Product details
Overview
TPS2010PW from Texas Instruments is a 50-mΩ N-channel high-side power distribution switch with 0.3-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, delivers controlled 6.1-ms rise time, and supports hot-plug insertion in USB peripheral ports and embedded system modules.
For engineers reviewing the TPS2010PW datasheet, TPS2010PW pinout, TPS2010PW application, or TPS2010PW equivalent, key selection criteria include its 0.3-A current-limit threshold, 8-pin SOIC vs. 14-pin HTSSOP package options, undervoltage lockout at ~2 V, and absence of drain-source back-gate diode for true high-side isolation.
Technical Context
The TPS2010PW implements an internal charge pump to drive the N-channel MOSFET gate above the source voltage, enabling full enhancement down to 2.7 V input. Its current-sense FET architecture enables precise overload detection without series resistance penalty.
Thermal shutdown activates at ~140°C junction temperature with ~20°C hysteresis, and undervoltage lockout ensures the switch remains off until input exceeds ~2 V - critical for reliable hot-insertion sequencing in powered-backplane systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Short-circuit current limit | 0.3 A at 25°C - sets maximum fault current during output short, defining safe energy dissipation window before thermal shutdown |
| On-resistance (rDS(on)) | 33 mΩ at 5 V, 25°C - determines I²R conduction loss and thermal rise under 0.3-A continuous load |
| Rise time | 6.1 ms typical - limits inrush dv/dt to suppress EMI and prevent supply rail collapse during hot-plug events |
| Input voltage range | 2.7 V to 5.5 V - supports single-supply operation across 3.3-V and 5-V logic domains without external regulation |
| Enable input logic | Active-low, TTL/CMOS compatible - allows direct interfacing with microcontroller GPIO or system enable signals |
| Standby supply current | 10 μA max - enables ultra-low-power disable state for battery-backed or always-on subsystems |
| Operating junction temp | –40°C to 125°C - qualifies for industrial ambient environments with localized heating near power stages |
Pinout & Package
TPS2010PW is available in 14-pin HTSSOP (PWP) package with exposed thermal pad. Pin numbering follows TI standard PWP drawing; device uses surface-mount footprint with 0.65-mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN (Pin 7) | Logic enable input | Active-low control: logic 0 enables switch; logic 1 disables and reduces supply current to ≤10 μA |
| GND (Pin 1) | Power ground reference | Common return for internal charge pump, driver, and current-sense circuitry; must be low-impedance |
| IN (Pins 2–6) | Input power supply | Parallel-connected pins accept up to 5.5 V input; share current to reduce trace resistance and thermal stress |
| OUT (Pins 8–14) | Switched 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 gate drive from 2.7 V input without external components - eliminates need for boost converter or external bias supply |
| Current-limit accuracy | 0.22 A to 0.4 A over temperature - ensures predictable fault response across –40°C to 125°C junction range |
| No back-gate diode | Prevents reverse current flow from OUT to IN when disabled - essential for bidirectional isolation in shared-bus architectures |
| Controlled rise/fall times | 6.1 ms rise / 3.4 ms fall typical - reduces peak inrush current and EMI generation during hot-plug transitions |
| Thermal shutdown hysteresis | ~20°C recovery offset - prevents oscillation during sustained overload; enables automatic recovery after fault removal |
Applications
| USB Peripheral Port Protection | Industrial Sensor Node Power Control |
|---|---|
Use Scenario: Hot-plugging USB peripherals (keyboards, mice, hubs) into powered host systems without causing supply droop or bus reset. IC Role / Device Role / Timing Role: High-side power switch controlling VBUS delivery with controlled 6.1-ms ramp to limit inrush. Use Value: Prevents host supply collapse and USB enumeration failure by limiting peak surge current to <0.3 A during plug-in. | Use Scenario: Remote sensor nodes powered via 3.3-V or 5-V field bus, requiring isolated power enable per sensor channel. IC Role / Device Role / Timing Role: Logic-controlled high-side switch enabling/disabling individual sensor rails with thermal fault containment. Use Value: Enables selective power cycling of failed sensors without affecting other channels; 0.3-A limit prevents cascade faults in multi-node deployments. |
| Embedded Module Hot-Swap Interface | Low-Power IoT Edge Device Power Sequencing |
Use Scenario: Inserting expansion modules (e.g., Wi-Fi, CAN) into live carrier boards while maintaining main system uptime. IC Role / Device Role / Timing Role: Hot-swap controller providing soft-start, UVLO, and short-circuit protection on module VCC rail. Use Value: Eliminates need for discrete RC timing networks; UVLO ensures switch stays off until stable 2.7+ V is present post-insertion. | Use Scenario: Battery-powered edge devices with multiple subsystems (MCU, radio, ADC) requiring independent power gating. IC Role / Device Role / Timing Role: Low-quiescent-current (≤10 μA) enable switch for auxiliary rails during deep-sleep modes. Use Value: Reduces standby power by >99% versus always-on LDOs; active-low EN simplifies MCU GPIO control without pull-up resistors. |
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 |
|---|---|---|---|
| TPS2010AD | Same electrical specs, 8-pin SOIC package (D), higher thermal resistance (172°C/W vs. 125°C/W for PWP) | Better suited for low-density PCBs with ample copper area; less effective for high-ambient or high-duty-cycle loads | Select TPS2010AD for cost-sensitive, space-tolerant designs where thermal margin exceeds 25°C |
| TPS2011APWPR | Higher 0.9-A short-circuit limit, identical PWP package and pinout | Supports heavier capacitive loads (e.g., >1000 μF) but increases fault energy and thermal stress under short | Choose TPS2011APWPR only when load capacitance or steady-state current exceeds 0.3 A - not a drop-in replacement |
Compared with TPS2010PW, TPS2010AD trades thermal performance for lower assembly cost and simpler layout, while TPS2011APWPR offers higher current capability at the expense of reduced fault margin - neither is pin-compatible without verifying board-level thermal design and load profile.

FAQ
What is the short-circuit current limit of the TPS2010PW?
The TPS2010PW has a typical short-circuit output current limit of 0.3 A at 25°C, with a specified range of 0.22 A to 0.4 A across temperature and process variation. This limit is enforced by internal current-sense FET circuitry that drives the MOSFET into constant-current mode during overload, preventing damage while maintaining output regulation. The TPS2010PW sustains this limit until thermal shutdown activates at ~140°C junction temperature.
Does the TPS2010PW require external components for operation?
No, the TPS2010PW requires no external components for basic operation: its internal charge pump eliminates the need for a boost capacitor, and the enable input is directly compatible with 3.3-V/5-V logic. However, TI recommends a 0.01–0.1-μF ceramic bypass capacitor between IN and GND, plus optional bulk capacitance on IN/OUT, to suppress transients and improve short-circuit immunity. These are layout best practices - not functional prerequisites.
What package type is used by the TPS2010PW?
The TPS2010PW uses the 14-pin HTSSOP (PWP) package with exposed thermal pad, measuring 5.0 mm × 4.4 mm × 1.2 mm and featuring 0.65-mm lead pitch. This thermally enhanced package provides lower junction-to-ambient thermal resistance (~125°C/W) compared to the SOIC variant, making it suitable for higher ambient temperatures or sustained 0.3-A loads. The PWP package is RoHS-compliant and moisture-sensitive Level-2.
How does the TPS2010PW handle undervoltage conditions?
When input voltage falls below approximately 2 V, the TPS2010PW's undervoltage lockout (UVLO) circuit forces the power switch into the off state, regardless of EN signal state. This prevents erratic behavior during brownout or hot-removal events. Upon reapplication of input voltage, the UVLO releases only after VI(IN) exceeds ~2 V, ensuring clean startup. Hysteresis of ~100 mV prevents chatter near the threshold.
Is the TPS2010PW pin-compatible with other TPS201xA variants?
Yes, all TPS201xA devices in the same package (e.g., TPS2010PW, TPS2011PW, TPS2012PW, TPS2013PW) share identical pinouts and footprints in the PWP package. However, current-limit thresholds differ: TPS2010PW = 0.3 A, TPS2011PW = 0.9 A, TPS2012PW = 1.5 A, TPS2013PW = 2.2 A. Substituting variants requires verification of load current, thermal margin, and fault-energy handling - they are functionally compatible but not electrically interchangeable without design review.
