Product details
Overview
TPS2062D from Texas Instruments is a dual-channel, current-limited, high-side power-distribution switch featuring two independent 70 mΩ N-channel MOSFETs, 1 A continuous output per channel, thermal and short-circuit protection, and operation from 2.7 V to 5.5 V. It is used in USB peripheral ports, industrial I/O modules, and embedded systems requiring controlled hot-swap capability for capacitive loads.
For engineers reviewing the TPS2062D datasheet, TPS2062D pinout, TPS2062D application, or TPS2062D equivalent, this page delivers verified electrical parameters, validated dual-channel switching behavior, confirmed SOIC-8 package mapping, and real-world overcurrent response timing - all specific to the TPS2062D variant.
Technical Context
The TPS2062D integrates two independent high-side N-channel MOSFETs with internal charge-pump gate drive enabling full enhancement down to 2.7 V input. Each channel features dedicated enable (EN1/EN2) and overcurrent reporting (OC1/OC2) pins, with active-low OC outputs deglitched for 4–15 ms to reject transient faults.
Its flat current-limit architecture maintains constant 1.1–1.9 A output during overload without trip-and-shutdown cycling; thermal shutdown activates only under sustained fault conditions (>135°C junction), with automatic recovery at ≤125°C. The device uses sense-FET current monitoring instead of shunt resistors, preserving low RDS(on) and minimizing power loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | Dual independent high-side switches - enables isolated power control for two downstream rails (e.g., USB VBUS + auxiliary 5V rail). |
| RDS(on) | 70 mΩ typical (D package, 5 V IN) - limits conduction loss to <100 mW at 1 A, reducing thermal load on PCB. |
| Current limit range | 1.1 A min / 1.9 A max (−40°C to +125°C) - ensures robust short-circuit handling across industrial temperature range. |
| Rise time (tr) | 0.6 ms typical (5.5 V IN, 1 µF load) - controls inrush dv/dt to prevent supply droop and EMI spikes during hot-plug events. |
| Supply current (standby) | ≤1 µA max (EN = high/low) - enables ultra-low-power system sleep states without external disconnect circuitry. |
| UVLO threshold | 2.0–2.6 V rising edge - prevents erratic switching during brown-out or battery discharge below functional voltage. |
| Thermal shutdown | 135°C activation / 125°C recovery - provides fail-safe protection against sustained overload without latch-up. |
Pinout & Package
TPS2062D is housed in an 8-pin SOIC (D) package with exposed PowerPAD™ thermally connected to GND. Pin 1 is EN1 (active-low enable for OUT1); Pin 2 is IN (shared input); Pin 3 is EN2 (active-low enable for OUT2); Pin 4 is GND; Pin 5 is OC2 (open-drain, active-low fault flag for OUT2); Pin 6 is OUT2; Pin 7 is OUT1; Pin 8 is OC1 (open-drain, active-low fault flag for OUT1). PowerPAD™ must be soldered to GND copper area for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 (Pin 1) | Logic enable input for OUT1 | Active-low signal - drives OUT1 ON when pulled low; high-impedance when floating or high (switch OFF). |
| IN (Pin 2) | Main power input | Shared 2.7–5.5 V supply for both channels - requires local bulk capacitance near pin for stability. |
| EN2 (Pin 3) | Logic enable input for OUT2 | Independent active-low control - allows asynchronous power sequencing between two loads. |
| GND (Pin 4) | Ground reference | Common return for power, logic, and thermal path - connects internally to PowerPAD™ for heat dissipation. |
| OC2 (Pin 5) | Overcurrent indicator for OUT2 | Open-drain, active-low output - sinks current when OUT2 exceeds current limit; requires external pull-up. |
| OUT2 (Pin 6) | Power-switch output channel 2 | Switched 2.7–5.5 V output - capable of delivering up to 1 A continuously with 70 mΩ RDS(on). |
| OUT1 (Pin 7) | Power-switch output channel 1 | Independent switched output - electrically isolated from OUT2; supports separate load monitoring via OC1. |
| OC1 (Pin 8) | Overcurrent indicator for OUT1 | Dedicated fault flag - enables per-channel diagnostics without cross-talk or shared interrupt latency. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | Controlled 0.6 ms rise time minimizes inrush current surges into heavy capacitive loads (e.g., USB devices with >100 µF input caps). |
| Accurate current limit | 1.1–1.9 A tolerance window ensures predictable fault behavior across temperature and supply voltage - critical for certified USB port compliance. |
| Deglitched OC reporting | 4–15 ms OC assertion/deassertion filter rejects sub-millisecond transients (e.g., connector bounce, ESD-induced glitches) without masking real faults. |
| No OC glitch during power-up | Internal state machine suppresses false OC assertions during VIN ramp-up - eliminates need for external POR circuitry or firmware debouncing. |
| UL listed (E169910) | Meets UL 60950-1 recognition for end-equipment safety certification - reduces qualification effort for industrial and medical applications. |

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 |
|---|---|---|---|
| TPS2062DR | Same silicon, tape-and-reel packaging (SOIC-8, RoHS-compliant); identical electrical specs and pinout. | No functional difference - selected for automated SMT assembly vs. tube-packaged TPS2062D. | Choose TPS2062DR for volume production; TPS2062D for prototyping or low-volume hand-soldering. |
| TPS2052BDR | Lower RDS(on) (50 mΩ typ), higher current limit (1.5–2.5 A), but no OC deglitching or UL listing. | Lacks fault-filtering and safety certification - unsuitable for USB or medical applications requiring glitch immunity or regulatory approval. | Use only in non-certified industrial controls where faster response and lower loss outweigh reliability and compliance needs. |
Compared with TPS2062D, TPS2062DR offers identical performance in automated manufacturing, while TPS2052BDR trades safety features and noise immunity for marginally better conduction efficiency - making TPS2062D the optimal choice for certified, fault-resilient designs.

FAQ
What is the maximum continuous current per channel for the TPS2062D?
The TPS2062D supports 1 A continuous output current per channel across the full operating temperature range (−40°C to +85°C ambient). This rating is maintained with proper PCB thermal design using the PowerPAD™ and adheres to the 70 mΩ RDS(on) specification at 5 V input. Exceeding 1 A may trigger current limiting or thermal shutdown depending on duty cycle and layout.
Does the TPS2062D require external components for gate drive or current sensing?
No, the TPS2062D integrates an internal charge pump for gate drive and a sense-FET for current monitoring - eliminating the need for external boost capacitors, gate resistors, or shunt resistors. Only input/output bulk capacitors and OC pull-up resistors are required for basic operation.
How does the TPS2062D handle short-circuit events on one channel?
When a short occurs on OUT1 or OUT2, the TPS2062D enters constant-current mode at 1.1–1.9 A, holding output voltage low while maintaining regulation. OC1 or OC2 asserts low (deglitched for ≥4 ms) to signal the fault. The unaffected channel continues normal operation - no cross-talk or shutdown propagation occurs.
Is the TPS2062D compatible with 3.3 V logic enable signals?
Yes, the TPS2062D EN1 and EN2 inputs accept TTL- and CMOS-compatible logic levels: VIH ≥ 2.0 V and VIL ≤ 0.8 V over the full supply range (2.7–5.5 V). A 3.3 V microcontroller GPIO can directly drive EN1/EN2 without level shifting.
What thermal derating applies to the TPS2062D in SOIC-8 package?
In the SOIC-8 (D) package, the TPS2062D has RθJA = 119.3°C/W. At 1 A and 5 V input, power dissipation is ~70 mW, resulting in ~8.4°C junction rise above ambient. Full 1 A operation is sustainable up to +85°C ambient if the PowerPAD™ is properly soldered to ≥1 in² GND copper area.
