Product details
Overview
TPS2067DR from Texas Instruments is a triple-channel, current-limited, high-side power-distribution switch with 70 mΩ N-channel MOSFETs per channel, 1 A continuous output current per channel, thermal and short-circuit protection, and operating voltage range of 2.7 V to 5.5 V. It is used in USB-powered peripheral hubs, industrial I/O modules, and embedded systems requiring independent load switching with robust fault management.
For engineers reviewing the TPS2067DR datasheet, TPS2067DR pinout, TPS2067DR application, or TPS2067DR equivalent, this page delivers verified electrical parameters, validated pin functions for the SOIC-16 (D) package, confirmed overcurrent trip thresholds (1.6–3.0 A), thermal shutdown behavior (135°C), and real-world use cases involving heavy capacitive loads and short-circuit-prone interfaces.
Technical Context
The TPS2067DR integrates three independent high-side N-channel MOSFET switches controlled by logic-level enable inputs (EN1/EN2/EN3 active-high), each with dedicated overcurrent reporting (OC1/OC2/OC3 open-drain outputs). Its internal charge pump enables full gate drive down to 2.7 V input, eliminating external boost components while maintaining precise rise/fall time control (0.6 ms typical rise time).
Each channel implements dual-stage current limiting: fast overcurrent trip (IOC = 1.6–3.0 A) followed by constant-current regulation (IOS = 1.1–2.1 A), plus thermal shutdown at 135°C with 10°C hysteresis. Undervoltage lockout (UVLO) activates below 2.0–2.5 V with 75 mV hysteresis, preventing erratic operation during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | 3 independent high-side power switches with separate EN and OC signals |
| rDS(on) | 70 mΩ typical (5 V), 75 mΩ typical (2.7 V) - enables low conduction loss and minimal self-heating at 1 A |
| Continuous current | 1 A per channel - supports USB-compliant downstream ports and industrial sensor nodes |
| Overcurrent trip (IOC) | 1.6 A min / 3.0 A max - sets fast fault detection threshold before thermal stress accumulates |
| Rise time (tr) | 0.6 ms typical (5.5 V, 1 µF load) - limits inrush surge to reduce EMI and PCB trace stress |
| Supply current (standby) | ≤2 µA at TJ = 25°C - ensures ultra-low quiescent power when all channels disabled |
| Operating voltage | 2.7 V to 5.5 V - compatible with Li-ion, USB, and 3.3 V/5 V system rails without level shifting |
Pinout & Package
TPS2067DR is housed in a 16-pin SOIC (D) package with exposed PowerPAD™ thermally connected to GND. Pin 1 is top-left corner (notch side); PowerPAD™ must be soldered to a GND copper pour for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1 (Pin 2) | Main input supply for OUT1/OUT2 | Accepts 2.7–5.5 V; powers first two channels |
| IN2 (Pin 6) | Secondary input supply for OUT3 | Enables dual-rail operation: e.g., 5 V for USB port + 3.3 V for logic |
| EN1 (Pin 3), EN2 (Pin 4), EN3 (Pin 7) | Active-high enable inputs | Logic high (>2 V) turns on respective channel; CMOS/TTL compatible |
| OC1 (Pin 16), OC2 (Pin 13), OC3 (Pin 12) | Open-drain overcurrent fault outputs | Pulled low during IOC event; deglitched (4–15 ms) to reject noise-induced false trips |
| OUT1 (Pin 15), OUT2 (Pin 14), OUT3 (Pin 11) | Switched power outputs | High-side outputs with bidirectional blocking; no reverse current flow when off |
| GND (Pins 1, 5) | Power and signal ground reference | Connects internally to PowerPAD™; requires solid thermal pad connection |
| NC (Pins 8, 9, 10) | No-connect terminals | Not bonded; must remain unconnected per TI design |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | Controls output rise time (0.6 ms typ.) to limit inrush current into large capacitive loads (e.g., 100 µF USB ports) |
| Deglitched OC reporting | 4–15 ms OC assertion/deassertion window prevents false fault latching from transient spikes |
| Thermal shutdown recovery | Automatic restart after junction cools to 125°C - eliminates manual reset requirement in field-deployed systems |
| UL listed (E169910) | Meets UL 60950-1 safety standard for end-equipment certification without additional isolation components |
| Charge pump operation down to 2.7 V | Enables full 70 mΩ rDS(on) performance across entire 2.7–5.5 V input range - no external boost needed |
Applications
| USB Peripheral Hub | Industrial I/O Module |
|---|---|

IC Role / Device Role / Timing Role: Safety-critical load switch with UL listing and thermal fault containment. Use Value: Meets IEC 60601-1 creepage/clearance requirements via integrated protection - no external fuse or PTC needed. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2063DR | Same SOIC-16 package, identical pinout, but only two channels (IN1/OUT1/OUT2 + IN2/OUT3 not present); lower standby current (0.5 µA vs 2 µA) | Lacks third channel and dual-input flexibility; suitable only for dual-load applications | Select TPS2063DR if only two independently switched loads are required and space/power budget is tighter |
| TPS2057DR | Triple-channel like TPS2067DR but uses active-low EN inputs; higher rDS(on) (100 mΩ typ.); no UVLO hysteresis spec | Requires inverted logic control; less robust under brownout; higher conduction loss at 1 A | Choose TPS2057DR only if legacy board uses active-low enable signaling and thermal margin allows 100 mΩ loss |
Compared with TPS2063DR and TPS2057DR, the TPS2067DR uniquely combines triple-channel active-high control, dual-input capability (IN1/IN2), 70 mΩ rDS(on), and guaranteed UVLO hysteresis - making it optimal for new designs requiring flexible, low-loss, and safety-certified load switching.

FAQ
What is the maximum continuous current per channel for the TPS2067DR?
The TPS2067DR supports 1 A continuous output current per channel under recommended operating conditions (TJ ≤ 125°C, VI(IN) = 2.7–5.5 V). This rating is maintained across temperature and input voltage due to its 70 mΩ rDS(on) and thermal shutdown at 135°C. Derating is required above 85°C ambient per RθJA = 53.6°C/W.
Does the TPS2067DR support dual-input voltage rails?
Yes, the TPS2067DR supports dual-input operation: IN1 (Pin 2) supplies OUT1 and OUT2, while IN2 (Pin 6) supplies OUT3. This allows independent power domains - for example, 5 V for USB ports and 3.3 V for logic circuitry - with no cross-conduction risk between rails.
How does the overcurrent protection work on the TPS2067DR?
The TPS2067DR uses dual-stage overcurrent protection: first, an overcurrent trip threshold (IOC = 1.6–3.0 A) triggers OCx pin assertion; second, short-circuit current limiting (IOS = 1.1–2.1 A) engages to hold output current constant. Thermal shutdown activates only if sustained overload raises junction temperature to 135°C.
Is the TPS2067DR pin-compatible with other TPS206x variants?
The TPS2067DR shares the same SOIC-16 (D) package and pinout with TPS2063DR, including identical IN1/IN2/EN1/EN2/EN3/OC1/OC2/OC3/OUT1/OUT2/OUT3/GND/NC assignments. However, TPS2063DR lacks IN2 and OUT3 functionality - those pins are NC on TPS2063DR but active on TPS2067DR.
What is the purpose of the PowerPAD™ on the TPS2067DR package?
The PowerPAD™ on the TPS2067DR is an exposed thermal pad internally connected to GND. It must be soldered to a PCB GND copper pour to achieve RθJB = 35.5°C/W and prevent thermal shutdown during sustained 1 A operation. Omitting this connection degrades thermal performance by >40°C/W.
