Product details
Overview
TPS2011APWPR from Texas Instruments is a 50-mΩ N-channel high-side power distribution switch with 0.9-A short-circuit current limit, logic-level enable input, and integrated thermal/short-circuit protection. It operates from 2.7 V to 5.5 V and delivers controlled 6.1-ms rise time for inrush current limiting in USB-powered peripherals and hot-plug modules.
For engineers reviewing the TPS2011APWPR datasheet, TPS2011APWPR pinout, TPS2011APWPR application, or TPS2011APWPR equivalent, this device serves as a robust, low-quiescent-current (10 μA standby) power switch for systems requiring fault-tolerant load control, ESD-hardened (2-kV HBM) operation, and precise current-limiting behavior across –40°C to 85°C ambient.
Technical Context
The TPS2011APWPR integrates an internal charge pump to drive the N-channel MOSFET gate above source potential, enabling full enhancement down to 2.7-V input. Its current-sense FET architecture provides accurate overload detection without series resistance penalties.
Thermal shutdown activates at ~140°C junction temperature with ~20°C hysteresis, and undervoltage lockout disables the switch below ~2 V input-ensuring safe startup and removal in hot-swap applications. The enable input is active-low and TTL/CMOS-compatible.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Short-Circuit Current Limit | 0.9 A typical at 25°C - sets maximum fault current during output short, enabling predictable thermal stress management |
| On-Resistance (rDS(on)) | 33 mΩ at 5 V, 25°C - minimizes conduction loss and self-heating under 0.9-A continuous load |
| Input Voltage Range | 2.7 V to 5.5 V - supports single-supply operation across USB 2.0, 3.3-V logic rails, and legacy 5-V systems |
| Rise Time (tr) | 6.1 ms typical - limits inrush dv/dt to suppress EMI and prevent supply rail collapse during capacitive load turn-on |
| Standby Supply Current | 10 μA max - enables ultra-low-power system sleep states without compromising fast wake-up capability |
| ESD Protection | 2-kV HBM, 200-V MM - meets industrial IEC 61000-4-2 level requirements for board-level robustness |
| Ambient Temperature Range | –40°C to 85°C - qualified for deployment in commercial and extended-temperature embedded equipment |
Pinout & Package
TPS2011APWPR is housed in a 14-pin TSSOP (PWP) package with exposed thermal pad, optimized for surface-mount assembly and moderate power dissipation (700 mW at 25°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 7) | Active-low enable input | Drives internal bias circuits; logic low enables switch, high disables and reduces supply current to ≤10 μA |
| GND (Pin 1) | Power and signal reference | Common return path for charge pump, driver, and current-sense circuitry; must be low-impedance |
| IN (Pins 2–6) | Power input | Parallel-connected input pins accept up to 5.5 V; share current to reduce trace IR drop and thermal stress |
| OUT (Pins 8–14) | Switched power output | Parallel-connected output pins deliver controlled current to load; no back-gate diode prevents reverse conduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full N-MOSFET enhancement from 2.7 V input-no external components required for gate drive |
| Constant-current foldback | Clamps output at 0.9 A during overloads, maintaining safe power dissipation while sustaining partial functionality |
| Controlled rise/fall timing | 6.1-ms rise and 3.4-ms fall times minimize EMI and eliminate supply rail droop during hot-insertion events |
| No drain-source back-gate diode | Prevents reverse current flow from OUT to IN-critical for isolated power domain integrity in multi-rail systems |
| Undervoltage lockout (UVLO) | Disables switch below ~2 V input-guarantees clean power-up sequencing and prevents erratic behavior during brownout |
Applications
| USB Peripheral Power Switching | Hot-Swappable Module Control |
|---|---|
Use Scenario: Powering USB hubs, card readers, or external storage where host must isolate faulty downstream devices. IC Role / Device Role / Timing Role: High-side load switch enforcing per-port current limiting and graceful fault recovery. Use Value: Prevents bus-wide reset by isolating shorted ports while maintaining upstream communication integrity. |

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 |
|---|---|---|---|
| TPS2011AD | Same electrical specs but in 8-pin SOIC (D) package; higher θJA (172°C/W vs. ~120°C/W for PWP) | Better suited for low-density PCBs with ample thermal copper; less suitable for compact layouts with limited heatsinking | Select when SOIC footprint compatibility or tube packaging is required; verify thermal margin at 0.9-A load |
| TPS2051BDBVR | 500-mA current limit, 100-mΩ rDS(on), SOT-23-5 package; lower cost, smaller size, no thermal pad | Targeted at space-constrained, lower-power applications (e.g., portable sensors); lacks TSSOP thermal performance | Choose for sub-500-mA loads where board area is critical and thermal derating is acceptable |
Compared with TPS2011APWPR, TPS2011AD offers identical functionality in a larger SOIC package with reduced thermal efficiency, while TPS2051BDBVR trades current capacity and thermal robustness for miniaturization-making TPS2011APWPR optimal for 0.9-A hot-swap applications demanding reliability and manufacturability in TSSOP.

FAQ
What is the short-circuit current limit of the TPS2011APWPR?
The TPS2011APWPR has a typical short-circuit output current limit of 0.9 A at 25°C. This value is factory-trimmed and remains stable across input voltages from 2.7 V to 5.5 V and junction temperatures up to 125°C, ensuring consistent fault protection in real-world operating conditions. The TPS2011APWPR enters constant-current mode immediately upon exceeding this threshold.
Does the TPS2011APWPR require external components for gate drive?
No, the TPS2011APWPR integrates a fully self-contained charge pump that generates the necessary gate-drive voltage for its internal N-channel MOSFET. It operates from 2.7 V to 5.5 V input without external capacitors or resistors-simplifying layout and reducing BOM count. This internal architecture is confirmed in the functional block diagram and charge pump description of the TPS2011APWPR datasheet.
What is the thermal shutdown behavior of the TPS2011APWPR?
The TPS2011APWPR shuts down when junction temperature reaches approximately 140°C and automatically recovers once cooled by ~20°C. During thermal fault, the device cycles on/off until the overload is removed. This hysteresis prevents oscillation near trip point and is intrinsic to the TPS2011APWPR's silicon design-no external configuration is needed.
Can the TPS2011APWPR be used with 3.3-V logic enable signals?
Yes-the TPS2011APWPR's EN pin accepts logic-low enable down to 0.5 V (max) and logic-high disable up to 5.5 V, making it fully compatible with both 3.3-V and 5-V CMOS/TTL logic families. Its enable threshold is specified across the full input voltage range (2.7 V to 5.5 V), ensuring reliable operation regardless of system rail voltage.
Is the TPS2011APWPR pin-compatible with other TPS201xA variants?
Yes-TPS2011APWPR shares identical pinout and package (14-pin TSSOP, PWP) with all TPS201xA family members (TPS2010APWPR, TPS2012APWPR, TPS2013APWPR). Only the short-circuit current limit differs between variants; all electrical, timing, and thermal characteristics remain consistent across the family, enabling drop-in replacement within the same current-rating tier.
