Product details
Overview
TPS2069CDGNR 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 rail protection. 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 and heavy capacitive load handling in 5-V systems.
For engineers reviewing the TPS2069CDGNR datasheet, TPS2069CDGNR pinout, TPS2069CDGNR application, or TPS2069CDGNR equivalent, this device is selected for high-reliability 5-V power switching where fast fault response, thermal safety, and output discharge control are critical - especially in USB ports, set-top boxes, and digital TVs requiring predictable current limiting under overload.
Technical Context
The TPS2069CDGNR integrates an N-channel MOSFET power switch with internal charge pump gate drive, enabling low RDS(on) (69–98 mΩ) while maintaining 5-V input compatibility. Its constant-current limit architecture operates without peaking, delivering flat IOS = 1.7–2.5 A across –40°C to 85°C ambient.
It implements undervoltage lockout (UVLO) with 3.5–4.0 V rising threshold and 0.14 V hysteresis, plus thermal shutdown at 135°C (in current limit) with 20°C hysteresis. Fault reporting uses a deglitched open-drain FLT pin with 6–12 ms blanking, ensuring noise immunity during transient overloads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rated Output Current | 1.5 A continuous - supports USB 3.0 downstream ports and mid-power peripherals without derating at 85°C ambient. |
| RDS(on) | 69–98 mΩ (typ. 84 mΩ @ 25°C) - minimizes voltage drop and power loss (≤0.19 W at 1.5 A), enabling efficient 5-V distribution. |
| Current Limit Accuracy | ±20% - ensures predictable fault current under all conditions, simplifying system-level overcurrent coordination. |
| Overcurrent Response Time | 2 µs - limits peak fault energy before upstream supply or PCB traces are stressed during short circuits. |
| Enable Logic Compatibility | TTL/CMOS-compatible EN pin (VIH = 2 V min, VIL = 0.7 V max) - interfaces directly with microcontrollers and USB controllers without level shifters. |
| Thermal Shutdown Threshold | 135°C (in current limit), 155°C (not in current limit) - provides self-protection during sustained overload without external sensing. |
| Output Discharge | Integrated pulldown (RPD = 300–800 Ω) - safely discharges load capacitance on disable, preventing floating voltages and latch-up risks. |
Pinout & Package
TPS2069CDGNR is housed in an 8-pin MSOP-PowerPAD (DGN) package (3.00 mm × 3.00 mm), with exposed PowerPAD thermally connected to GND for enhanced heat dissipation. The PowerPAD must be soldered to a PCB ground plane to achieve RθJA = 67.1°C/W (typ.) and sustain full 1.5-A operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 2, 3) | Power input / MOSFET drain | Accepts 4.5–5.5 V supply; requires ≥0.1-µF ceramic capacitor to GND near pins for stability and ESD suppression. |
| OUT (Pins 6, 7, 8) | Power output / MOSFET source | Delivers switched 5-V power to load; multiple pins reduce trace resistance and improve current sharing. |
| GND (Pin 1) | Ground reference | Primary return path; internally tied to PowerPAD - must connect PAD to PCB GND plane for thermal and electrical integrity. |
| EN/EN (Pin 4) | Logic enable input | Active-high control: logic high ≥2 V enables switch; logic low ≤0.7 V disables with <1 µA quiescent current. |
| FLT (Pin 5) | Open-drain fault indicator | Asserts low during overcurrent or overtemperature; deglitched (6–12 ms) to reject noise; requires external pullup. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed current limit with ±20% accuracy | Enables deterministic fault current budgeting - eliminates need for external current-sense resistors or calibration. |
| 2-µs overcurrent response | Prevents destructive energy buildup during short circuits, reducing stress on input capacitors and upstream regulators. |
| Built-in soft-start via controlled rise/fall times | Minimizes inrush current (tR = 0.5–1.0 ms, tF = 0.3–0.55 ms), avoiding brownouts when powering large capacitive loads. |
| Reverse current blocking | Prevents backflow from powered loads into the 5-V rail when disabled - essential for hot-plug USB and shared power domains. |
| UL Listed (E169910) and CB certified | Satisfies end-equipment safety compliance requirements out-of-the-box, accelerating regulatory certification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar power-distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS2069CDBVR | Same 1.5-A rating and feature set, but in 5-pin SOT-23 (DBV) package - higher RθJA (220.4°C/W), no PowerPAD, lower thermal performance. | Preferred for space-constrained, low-power designs where full 1.5-A continuous load is not required or ambient is <60°C. | Select TPS2069CDBVR only if board area is critical and thermal headroom allows; otherwise TPS2069CDGNR delivers superior power handling. |
| TPS2069C-2DGNR | Identical DGN package and pinout, but lacks output discharge (RPD); otherwise matches current limit, RDS(on), and timing. | Used where output discharge is unnecessary (e.g., no large hold-up caps) or where faster turnoff without pulldown is preferred. | Choose TPS2069C-2DGNR only if output discharge is undesirable; TPS2069CDGNR remains optimal for USB and general-purpose use. |
Compared with TPS2069CDBVR and TPS2069C-2DGNR, the TPS2069CDGNR uniquely combines 1.5-A capability, low thermal resistance via PowerPAD, and integrated output discharge - making it the most balanced choice for USB-compliant, thermally demanding, and safety-critical 5-V power switching.

FAQ
What is the maximum continuous output current of the TPS2069CDGNR?
The TPS2069CDGNR is rated for 1.5 A continuous output current under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Its current limit is specified as 1.7–2.5 A (±20%) across –40°C to 85°C ambient, with thermal shutdown engaging at 135°C junction temperature during sustained overload.
Does the TPS2069CDGNR include output discharge functionality?
Yes, the TPS2069CDGNR includes integrated output discharge (RPD = 300–800 Ω) that actively pulls the OUT pin to GND when the device is disabled. This prevents floating voltages on downstream capacitors, reducing risk of latch-up or unintended biasing in connected ICs - a key requirement for USB-compliant designs.
What package type does the TPS2069CDGNR use, and why does it matter?
The TPS2069CDGNR uses the 8-pin MSOP-PowerPAD (DGN) package with an exposed thermal pad. This package achieves RθJA = 67.1°C/W (typ.), significantly lower than the SOT-23 variant - enabling reliable 1.5-A operation in compact, thermally constrained layouts like USB hubs and set-top boxes without forced air cooling.
How does the TPS2069CDGNR respond to a short-circuit event?
Upon short circuit, the TPS2069CDGNR limits output current to its fixed IOS value (1.7–2.5 A) within 2 µs, holding output voltage near zero. If the fault persists, junction temperature rises until thermal shutdown activates at 135°C, cycling the device OFF/ON until the fault clears - protecting both the IC and upstream power source.
Is the TPS2069CDGNR compliant with safety standards for end equipment?
Yes, the TPS2069CDGNR is UL Listed (E169910) and CB certified, meeting key safety requirements for end-user electronics. Its integrated protections - including UVLO, thermal shutdown, reverse current blocking, and deglitched fault reporting - support compliance with IEC 62368-1 and similar regulatory frameworks without additional external components.
