Product details
Overview
PI5PD2069UEEX from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch designed for USB bus- and self-powered applications. It delivers 2.1A continuous output current, features accurate 2.85A typical current limiting, operates from 2.7V to 5.5V, and integrates thermal/short-circuit protection with reverse-current blocking - deployed in laptop motherboard USB hub power rails.
For engineers reviewing the PI5PD2069UEEX datasheet, PI5PD2069UEEX pinout, PI5PD2069UEEX application, or PI5PD2069UEEX equivalent, key selection criteria include enable polarity (active-high EN), /OC open-drain fault reporting timing (14ms deglitched assertion), soft-start behavior, RDS(on) temperature dependence, and EP-MSOP-8 thermal performance under sustained 2.1A load.
Technical Context
The PI5PD2069UEEX implements a charge-pump–driven high-side N-MOSFET switch optimized for USB-compliant 5V power distribution. Its internal UVLO circuit enforces turn-on only above ~2.0V input, with 75mV hysteresis, while the deglitched /OC output asserts low after 4–15ms during overcurrent events but responds instantaneously to thermal shutdown at 135°C.
Current limiting is achieved via real-time sense-FET monitoring with trip threshold tightly specified at 2.3–3.4A (2.85A typ.), and thermal recovery occurs automatically at ~125°C with 10°C hysteresis. The device supports hot-plug operation with built-in soft-start and reverse-current blocking, eliminating external body-diode conduction paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70 mΩ @ 5V/3.3V, 1.5A - meets USB voltage-drop spec (≤0.25V at 2.1A) |
| Continuous Current | 2.1 A - maximum steady-state load without thermal derating in EP-MSOP-8 |
| Current Limit Threshold | 2.85 A typical - precise trip point enables reliable USB port compliance |
| Enable Polarity | Active-high EN - compatible with standard logic-level microcontroller GPIOs |
| /OC Response Delay | 4–15 ms deglitch window - suppresses false fault reporting during transient surges |
| Thermal Shutdown | 135°C trigger, 125°C recovery - automatic cycling prevents permanent damage |
| Standby Supply Current | 0.1 µA max @ 25°C - enables ultra-low-power system sleep states |
Pinout & Package
PI5PD2069UEEX is housed in an 8-pin Exposed-Pad MSOP (EP-MSOP-8) package with thermal pad internally connected to GND. The exposed copper pad must be soldered to a PCB ground plane for effective heat dissipation and junction temperature control under 2.1A operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference & thermal sink | Primary return path; connects internally to exposed pad for thermal management |
| 2, 3 IN | Power input | Dual-input pins reduce trace resistance and inductance for high-current 2.7–5.5V supply |
| 4 EN | Enable control (active-high) | Logic-high ≥2V enables switch; logic-low ≤0.8V disables with <0.2µA standby current |
| 5 /OC | Open-drain fault indicator | Asserts low on overcurrent/thermal fault; requires external pull-up (e.g., 100kΩ) |
| 6, 7, 8 OUT | Power output | Three parallel output pins minimize voltage drop and thermal stress at 2.1A load |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | Controls output rise time (0.6ms typ.) to limit inrush current into capacitive USB loads |
| Reverse current blocking | Prevents backflow from OUT to IN when disabled - eliminates need for external blocking diode |
| No /OC glitch at power-up | Ensures clean fault reporting during system initialization without spurious assertions |
| UL Recognized (E341484) | Validated for safety-critical end-equipment including consumer and industrial USB hubs |
| Charge-pump gate drive | Enables full enhancement of N-MOSFET from low 2.7V input - no external boost required |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current-limited power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IPW | Integrated USB 2.0 hub + power switches; dual 500mA channels; no standalone /OC reporting | Replaces discrete switch + controller in full hub IC designs - not pin-compatible | Select when consolidating hub logic and power control; avoid if discrete fault visibility is required |
| TPS2051BDBVR | 2.3A limit, 95mΩ RDS(on), active-low /EN, SOIC-8 only, no reverse-current blocking | Requires external reverse-blocking diode; lacks thermal hysteresis and UL recognition | Use where cost is critical and thermal margin >15°C exists; verify reverse leakage in battery systems |
Compared with TUSB2036IPW and TPS2051BDBVR, PI5PD2069UEEX provides superior USB-specific integration - including UL recognition, reverse-current blocking, and precise 2.85A current limiting - in a thermally enhanced EP-MSOP-8 package ideal for space-constrained, safety-certified designs.

FAQ
What is the enable logic polarity for PI5PD2069UEEX?
The PI5PD2069UEEX uses active-high enable (EN): the internal power switch turns on when EN voltage exceeds 2.0V (typical VIH), and turns off when EN falls below 0.8V (VIL). This differs from the pin-compatible PI5PD2068, which uses active-low /EN - correct logic level alignment is essential for functional operation.
Does PI5PD2069UEEX require an external charge pump or gate driver?
No. The device integrates a charge-pump circuit that generates sufficient gate voltage to fully enhance the internal 70mΩ N-channel MOSFET even at minimum 2.7V input - eliminating external components and simplifying layout for USB 5V and battery-backed 3.3V applications.
How does the /OC pin behave during thermal shutdown versus overcurrent?
During overcurrent, /OC asserts low after a 4–15ms deglitch delay; during thermal shutdown, /OC asserts immediately. In both cases, /OC remains low until the fault condition clears and the device recovers - requiring an external pull-up resistor (e.g., 100kΩ) for proper logic-level interfacing with microcontrollers.
Can PI5PD2069UEEX be used in battery-powered equipment with 3.3V input?
Yes. The device operates across 2.7V–5.5V, and its RDS(on) increases only modestly at 3.3V (75mΩ typ. vs. 70mΩ at 5V), maintaining <0.16V dropout at 2.1A. Combined with 0.1µA standby current and reverse-current blocking, it extends battery life in portable USB peripherals.
