Product details
Overview
TPS2062ADRBT from Texas Instruments is a dual-channel, current-limited, high-side power-distribution switch featuring two 70 mΩ N-channel MOSFETs, 1 A continuous per-channel output, 2.7 V to 5.5 V input operation, and integrated thermal/short-circuit protection - used in USB host ports and hot-swap power rails where controlled inrush and fault isolation are critical.
For engineers reviewing the TPS2062ADRBT datasheet, TPS2062ADRBT pinout, TPS2062ADRBT application, or TPS2062ADRBT equivalent, key selection considerations include per-channel enable polarity (active-low), open-drain OCx fault reporting with 8 ms deglitching, soft-start rise time (0.6 ms typ), and SON-8 (DRB) package thermal performance (RθJA = 47.5 °C/W).
Technical Context
The TPS2062ADRBT uses an internal charge pump to drive N-channel MOSFET gates from low input voltages (≥2.7 V), enabling precise control of rise/fall times and eliminating external gate-drive components. Its current-limit architecture operates in constant-current mode above 1.2 A (min), with thermal shutdown triggered at 135 °C and automatic recovery after cooling by ~10 °C.
Each channel features independent enable (EN1/EN2 active-low), open-drain overcurrent flags (OC1/OC2), and undervoltage lockout (UVLO) with 2.0–2.6 V turn-on threshold and 75 mV hysteresis - ensuring robust behavior during brownout and capacitive load startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 1 A per channel - supports sustained USB high-power (500 mA) and dual-peripheral loads without derating. |
| rDS(on) | 70 mΩ typ at 25 °C - minimizes conduction loss (≤70 mW at 1 A) and junction heating in compact layouts. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with 3.3 V and 5 V system rails, including battery-backed and USB-powered designs. |
| Rise Time | 0.6 ms typical - provides controlled soft-start to limit inrush into heavy capacitive loads (e.g., 100 µF downstream). |
| Standby Supply Current | 1 µA max - enables ultra-low-power disable state for energy-sensitive embedded systems. |
| Overcurrent Threshold | 1.2 A min / 2.0 A max - tight tolerance ensures predictable trip behavior across temperature (–40 °C to 85 °C). |
| Thermal Shutdown | 135 °C trigger / 125 °C recovery - protects die during sustained overload while allowing single-channel continuity during partial faults. |
Pinout & Package
The TPS2062ADRBT is housed in an 8-pin SON (Small Outline No-lead) package, DRB variant, with exposed PowerPAD™ thermally connected to GND for optimal heat dissipation (RθJA = 47.5 °C/W). The PowerPAD must be externally soldered to the PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 | Active-low enable input | Logic low enables Channel 1 (IN→OUT1); high-impedance when disabled reduces supply current to ≤1 µA. |
| EN2 | Active-low enable input | Logic low enables Channel 2 (IN→OUT2); independent control allows staggered power-up sequencing. |
| GND | Ground reference | Common return for power, logic, and thermal path; connects directly to PowerPAD for thermal integrity. |
| IN | Power input | Supplies both channels; UVLO disables outputs until voltage exceeds 2.0 V (rising edge). |
| OUT1 | Channel 1 output | Switched 1 A output with 70 mΩ rDS(on); supports bidirectional current flow under specific bias conditions. |
| OUT2 | Channel 2 output | Independent 1 A output with identical specs to OUT1; ganged operation possible via shared EN logic. |
| OC1 | Open-drain fault flag | Active-low signal asserted during overcurrent or thermal fault on Channel 1; 8 ms deglitched to ignore startup transients. |
| OC2 | Open-drain fault flag | Active-low signal for Channel 2; electrically isolated from OC1 - enables per-channel fault diagnostics. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 0.6 ms typical rise time limits inrush current into 100 µF loads, preventing input rail collapse and false UVLO triggering. |
| Deglitched OCx reporting | 8 ms internal filter prevents false overcurrent assertions during capacitive charging, enabling reliable fault detection in USB hubs. |
| Thermal foldback protection | Individual channel shutdown at 135 °C with 10 °C hysteresis allows one channel to remain operational during localized overheating. |
| UL certification | UL File E169910 listed for both single- and ganged-channel configurations - satisfies safety requirements for end-equipment certification. |
| Charge-pump gate drive | Self-contained 2.7 V–5.5 V compatible driver eliminates external boost components and ensures full MOSFET enhancement across input range. |

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 |
|---|---|---|---|
| TPS2062D | SOIC-8 (D package), higher RθJA = 119.3 °C/W, same electrical specs but larger footprint and lower thermal performance. | Suitable for low-power, space-tolerant designs where PCB real estate is available and thermal margin is >25 °C. | Select TPS2062D only if legacy SOIC layout compatibility is required; avoid in thermally constrained USB-C or automotive applications. |
| TPS2066ADRBT | Same DRB-8 package and thermal spec, but EN1/EN2 are active-high - requires inverted logic drive or level-shifting in existing TPS2062ADRBT designs. | Preferred where MCU GPIOs are limited and active-high enables simplify firmware control flow. | Choose TPS2066ADRBT only when redesigning enable logic; not drop-in compatible due to opposite EN polarity. |
Compared with TPS2062D and TPS2066ADRBT, the TPS2062ADRBT uniquely balances compact SON-8 packaging, active-low enable compatibility with most microcontrollers, and industry-leading thermal resistance - making it optimal for high-density, thermally sensitive dual-rail applications.

FAQ
What is the maximum continuous current per channel for the TPS2062ADRBT?
The TPS2062ADRBT supports 1 A continuous current per channel under recommended operating conditions (TA ≤ 85 °C, VIN = 2.7 V to 5.5 V). This rating is maintained across its full ambient temperature range and is validated by TI's electrical characteristics table, where IO is specified as 0 to 1 A in Section 5.2.
Does the TPS2062ADRBT require external components for gate driving?
No, the TPS2062ADRBT integrates a charge pump that generates the necessary gate voltage to fully enhance its internal 70 mΩ N-channel MOSFETs - enabling operation from as low as 2.7 V without external capacitors, boost circuits, or level shifters. This is confirmed in Section 7.1 and Figure 7-2 of the datasheet.
How does the TPS2062ADRBT handle overcurrent faults on individual channels?
The TPS2062ADRBT responds to overcurrent by entering constant-current mode at 1.2–2.0 A per channel, asserting the corresponding open-drain OCx pin (active-low) after an 8 ms deglitch delay. Thermal shutdown activates at 135 °C per channel, with automatic recovery at 125 °C - allowing independent operation of the unaffected channel.
What is the purpose of the PowerPAD™ on the TPS2062ADRBT DRB package?
The PowerPAD™ on the TPS2062ADRBT is an exposed thermal pad on the underside of the DRB-8 package that must be soldered to the PCB ground plane. It reduces junction-to-board thermal resistance to 14.2 °C/W and is required to meet UL certification (File E169910) and achieve the rated 1 A continuous current capability.
Can the TPS2062ADRBT be used in USB 2.0 compliant designs?
Yes, the TPS2062ADRBT is widely deployed in USB 2.0 host ports for current limiting and short-circuit protection. Its 1 A per-channel rating exceeds USB 2.0 high-power device requirements (500 mA), and its soft-start (0.6 ms rise time) and deglitched OCx reporting ensure compliance with USB power-delivery timing and fault-handling specifications.
