Product details
Overview
PI5PD2069WE+CX from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch optimized for USB bus- and self-powered applications, delivering 2.1A continuous current, 2.85A typical current-limit threshold, 2.7V–5.5V input range, and reverse-current blocking - deployed in laptop motherboard USB port power control.
For engineers reviewing the PI5PD2069WE+CX datasheet, PI5PD2069WE+CX pinout, PI5PD2069WE+CX application, or PI5PD2069WE+CX equivalent, key selection criteria include enable polarity (active-high EN), /OC open-drain fault reporting with 4–15ms deglitch, thermal shutdown at 135°C with 10°C hysteresis, and SOIC-8 package compatibility with USB 2.0 hot-swap compliance.
Technical Context
The PI5PD2069WE+CX integrates a charge-pump gate driver to fully enhance its internal 70mΩ N-channel MOSFET across the full 2.7V–5.5V supply range, enabling robust high-side switching without external bias. Its constant-current limiting engages at 2.85A (typ.), entering foldback mode during sustained overloads.
Thermal protection activates at 135°C junction temperature and recovers automatically at ~125°C, while under-voltage lockout disables the switch below ~2.0V input and provides 75mV hysteresis. The /OC pin asserts low on overcurrent or thermal fault, with no glitch at power-up and built-in deglitching (4–15ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70 mΩ typ. at 5V/3.3V - ensures ≤210 mV drop at 3A, meeting USB voltage-drop spec |
| Continuous Current | 2.1 A - supports full-power USB 2.0 downstream port operation |
| Current Limit Threshold | 2.85 A typ. - precise foldback limit prevents false trips under transient inrush |
| Enable Polarity | Active-high EN - compatible with standard logic-level microcontroller GPIOs |
| /OC Response Delay | 4–15 ms deglitched - suppresses noise-induced false fault reporting |
| Standby Supply Current | 0.1 µA max - enables ultra-low-power suspend states in portable systems |
| UVLO Threshold | 2.0 V min with 75 mV hysteresis - guarantees clean turn-on after brownout recovery |
Pinout & Package
PI5PD2069WE+CX uses a lead-free, green SOIC-8 (WE) package with exposed thermal pad internally connected to GND. Pin 1 is GND; pins 2–3 are parallel IN inputs; pin 4 is active-high EN; pin 5 is open-drain /OC; pins 6–8 are paralleled OUT outputs; Power PAD is soldered to PCB ground plane for thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference and thermal sink | Primary return path; connects to Power PAD for enhanced heat transfer |
| 2,3 IN | Power input supply | Parallel inputs accept 2.7–5.5V; bypass capacitor required near pins |
| 4 EN | Logic enable input (active-high) | Drives internal charge pump; <0.8V = off, >2V = on |
| 5 /OC | Open-drain fault indicator | Pulled low during overcurrent or thermal fault; requires external pull-up |
| 6,7,8 OUT | Switched power output | Paralleled outputs deliver up to 2.1A; connect to USB VBUS or load rail |
Key Features
| Feature | Design Value |
|---|---|
| Built-in soft-start | 0.6 ms typical rise time - limits inrush current into capacitive USB loads |
| Reverse current blocking | Prevents backflow from OUT to IN when disabled - eliminates need for external diode |
| Charge-pump gate drive | Enables full enhancement of N-MOSFET at 2.7V input - avoids P-MOSFET RDS(on) penalty |
| No /OC glitch at power-up | Ensures clean enumeration in USB host controllers - avoids spurious overcurrent interrupts |
| UL Recognized (E341484) | Validated for safety-critical end equipment including consumer and industrial USB hubs |
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 |
|---|---|---|---|
| TUSB2036IRHBR | Integrated USB 2.0 hub controller + power switches; 3 downstream ports; fixed 100mA/500mA per port | Requires full hub functionality - not a standalone switch | Select only if replacing entire hub IC; not suitable for discrete load-switch replacement |
| AP22653AW-7 | 2.1A switch with 42mΩ RDS(on), active-high EN, but no UL recognition or /OC deglitching | Lacks fault-reporting robustness for certified USB products | Use where cost sensitivity outweighs safety certification or noise immunity requirements |
Compared with TUSB2036IRHBR and AP22653AW-7, PI5PD2069WE+CX uniquely combines UL recognition, precise 2.85A current limiting with deglitched /OC, and SOIC-8 footprint - making it optimal for certified, discrete USB power-switching in host and hub designs.

FAQ
What is the enable logic polarity of PI5PD2069WE+CX?
The PI5PD2069WE+CX features active-high EN: the internal MOSFET turns on when EN ≥ 2.0 V and turns off when EN ≤ 0.8 V. This differs from the pin-compatible PI5PD2068WE+CX, which uses active-low /EN. Confirm logic level compatibility with host MCU GPIO before layout.
Does PI5PD2069WE+CX require an external pull-up on the /OC pin?
Yes - the /OC pin is open-drain and must be pulled up externally. A 100 kΩ resistor to VCC is recommended per the datasheet to minimize standby current while ensuring fast logic-level transitions during fault events.
How does thermal shutdown recover after activation?
Recovery is fully automatic: once the junction temperature falls to ~125°C (10°C below the 135°C trip point), the device re-enables. It will cycle on/off under persistent overload until the fault is removed - providing fail-safe operation without external reset circuitry.
Can PI5PD2069WE+CX be used in USB 3.0 applications?
No - PI5PD2069WE+CX is specified and validated for USB 2.0 (480 Mbps) power delivery only. Its current-limit accuracy, timing, and fault response meet USB 2.0 specifications but lack characterization or qualification for USB 3.x SuperSpeed signaling or higher current profiles.
