Product details
Overview
TPS2052BDGNRG4 from Texas Instruments is a dual-channel, current-limited power-distribution switch featuring two 70mΩ high-side N-channel MOSFETs, 500mA continuous output per channel, thermal and short-circuit protection, and operation from 2.7V to 5.5V. It serves as a smart load switch in USB-powered peripherals and embedded systems with heavy capacitive loads.
For engineers reviewing the TPS2052BDGNRG4 datasheet, TPS2052BDGNRG4 pinout, TPS2052BDGNRG4 application, or TPS2052BDGNRG4 equivalent, key selection criteria include per-channel current limiting (0.75A–1.25A), fast 0.6ms typical rise time, undervoltage lockout (2.0–2.6V), deglitched OC reporting, and HVSSOP-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TPS2052BDGNRG4 integrates an internal charge pump to drive the gate of each 70mΩ N-channel MOSFET, enabling full enhancement down to 2.7V input while controlling rise/fall times to suppress inrush current. Each channel operates independently with active-high enable inputs (EN1/EN2) and dedicated open-drain overcurrent outputs (OC1/OC2).
Under overload, it enters constant-current mode at 1A typical limit (0.75A min / 1.25A max); sustained faults trigger thermal shutdown at 135°C with 10°C hysteresis and automatic recovery. Undervoltage lockout prevents operation below ~2.3V, and OC outputs are deglitched for 4–15ms to reject transient faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | Dual independent high-side switches with separate EN and OC pins per channel |
| rDS(on) | 70 mΩ typical at 5V input - enables low conduction loss and minimal self-heating at 500mA |
| Current limit | 0.75A minimum to 1.25A maximum - ensures predictable fault current under short-circuit conditions |
| Input voltage range | 2.7V to 5.5V - supports single-supply operation across USB 2.0/3.0, 3.3V logic, and battery-backed systems |
| Rise time | 0.6 ms typical - limits inrush di/dt into large capacitive loads (e.g., 100µF downstream rails) |
| Standby current | 1 µA maximum - preserves system-level battery life during sleep or disable states |
| Operating temp | –40°C to +85°C ambient - qualified for industrial and consumer-grade embedded applications |
Pinout & Package
HVSSOP-8 package (3.00mm × 3.00mm body, 0.65mm pitch), thermally enhanced with PowerPAD™ internally connected to GND for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common return path for power and logic; PowerPAD™ must be soldered to GND copper pour |
| IN | Power input | Single shared input rail for both channels; accepts 2.7–5.5V supply |
| EN1 | Channel 1 enable | Active-high logic input; controls switching of OUT1 only |
| EN2 | Channel 2 enable | Active-high logic input; controls switching of OUT2 only |
| OC1 | Channel 1 fault flag | Open-drain output pulled low during overcurrent or thermal shutdown on OUT1 |
| OUT1 | Channel 1 output | Switched high-side output delivering up to 500mA to load |
| OUT2 | Channel 2 output | Switched high-side output delivering up to 500mA to load |
| OC2 | Channel 2 fault flag | Open-drain output pulled low during overcurrent or thermal shutdown on OUT2 |
Key Features
| Feature | Design Value |
|---|---|
| Accurate current limiting | Guaranteed 0.75A–1.25A trip window ensures consistent fault response across voltage/temperature |
| Thermal shutdown with hysteresis | 135°C trip / 125°C recovery prevents latch-up and enables safe auto-restart after cooling |
| Undervoltage lockout (UVLO) | Prevents erratic switching below ~2.3V, eliminating brownout-induced misoperation |
| OC deglitching | 4–15ms filtering rejects noise-induced false trips without delaying genuine fault detection |
| Charge pump gate drive | Enables full MOSFET enhancement from 2.7V input-no external components required |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel power-switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2052BDRBR | Same electrical specs; SON-8 package (3.0×3.0mm) with bottom-side thermal pad instead of HVSSOP PowerPAD™ | Requires different PCB land pattern and reflow profile; better thermal performance (RθJB = 14.2°C/W vs 35.5°C/W) | Select for higher-power density designs where board-level thermal management prioritizes bottom-side conduction |
| TPS2042BDR | Identical pinout and function but rated for 0.75A–1.25A current limit with no UL recognition for ganged configuration | Lacks UL E169910 recognition for ganged use cases requiring safety certification | Select when UL ganged-configuration compliance is not required and cost sensitivity outweighs certification needs |
Compared with TPS2052BDGNRG4, TPS2052BDRBR offers superior thermal resistance but requires layout revision, while TPS2042BDR provides identical functionality without UL ganged approval-making the G4 variant optimal for certified industrial USB applications demanding reliability and regulatory alignment.

FAQ
What is the maximum continuous current rating per channel for the TPS2052BDGNRG4?
The TPS2052BDGNRG4 supports 500mA continuous output current per channel under recommended operating conditions (2.7V–5.5V input, –40°C to +85°C ambient). Its current-limit threshold is specified from 0.75A minimum to 1.25A maximum, with 1A typical, ensuring reliable short-circuit protection without nuisance tripping during normal inrush events.
Does the TPS2052BDGNRG4 require external components for gate drive or current limiting?
No, the TPS2052BDGNRG4 integrates a charge pump for MOSFET gate drive and requires no external components to achieve full enhancement from 2.7V input or to enforce its factory-trimmed current limit. Only input/output bypass capacitors (e.g., 0.1µF ceramic + 22µF bulk) are recommended per channel for stability and inrush control.
How does the overcurrent (OC) reporting work on the TPS2052BDGNRG4?
The TPS2052BDGNRG4 provides two independent open-drain OC outputs (OC1 and OC2), each pulled low during overcurrent or thermal shutdown on its respective channel. These outputs are deglitched for 4–15ms to reject noise, and remain asserted until the fault condition clears and the device recovers-enabling direct microcontroller GPIO monitoring without additional debouncing circuitry.
Is the TPS2052BDGNRG4 UL-recognized, and for what configurations?
Yes, the TPS2052BDGNRG4 carries UL Recognition under File Number E169910, specifically validated for ganged configuration-meaning multiple devices may be used in parallel to increase total current capacity while maintaining safety certification. This distinguishes it from non-G4 variants like TPS2042B, which lack this ganged-use approval.
What thermal performance can be expected from the HVSSOP-8 package of the TPS2052BDGNRG4?
In the HVSSOP-8 (DGN) package, the TPS2052BDGNRG4 achieves a junction-to-board thermal resistance (RθJB) of 35.5°C/W when the PowerPAD™ is properly soldered to a 1-in² GND copper area. This allows sustained 500mA operation at ambient temperatures up to +85°C without exceeding the 125°C maximum junction temperature, assuming standard 2-layer PCB construction.
