Product details
Overview
TPS2010PWR from Texas Instruments is a 95-mΩ max (at 5.5 V) high-side N-channel MOSFET power-distribution switch with logic-compatible enable input, short-circuit current limiting of 0.4 A (typical at 25°C), thermal shutdown at ~180°C, and 2.7–5.5 V operating range. It serves as a protected load-switching element in USB peripheral power rails and low-voltage embedded systems.
For engineers reviewing the TPS2010PWR datasheet, TPS2010PWR pinout, TPS2010PWR application, or TPS2010PWR equivalent, key selection criteria include its SOIC-8 package compatibility with Siliconix Littlefoot™ PMOS switches (GND-connected), controlled 2–4 ms rise/fall times for EMI reduction, and 10 µA standby current under disable condition.
Technical Context
The TPS2010PWR integrates an internal 100-kHz charge pump enabling gate drive above source voltage - critical for full enhancement of its high-side N-MOSFET across the full 2.7–5.5 V input range. Its driver circuit actively shapes output voltage transitions to limit di/dt and suppress electromagnetic interference.
Current limiting operates via a dedicated sense FET that triggers constant-current mode when load exceeds 0.4 A (typical); thermal protection activates at ~180°C junction temperature with ~20°C hysteresis, enabling automatic recovery after fault removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-state resistance | 95 mΩ max at 5.5 V input - limits conduction loss to ≤200 mW at 0.4 A load |
| Short-circuit current limit | 0.4 A typical at 25°C - defines safe sustained overload threshold before thermal shutdown |
| Input voltage range | 2.7 V to 5.5 V - supports single-cell Li-ion, USB 5 V, and 3.3 V system rails |
| Enable logic compatibility | TTL/CMOS-compatible EN pin (0.4 V low, 2 V high) - enables direct microcontroller GPIO control |
| Standby supply current | 10 µA max when disabled - preserves battery life in always-on host systems |
| Rise/fall time | 3.5–4 ms (with 1 µF load) - reduces peak inrush current and conducted EMI during hot-swap events |
| ESD rating | 12 kV on OUT, 6 kV on all other terminals (HBM) - ensures robustness in handling and board-level integration |
Pinout & Package
TPS2010PWR is housed in an 8-pin SOIC (D) package with gull-wing leads, RoHS-compliant NiPdAu finish, and moisture sensitivity level (MSL) 1 (260°C peak reflow). The package is pin-compatible with Siliconix Littlefoot™ PMOS switches when GND is connected.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal charge pump, driver, and thermal sensor |
| 2,3 | IN | Parallel input voltage pins - reduce trace resistance and power dissipation at high current |
| 4 | EN | Active-low enable: logic low = switch ON; logic high = switch OFF + <10 µA quiescent draw |
| 5–8 | OUT | Parallel output pins - distribute current and minimize voltage drop across bond wires and PCB traces |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | 100-kHz self-contained pump enables full N-MOSFET gate drive down to 2.7 V without external components |
| Controlled switching transients | 2–4 ms rise/fall times prevent large inrush currents into heavy capacitive loads (e.g., USB ports) |
| Thermal shutdown with hysteresis | Shuts off at ~180°C junction temperature; auto-restarts after ~20°C cooldown - avoids latch-up during intermittent faults |
| Dedicated current-sense FET | Replaces lossy sense resistors; enables accurate, low-drift current limiting without added series resistance |
| High ESD tolerance | 12-kV HBM on output pin - protects against electrostatic discharge during connector mating/unmating |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2011D | Higher 1.2 A short-circuit current limit; otherwise identical SOIC-8 footprint and electrical behavior | Suitable where higher sustained load current is required without changing layout or firmware | Select TPS2011D if design requires >0.4 A continuous output while retaining same thermal profile and enable timing |
| TPS2051BDBVR | Lower 90 mΩ RON, 1.5 A current limit, integrated soft-start, but requires external pull-up on EN and lacks 12-kV ESD on OUT | Better suited for noise-sensitive analog rails; less robust for connector-facing outputs | Choose TPS2051BDBVR only when lower RON and programmable soft-start outweigh reduced ESD margin and different enable polarity |
Compared with TPS2010PWR, TPS2011D offers higher current capability in identical packaging and pinout, while TPS2051BDBVR trades ESD robustness and enable simplicity for lower on-resistance and soft-start control - making TPS2010PWR optimal for cost-sensitive, ESD-exposed, fixed-threshold USB and sensor-rail applications.

FAQ
What is the maximum continuous output current supported by the TPS2010PWR?
The TPS2010PWR does not specify a maximum continuous output current beyond its short-circuit limit. Its typical short-circuit current limit is 0.4 A at 25°C, and it operates safely up to this threshold in constant-current mode. Sustained operation near this limit requires thermal derating per the SOIC-8 dissipation rating (464 mW at 70°C ambient). For reliable continuous operation, design loads should remain well below 0.4 A to avoid thermal shutdown.
Does the TPS2010PWR require external components for basic operation?
No, the TPS2010PWR requires no external components for core functionality. Its internal 100-kHz charge pump, current-sense FET, and thermal protection circuits are fully self-contained. A 0.1 µF ceramic bypass capacitor between IN and GND is recommended for stability, and an additional 0.1 µF capacitor on OUT improves ESD immunity - but neither is mandatory for enable/disable or current-limit operation.
How does the TPS2010PWR behave during a short-circuit event?
When a short occurs on the TPS2010PWR output, the current-sense FET detects excess current and forces the N-MOSFET into linear region operation, holding output current at ~0.4 A (typical) while reducing output voltage. If the fault persists, power dissipation raises junction temperature until thermal shutdown (~180°C) disables the switch. Recovery is automatic once junction cools by ~20°C, causing cyclical on/off behavior until the fault is removed.
Is the TPS2010PWR pin-compatible with other members of the TPS201x family?
Yes, the TPS2010PWR shares identical SOIC-8 pinout and package dimensions with TPS2011D, TPS2012D, and TPS2013D. All variants use the same terminal functions (GND, IN×2, EN, OUT×4), enabling direct substitution in layouts where only the current-limit threshold differs - provided thermal and current requirements align with the replacement part's rating.
What is the purpose of the multiple IN and OUT pins on the TPS2010PWR?
The dual IN pins (pins 2 and 3) and quadruple OUT pins (pins 5–8) on the TPS2010PWR reduce effective trace and bond-wire resistance, minimizing voltage drop and localized heating at high load currents. This parallel routing strategy maintains low impedance paths for both input supply and output load connections - essential for stable performance in high-capacitance or high-pulse-current applications like USB hot-plug events.
