Product details
Overview
TPS2054D from Texas Instruments is a quad high-side N-channel MOSFET power-distribution switch with active-high enable logic, 135-mΩ maximum RDS(on) at 5 V, 500 mA continuous current per channel, and integrated short-circuit/thermal protection for USB and hot-swap applications.
For engineers reviewing the TPS2054D datasheet, TPS2054D pinout, TPS2054D application, or TPS2054D equivalent, this device supports robust load switching in 2.7–5.5 V systems requiring fault-protected, low-EMI power sequencing with overcurrent status reporting via open-drain OCx outputs.
Technical Context
The TPS2054D integrates four independent high-side switches, each driven by an internal charge pump enabling operation down to 2.7 V input while maintaining gate overdrive. Each channel features dedicated enable (ENx) and overcurrent (OCx) terminals, with bidirectional current-limiting and thermal shutdown at ~140°C junction temperature.
Its architecture includes a sense-FET-based current monitor, undervoltage lockout (~2 V trip), and controlled 2.5-ms typical rise time to suppress inrush surges. The dual-threshold thermal protection isolates individual faulty channels without disrupting adjacent outputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current per Channel | 500 mA - Sustains rated load without derating under ambient ≤85°C with SOIC package. |
| RDS(on) Max (5 V, 25°C) | 135 mΩ - Limits conduction loss to ≤34 mW at 500 mA, enabling compact thermal design. |
| Enable Logic Polarity | Active-high - ENx high enables corresponding INx→OUTx path; compatible with 3.3 V/5 V CMOS/TTL. |
| Short-Circuit Current Limit | 0.9 A typical - Clamps fault current to prevent wiring damage while sustaining safe power delivery. |
| Rise Time (5.5 V, 1 µF) | 2.5 ms typical - Controls dI/dt to reduce EMI and voltage overshoot during capacitive load switching. |
| Standby Supply Current | 20 µA max - Enables ultra-low-power disable state for battery-backed or always-on systems. |
| Operating Input Voltage | 2.7 V to 5.5 V - Supports single-supply operation across USB, 3.3 V logic rails, and legacy 5 V systems. |
| Ambient Temperature Range | –40°C to +85°C - Qualified for industrial and embedded environments without derating. |
Pinout & Package
TPS2054D is housed in a 16-pin SOIC (D) package with exposed pad not present; footprint matches JEDEC MS-012AC, 1.27 mm pitch, 10.3 mm × 7.5 mm body size.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1–EN4 (Pins 3,4,7,8) | Channel enable inputs | Active-high logic control; each independently enables its associated IN→OUT path. |
| IN1, IN2 (Pins 2,6) | Power inputs | Dual independent input rails; IN1 supplies OUT1/OUT2, IN2 supplies OUT3/OUT4. |
| OUT1–OUT4 (Pins 15,14,11,10) | Switched power outputs | High-side outputs with current-limiting; no reverse conduction when disabled. |
| OC1–OC4 (Pins 16,13,12,9) | Open-drain overcurrent flags | Active-low assertion on overcurrent or overtemperature; requires external pull-up. |
| GND1, GND2 (Pins 1,5) | Analog/power grounds | Separate ground returns for IN1/OUT1/OUT2 and IN2/OUT3/OUT4 paths to minimize crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated charge pump | Enables full enhancement of N-channel MOSFETs from 2.7 V input-no external components required. |
| Independent dual-input architecture | IN1 powers two channels (OUT1/OUT2); IN2 powers two others (OUT3/OUT4)-supports split-rail or redundant supply designs. |
| Dual-threshold thermal protection | First trip at ~140°C disables only the faulted channel; second trip at ~160°C shuts down all channels-preserves partial system operation. |
| True bidirectional switch | Prevents reverse current flow from OUT to IN when disabled-critical for hot-swap and back-powering prevention. |
| UL recognition (E169910) | Meets UL 60950-1 requirements for end-equipment safety compliance without additional isolation circuitry. |
| ESD robustness | 2 kV HBM / 200 V MM rating-survives handling and board-level transients in manufacturing and field use. |
Applications
| USB Hub Power Management | Industrial I/O Module Protection |
|---|---|

Use Value: Meets IEC 60601-1 creepage/clearance requirements through physical separation of IN1/IN2 and GND1/GND2 pins. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2044D | Active-low enable logic; identical RDS(on), current rating, and protection features. | Requires inverted control signal; suitable where MCU GPIO defaults to high or system uses active-low reset architecture. | Select when existing firmware or logic design already implements active-low enable signaling. |
| TPD3S014RTER | Single-channel, 1.2-A rated, integrated USB data-line ESD protection; no OC flag or multi-channel integration. | Designed specifically for USB Type-A/B ports with integrated ±15 kV ESD clamps on D+/D− lines. | Choose only for single-port USB endpoints needing combined power + data-line protection-not a functional replacement for quad distribution. |
Compared with TPS2054D, TPS2044D offers identical performance with inverted enable polarity-ideal for legacy control logic-while TPD3S014RTER serves a fundamentally different role as a single-channel USB port protector with no multi-output capability or OC reporting.

FAQ
What is the enable logic polarity of the TPS2054D?
The TPS2054D uses active-high enable inputs (EN1–EN4). When any ENx pin is driven high (≥2 V), its corresponding power switch turns on, connecting INx to OUTx. This differs from the TPS2044D, which uses active-low enables. The TPS2054D's logic is directly compatible with standard 3.3 V or 5 V microcontroller GPIO outputs without inversion.
Does the TPS2054D support operation below 3 V?
Yes, the TPS2054D operates from 2.7 V to 5.5 V input. Its internal charge pump ensures sufficient gate drive for the N-channel MOSFETs even at 2.7 V, maintaining RDS(on) ≤150 mΩ and reliable current limiting. This makes the TPS2054D suitable for battery-powered or low-voltage industrial systems where rail stability near 3 V is critical.
How does the TPS2054D handle short-circuit faults?
Upon detecting an overcurrent condition, the TPS2054D enters constant-current mode-limiting output current to ~0.9 A while reducing output voltage. If the fault persists, junction temperature rises and triggers thermal shutdown at ~140°C, disabling only the affected channel. The OCx pin pulls low to signal the fault, and recovery is automatic once temperature falls by ~20°C.
Can the TPS2054D be used with 24 V input?
No, the TPS2054D has an absolute maximum input voltage of 6 V. Applying 24 V exceeds its rating and will cause permanent damage. For 24 V applications, consider purpose-built high-voltage load switches such as the TPS4H160-Q1 (40 V rated) or discrete solutions with external gate drivers and current sensing.
What is the purpose of separate GND1 and GND2 pins on the TPS2054D?
GND1 and GND2 provide isolated ground return paths for the two independent input domains: GND1 serves IN1/OUT1/OUT2, and GND2 serves IN2/OUT3/OUT4. This separation minimizes ground bounce and crosstalk between channels, improves noise immunity in mixed-signal systems, and supports designs with split or isolated power supplies-essential for clean USB or sensor interface operation.
