Product details
Overview
PI5PD2061WEX from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch designed for USB host and hub applications. It delivers 1.5A continuous current, features accurate 2.3A typical over-current limiting, operates from 2.7V to 5.5V, and provides reverse current blocking, thermal shutdown at 135°C, and deglitched /OC fault reporting - enabling robust hot-plug power control in laptop motherboards and USB peripherals.
For engineers reviewing the PI5PD2061WEX datasheet, PI5PD2061WEX pinout, PI5PD2061WEX application, or PI5PD2061WEX equivalent, key selection criteria include its 70mΩ RDS(on) at 5V, 0.6ms typical rise time, 1μA standby supply current, active-low enable (/EN), and SOIC-8 package with validated thermal performance up to 125°C junction temperature.
Technical Context
The PI5PD2061WEX integrates a charge-pump gate driver to fully enhance its internal N-channel MOSFET, eliminating need for external biasing while maintaining low RDS(on) across 2.7–5.5V input range. Its over-current protection uses current-sense feedback with 14ms deglitch timing, and thermal shutdown activates only under sustained overload - not ambient temperature alone.
Under-voltage lockout (UVLO) holds the switch off until IN exceeds ~2.0V with 75mV hysteresis, ensuring clean power-up behavior. The open-drain /OC output asserts low during over-current or thermal fault, requiring an external pull-up resistor (e.g., 100kΩ), and remains latched until fault removal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70 mΩ typ. at 5V/1A - meets USB voltage-drop spec; enables ≤75mV drop at 1.5A load. |
| Continuous Current | 1.5 A - supports full-power USB 2.0 downstream port or multi-port hub power rail. |
| Over-Current Threshold | 2.3 A typ. - precise trip point avoids nuisance shutdowns while protecting cables and connectors. |
| Enable Logic | Active-low /EN - compatible with standard USB controller GPIOs without level-shifting. |
| Rise Time | 0.6 ms typ. - controls inrush current into large output capacitors (e.g., 100µF). |
| Standby Supply Current | 0.2 µA max. at −40°C to +125°C - enables ultra-low-power suspend states in battery-powered systems. |
| Thermal Shutdown | 135°C trip, 125°C recovery - hysteresis prevents oscillation during marginal overload conditions. |
Pinout & Package
PI5PD2061WEX is packaged in RoHS-compliant, lead-free SOIC-8 (JEDEC MS-012AA) with exposed pad for enhanced thermal dissipation (θJA = 60°C/W). Pin 1 is GND; pins 6–8 are paralleled OUT terminals for low-inductance, high-current output routing.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power and signal reference ground; connects to PCB thermal pad for heat sinking. |
| 2 | IN | Main power input (2.7–5.5V); requires local 0.01–1µF ceramic bypass capacitor. |
| 3 | /EN | Active-low enable: logic low turns on switch; high-Z when disabled, drawing <1µA. |
| 4 | /OC | Open-drain fault indicator: pulled low during over-current or thermal shutdown. |
| 5 | OUT | Primary power output; pins 6–8 are bonded in parallel to reduce resistance and inductance. |
| 6–8 | OUT | Secondary output terminals - electrically tied internally; used for high-current PCB trace routing. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse Current Blocking | Prevents backflow from output to input when disabled - eliminates need for external blocking diode in USB VBUS paths. |
| Deglitched /OC Output | 14ms fault assertion delay filters transient spikes; avoids false reports during hot-plug insertion or load switching. |
| Charge-Pump Gate Drive | Enables full enhancement of N-MOSFET from 2.7V input - achieves low RDS(on) without external VGS boost. |
| UVLO with Hysteresis | Turns off switch below ~2.0V and re-enables only above ~2.075V - prevents erratic operation during brown-out. |
| Thermal Cycling Recovery | Auto-restarts after cooling by ≥10°C - maintains system availability during intermittent overload without manual reset. |
Applications
| USB Host Port Power Switch | Laptop Motherboard VBUS Control |
|---|---|
Use Scenario: Power delivery to downstream USB 2.0 ports on desktop motherboard or docking station. IC Role / Device Role / Timing Role: High-side power switch with current limiting and fault reporting for USB VBUS rail. Use Value: Enables compliance with USB specification's 500mA per-port limit and hot-plug safety requirements. |
Use Scenario: Dynamic VBUS enable/disable in thin-and-light notebooks during sleep/wake transitions. IC Role / Device Role / Timing Role: Low-quiescent-current power gate controlling USB-C or legacy USB-A VBUS. Use Value: Reduces system standby power by cutting VBUS leakage; 0.2µA disable current extends battery life. |
| Self-Powered USB Hub | Set-Top Box Peripheral Port |
Use Scenario: Independent power switching for each downstream port in a 4-port self-powered hub. IC Role / Device Role / Timing Role: Per-port current-limited distribution switch with individual /OC reporting. Use Value: Isolates faults to single port without disabling entire hub - improves system reliability and diagnostics. |
Use Scenario: USB peripheral power management in consumer STB with HDMI-CEC and OTG support. IC Role / Device Role / Timing Role: Robust 5V rail switch handling mixed loads (keyboard, storage, dongles). Use Value: Withstands 1.5A continuous + 2.3A surge - accommodates USB flash drives and Wi-Fi adapters simultaneously. |
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 |
|---|---|---|---|
| TUSB2036IPWR | Integrated USB 2.0 hub controller + power switches; 1.5A per port, but fixed 5V-only operation. | Requires full USB protocol stack; not suitable as standalone power switch. | Choose only if USB hub functionality (PHY, transceiver, packet routing) is also needed. |
| AP22653AW5-7 | 70mΩ RDS(on), 2.1A current limit, active-high EN, no /OC output. | Lacks fault reporting and deglitching - unsuitable where USB controller needs over-current status. | Select when simplified enable control suffices and fault visibility is handled externally. |
Compared with TUSB2036IPWR and AP22653AW5-7, PI5PD2061WEX uniquely combines standalone high-side switching, precise 2.3A current limiting, deglitched /OC reporting, and USB-optimized 70mΩ RDS(on) - making it optimal for discrete VBUS control where protocol intelligence resides elsewhere.

FAQ
What is the maximum allowable input voltage for PI5PD2061WEX?
The absolute maximum input voltage is +6V, but the recommended operating range is 2.7V to 5.5V. Operation above 5.5V risks permanent damage, and UVLO ensures safe turn-on only above ~2.0V. All voltage ratings are referenced to GND, and exceeding ±0.3V on any pin relative to GND violates absolute maximum ratings.
Does PI5PD2061WEX support reverse current blocking during disable?
Yes - the internal N-channel MOSFET architecture and integrated body-diode control circuitry actively block reverse current flow from OUT to IN when the device is disabled. This eliminates the need for an external Schottky diode in USB VBUS paths and prevents backfeeding into upstream supplies during hot-unplug events.
How does the /OC pin behave during thermal shutdown versus over-current events?
During over-current, /OC asserts low after a 14ms deglitch delay; during thermal shutdown, it asserts immediately. In both cases, /OC remains low until the fault condition clears and the device recovers - either via current reduction (over-current) or die cooling by ≥10°C (thermal). An external 100kΩ pull-up is required for proper logic-level signaling.
Can PI5PD2061WEX be used in battery-powered equipment with 3.3V supply?
Yes - it operates down to 2.7V input and delivers 1.5A continuous current at 3.3V, with RDS(on) rising to 75mΩ (typ.) at that voltage. Its 0.2µA max standby current at full temperature range makes it ideal for battery-critical designs, and reverse blocking preserves battery charge during system sleep.
