
The OC1 and OC2 pins on the TPS2062ADR are open-drain, active-low indicators that assert during overcurrent or thermal fault conditions on their respective channels. Each includes an 8 ms deglitch filter to suppress false triggers from capacitive inrush, and they de-assert immediately upon fault removal. These signals interface directly with microcontroller GPIOs for real-time fault logging and software-controlled recovery.
