Product details
Overview
TPS2069CDGN from Texas Instruments is a 1.5-A current-limited power-distribution switch in an 8-pin MSOP-PowerPAD package, designed for USB and peripheral power management. It features ±20% accurate fixed current limiting, 2-µs overcurrent response, reverse current blocking, built-in soft start, and active-low deglitched fault reporting - enabling robust short-circuit protection in 5-V systems such as USB hubs and set-top boxes.
For engineers reviewing the TPS2069CDGN datasheet, TPS2069CDGN pinout, TPS2069CDGN application, or TPS2069CDGN equivalent, this device delivers predictable fault current under heavy capacitive loads or output shorts, supports logic-level enable control (TTL/CMOS compatible), and integrates thermal shutdown with 135°C trip and 20°C hysteresis - critical for reliable hot-swap and load switching design validation.
Technical Context
The TPS2069CDGN uses an internal charge pump to drive an N-channel MOSFET power switch, ensuring low RDS(on) (69 mΩ typical at 25°C) while maintaining voltage regulation across the load. Its constant-current limiting operates independently of input voltage (4.5 V to 5.5 V) and temperature (–40°C to 125°C junction), delivering stable 1.5-A current limit with ±20% accuracy.
It implements undervoltage lockout (UVLO) with 3.75-V rising threshold and 0.14-V hysteresis, preventing erratic turn-on during brownout. Fault reporting is deglitched via a 9-ms internal timer, and the FLT pin asserts low during overcurrent or overtemperature events - both conditions cleared automatically upon recovery.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rated Output Current | 1.5 A continuous - sets maximum safe load current without external current sensing or feedback. |
| RDS(on) (Typical) | 69 mΩ at 25°C - minimizes conduction loss and self-heating under full load (e.g., 78 mW dissipation at 1.5 A). |
| Current Limit Accuracy | ±20% - ensures predictable fault current (1.2–1.8 A range) for consistent upstream supply stress analysis. |
| Overcurrent Response Time | 2 µs - limits energy delivered during short-circuit transients, reducing risk of PCB trace damage or capacitor failure. |
| Enable Logic Compatibility | TTL/CMOS - accepts 0.7 V low / 2.0 V high thresholds, enabling direct interface with microcontrollers and FPGAs. |
| Thermal Shutdown Threshold | 135°C (min) with 20°C hysteresis - provides automatic recovery after overload-induced heating, avoiding latch-up. |
| Input Voltage Range | 4.5 V to 5.5 V - matches standard USB 5-V rail tolerances and supports operation across full industrial ambient range. |
Pinout & Package
TPS2069CDGN is housed in an 8-pin MSOP-PowerPAD (DGN) package (3.00 mm × 3.00 mm), featuring an exposed thermal pad internally connected to GND. The PowerPAD must be soldered to a PCB ground plane for optimal thermal performance (RθJA = 67.1°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | Primary return path for power and logic; connects to PowerPAD for thermal conduction and noise reduction. |
| 2 IN | Power input | 5-V supply input; requires ≥0.1-µF ceramic bypass capacitor placed adjacent to pin for stability. |
| 3 IN | Power input (dual-source) | Second IN pin enables parallel routing of high-current input traces; electrically tied internally to Pin 2. |
| 4 EN/EN | Logic enable input | Active-high enable (logic high turns on switch); TTL/CMOS compatible; must not float. |
| 5 FLT | Fault indicator output | Open-drain, active-low signal asserted during overcurrent or overtemperature; requires external pull-up. |
| 6 OUT | Switched power output | Drives load; current-limited to 1.5 A; includes reverse current blocking when disabled. |
| 7 OUT | Switched power output (redundant) | Electrically tied to Pin 6; used for high-current PCB layout routing flexibility. |
| 8 OUT | Switched power output (redundant) | Electrically tied to Pins 6–7; supports multi-layer trace fanout and thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft start | Controls output rise/fall times (tR ≈ 0.7 ms, tF ≈ 0.43 ms) to suppress inrush current into large capacitive loads (e.g., USB ports). |
| Reverse current blocking | Prevents backflow from OUT to IN when disabled - eliminates need for external blocking diodes in shared-bus systems. |
| Deglitched fault reporting | 9-ms FLT deglitch window rejects transient overloads (e.g., plug-in surges), preventing false system shutdowns. |
| UL Listed & CB File E169910 | Meets safety certification requirements for end-equipment compliance without additional isolation components. |
| Output discharge (TPS2069C variant) | Integrated 470-Ω pulldown (RPD) discharges load capacitance when disabled - avoids floating voltage on downstream circuits. |
Applications
| USB Hub Port Protection | Set-Top Box Peripheral Power |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2069CDBV | Same 1.5-A rating and feature set, but in 5-pin SOT-23 package (RθJA = 220.4°C/W); no PowerPAD; single IN/OUT pins. | Suitable for space-constrained, lower-power applications where thermal margin allows higher junction temperature rise. | Select TPS2069CDBV only if board area is critical and peak load duration is short; DGN offers superior thermal performance for sustained 1.5-A operation. |
| TPS2069C-2DGN | Identical DGN package and pinout, but lacks output discharge (RPD); otherwise identical current limit, timing, and protection. | Preferred where output discharge is unnecessary (e.g., no downstream hold-up capacitance) or where faster turnoff is required. | Choose TPS2069C-2DGN when load capacitance is minimal and FLT-based fault handling suffices; TPS2069CDGN adds safe discharge for sensitive interfaces. |
Compared with TPS2069CDBV and TPS2069C-2DGN, the TPS2069CDGN uniquely combines 8-pin MSOP-PowerPAD thermal efficiency, integrated output discharge, and full pin compatibility within the TPS20xxC family - making it optimal for thermally demanding, safety-critical USB and peripheral power applications.

FAQ
What is the maximum continuous output current supported by the TPS2069CDGN?
The TPS2069CDGN supports a maximum continuous output current of 1.5 A. This value is guaranteed across the full operating temperature range (–40°C to 125°C junction) and input voltage range (4.5 V to 5.5 V), with ±20% accuracy in current-limit threshold. The device enters constant-current mode above this threshold, limiting fault energy and protecting upstream supplies.
Does the TPS2069CDGN include reverse current blocking functionality?
Yes, the TPS2069CDGN provides inherent reverse current blocking when disabled - preventing current flow from OUT to IN. This eliminates the need for external blocking diodes in shared-bus or multi-rail systems, reducing BOM cost and PCB footprint while maintaining voltage isolation between powered and unpowered sections.
How does the FLT pin behave during overcurrent or overtemperature events on the TPS2069CDGN?
The FLT pin on the TPS2069CDGN is an active-low, open-drain output that asserts low during overcurrent or overtemperature faults. It remains asserted for ≥9 ms (deglitched) to reject transients, then deasserts automatically upon fault clearance. The pin returns high-impedance when the device is in UVLO or fully enabled with no fault condition.
What is the purpose of the PowerPAD in the TPS2069CDGN's DGN package?
The PowerPAD in the TPS2069CDGN's MSOP-PowerPAD package is an exposed thermal pad internally connected to GND. When soldered to a PCB ground plane, it reduces thermal resistance (RθJA = 67.1°C/W), enabling sustained 1.5-A operation without exceeding junction temperature limits - critical for compact, high-density layouts in consumer electronics.
Is the TPS2069CDGN compatible with standard USB 5-V power rails?
Yes, the TPS2069CDGN is explicitly designed for 5-V USB applications, with a recommended input voltage range of 4.5 V to 5.5 V. Its undervoltage lockout (3.75-V threshold), ±20% current limit accuracy, and 2-µs fault response meet USB power-delivery robustness requirements - making it ideal for compliant hub, dock, and peripheral designs.
