Product details
Overview
TPS2041BDGN from Texas Instruments is a single-channel, current-limited power-distribution switch featuring a 70mΩ high-side N-channel MOSFET, 500mA continuous output current, thermal and short-circuit protection, and operation across 2.7V–5.5V input range. It serves as a robust load switch in USB-powered peripherals and embedded power rails where inrush control and fault resilience are critical.
For engineers reviewing the TPS2041BDGN datasheet, TPS2041BDGN pinout, TPS2041BDGN application, or TPS2041BDGN equivalent, key selection factors include its accurate 0.75A–1.25A current-limit threshold, 0.6ms typical rise time, deglitched OC reporting, and HVSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TPS2041BDGN integrates an internal charge pump to drive the high-side MOSFET gate, enabling full enhancement down to 2.7V supply while controlling rise/fall times to suppress inrush surges. Its constant-current limiting activates when load exceeds the trip threshold, pulling the open-drain OC pin low without glitching during power-up.
Thermal shutdown engages at 135°C junction temperature and recovers automatically at 125°C, with hysteresis ensuring stable re-enabling. Undervoltage lockout (UVLO) disables the switch below ~2.3V (rising) with 75mV hysteresis, preventing erratic behavior during brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Output Current | 500 mA - supports sustained loads like USB peripherals or FPGA I/O banks without derating at 85°C ambient. |
| Current Limit Threshold | 0.75 A (min) to 1.25 A (max) - provides precise overcurrent protection with minimal false triggering on capacitive inrush. |
| RDS(on) | 70 mΩ (typ) at 5 V - minimizes conduction loss (≤17.5 mW at 500 mA), reducing thermal stress in compact layouts. |
| Rise Time | 0.6 ms (typ) at 5.5 V - soft-starts heavy capacitive loads (e.g., 100 µF) to limit peak inrush current to <1.5 A. |
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with single Li-ion, 3.3 V logic rails, and USB 5 V bus without external regulators. |
| Standby Supply Current | 1 µA (max) - enables ultra-low-power sleep modes in battery-backed systems without compromising availability. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive cabin applications with no derating required. |
Pinout & Package
HVSSOP-8 package (3.00 mm × 3.00 mm), thermally enhanced with exposed PowerPAD™ connected internally to GND for efficient PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and logic; must be connected to PCB ground plane via PowerPAD™ for thermal integrity. |
| IN | Power input | Accepts 2.7–5.5 V supply; feeds internal charge pump and high-side switch; requires local 0.1 µF decoupling. |
| EN | Enable input | Active-high logic control (VIH ≥ 2 V); drives internal gate driver; high-impedance when floating (default off). |
| OC | Overcurrent flag | Open-drain output asserted low during current limit or thermal shutdown; requires external pull-up for system monitoring. |
| OUT | Switched power output | Delivers controlled current to load; voltage follows IN when enabled, floats when disabled; rated for 6 V max. |
Key Features
| Feature | Design Value |
|---|---|
| 70mΩ RDS(on) | Reduces conduction loss and self-heating, enabling higher current density in thermally constrained designs. |
| Accurate current limit (0.75–1.25 A) | Eliminates need for external current-sense resistors or complex feedback, simplifying BOM and layout. |
| Deglitched OC output | Prevents false fault interrupts during transient events like hot-plug or capacitor charging, improving system reliability. |
| No OC glitch during power-up | Ensures clean initialization in multi-rail systems-no spurious resets or firmware misreads at startup. |
| UL Recognized (E169910) | Meets safety requirements for end-equipment certification without additional isolation or protection components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2051BDGN | Same HVSSOP-8 package and pinout; active-high enable; identical RDS(on), current limit, and protection features. | Designed for systems requiring logic-high enable signal instead of logic-low; otherwise functionally interchangeable. | Select TPS2051BDGN if MCU GPIO defaults high or requires active-high control; no layout change needed. |
| AP2171SG-13 | 500 mA rating, 110 mΩ RDS(on), 2.7–5.5 V range, but lacks deglitched OC and UL recognition. | Suitable for cost-sensitive consumer electronics where safety certification and noise-immune fault reporting are not required. | Choose AP2171SG-13 only for non-safety-critical applications with relaxed EMI and certification needs. |
Compared with TPS2041BDGN, TPS2051BDGN offers identical performance with inverted enable polarity-ideal for direct GPIO replacement-while AP2171SG-13 trades UL recognition and OC deglitching for lower cost in less demanding environments.

FAQ
What is the maximum continuous output current supported by the TPS2041BDGN?
The TPS2041BDGN supports 500 mA continuous output current across its full operating temperature range (–40°C to +85°C). This rating is maintained without derating under recommended conditions (2.7 V–5.5 V input, proper PCB thermal design), making it suitable for powering USB peripherals, sensor nodes, and other medium-current loads where reliability is essential. The device enters constant-current limiting above this threshold.
Does the TPS2041BDGN require external components for basic operation?
No, the TPS2041BDGN operates autonomously with no external components required for core functionality. Its integrated charge pump eliminates the need for external boost capacitors, and the deglitched OC output only requires a pull-up resistor for system-level monitoring. A 0.1 µF ceramic capacitor on the IN pin is recommended for stability but not strictly mandatory for functional operation per datasheet guidelines.
How does the TPS2041BDGN handle short-circuit events?
Upon detecting a short circuit, the TPS2041BDGN immediately limits output current to its specified threshold (0.75–1.25 A), pulling the OC pin low after a 4–15 ms deglitch delay. If the fault persists and junction temperature reaches 135°C, thermal shutdown disables the switch. Recovery occurs automatically once the die cools to 125°C, and the device resumes normal operation only after the short is removed and EN is toggled or UVLO resets.
Is the TPS2041BDGN compatible with 3.3 V logic control signals?
Yes, the TPS2041BDGN's EN pin accepts 3.3 V logic-high signals directly: VIH(min) is 2.0 V over the full supply range (2.7–5.5 V), ensuring reliable activation from standard 3.3 V microcontrollers without level-shifting. Its input current is ≤0.5 µA, imposing negligible loading on GPIO pins, and it remains fully functional across –40°C to +85°C ambient temperatures.
What safety certifications does the TPS2041BDGN hold?
The TPS2041BDGN is UL Recognized under file number E169910, confirming compliance with UL 60950-1 and UL 62368-1 for information technology and audio/video equipment. This certification validates its internal insulation, creepage/clearance, and fault containment-enabling direct use in end products requiring safety agency approval without additional isolation components.
