Product details
Overview
PI5PD2065UEE from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch designed for USB 5V bus-power management. It delivers 1.5A continuous current, features accurate 2.3A typical over-current limiting, operates from 2.7V to 5.5V input, and includes thermal shutdown, reverse current blocking, and deglitched /OC fault reporting - deployed in laptop motherboard USB hub power rails.
For engineers reviewing the PI5PD2065UEE datasheet, PI5PD2065UEE pinout, PI5PD2065UEE application, or PI5PD2065UEE equivalent, key selection criteria include its active-high enable logic (vs. PI5PD2061's active-low), 0.6ms typical rise time, 1μA standby supply current, and SOIC-8/EP-MSOP-8 package compatibility with USB hot-plug compliance requirements.
Technical Context
The PI5PD2065UEE integrates a charge-pump gate driver to fully enhance its internal N-channel MOSFET, enabling low RDS(on) (70mΩ @ 5V) without external bias. Its over-current protection uses current-sense feedback with 14ms deglitch timing before /OC assertion, while thermal shutdown activates at 135°C with 10°C hysteresis and automatic recovery.
Under-voltage lockout disables the switch below ~2.0V input, preventing erratic turn-on during power ramp-up. The /OC pin is open-drain with ≤0.4V low-level output at 5mA sink, requiring an external pull-up; no glitch occurs at power-up due to internal sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70mΩ @ 5V, 1.0A - meets USB voltage-drop spec (<250mV at 1.5A) |
| Continuous Current | 1.5A - supports dual-port USB hub power delivery |
| Over-Current Threshold | 2.3A typ. - precise trip point avoids nuisance shutdowns under transient loads |
| Rise Time | 0.6ms typ. - controls inrush current into 100µF downstream capacitance |
| Standby Supply Current | 1μA max - enables ultra-low-power suspend states in portable systems |
| Operating Voltage Range | 2.7V–5.5V - compatible with Li-ion battery backup (3.3V) and USB 5V rails |
| Thermal Shutdown | 135°C activation, 125°C recovery - protects against sustained short-circuit faults |
Pinout & Package
PI5PD2065UEE is packaged in SOIC-8 with exposed pad (EP-MSOP-8 footprint), optimized for thermal dissipation up to 1200mW. Pin numbering follows top-view orientation with GND on Pin 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power ground reference | Low-impedance return path for switch current and internal bias; connects to thermal pad |
| IN (Pins 2,3) | Input power rail | Accepts 2.7–5.5V supply; feeds charge pump and MOSFET source |
| EN (Pin 4) | Active-high enable control | Logic high ≥2V enables switch; low disables with <0.2μA leakage |
| /OC (Pin 5) | Open-drain fault indicator | Asserts low during over-current or thermal shutdown; requires external pull-up |
| OUT (Pins 6,7,8) | Switched output power | Delivers regulated 5V to downstream USB ports; supports reverse current blocking |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump gate drive | Enables full enhancement of N-MOSFET from 2.7V input - eliminates need for external P-MOSFET or level shifter |
| Deglitched /OC reporting | 14ms response delay prevents false triggers from capacitive load transients or ESD events |
| Reverse current blocking | Prevents backfeed from powered downstream devices into upstream supply during fault or disable |
| UVLO with hysteresis | Turns off below 2.0V with 75mV hysteresis - ensures clean power-up sequencing without oscillation |
| Thermal cycling recovery | Auto-restarts after cooling to 125°C - maintains system visibility of fault condition via persistent /OC low |
Applications
| USB Host Port Power Switching | Laptop Motherboard Hub Management |
|---|---|
|
Use Scenario: Controlling 5V power delivery to two downstream USB 2.0 ports on a notebook motherboard. IC Role / Device Role / Timing Role: High-side power switch with current limiting and fault reporting to USB controller.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IRHBR | Integrated USB 2.0 hub + power switches; 1.2A per port; no standalone /OC pin | Replaces discrete switch + controller; requires full USB protocol stack support | Choose when consolidating hub logic and power control - not for retrofitting existing switch-only designs |
| AP22653AW5-7 | 70mΩ RDS(on), 2.5A limit, 1.2μA standby, SOT-23-5 package | Smaller footprint but lower thermal capacity (400mW); no multi-pin OUT paralleling | Choose for space-constrained single-port applications where 1.5A continuous rating suffices |
Compared with TUSB2036IRHBR and AP22653AW5-7, the PI5PD2065UEE uniquely balances SOIC-8 thermal performance, active-high enable simplicity, and dedicated /OC signaling - making it optimal for discrete USB power rail control in resource-constrained embedded motherboards.

FAQ
What is the logic polarity of the EN pin on PI5PD2065UEE?
The EN pin on PI5PD2065UEE is active-high: applying ≥2.0V enables the internal MOSFET, while ≤0.8V disables it. This differs from the pin-compatible PI5PD2061, which uses active-low /EN. No external inversion is needed for microcontroller GPIO direct drive.
Does PI5PD2065UEE support reverse current blocking during disable?
Yes - the internal N-channel MOSFET architecture inherently blocks reverse current flow from OUT to IN when disabled. This prevents backfeeding from downstream devices (e.g., powered USB peripherals) into the upstream supply, satisfying USB specification isolation requirements.
How does the /OC pin behave during thermal shutdown versus over-current events?
/OC asserts low immediately during thermal shutdown, but delays 14ms before asserting during over-current events to reject transient spikes. In both cases, /OC remains low until the fault clears and the device recovers - providing unambiguous fault status to the system controller without requiring additional debouncing circuitry.
Can PI5PD2065UEE operate from a 3.3V input supply?
Yes - the device operates across 2.7V to 5.5V. At 3.3V input, RDS(on) increases to 75mΩ (typ.), still maintaining <250mV drop at 1.5A. Rise time slows to 0.4ms, and supply current remains <0.2μA in standby - making it viable for battery-backed 3.3V auxiliary rails.
