Product details
Overview
PI5PD2065WE from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch designed for USB 5V rail switching in 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 input, and provides reverse current blocking with 1μA max standby supply current.
For engineers reviewing the PI5PD2065WE datasheet, PI5PD2065WE pinout, PI5PD2065WE application, or PI5PD2065WE equivalent, key selection criteria include its active-high enable logic, deglitched /OC fault reporting, thermal shutdown at 135°C with 10°C hysteresis, and SOIC-8 package compatibility with USB power integrity requirements.
Technical Context
The PI5PD2065WE integrates a charge-pump gate driver to fully enhance the internal N-channel MOSFET, enabling low RDS(on) (70mΩ @ 5V) while operating from a single 2.7–5.5V supply. Its control architecture includes under-voltage lockout (2.0–2.5V threshold), precise current-sense-based over-current detection, and automatic thermal shutdown recovery.
Unlike open-drain /EN variants (e.g., PI5PD2061), the PI5PD2065WE uses an active-high EN input compatible with standard CMOS/TTL logic. Fault signaling is via an open-drain /OC output with 4–15ms deglitch timing, asserted instantly during thermal shutdown and after delay during over-current events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70mΩ typ. @ 5V IN - ensures ≤75mV voltage drop at 1.5A, meeting USB 5V rail tolerance. |
| Continuous Current | 1.5A - supports full-power USB 2.0 downstream port operation or multi-port hub distribution. |
| Over-Current Threshold | 2.3A typ. - provides margin above 1.5A load while preventing nuisance tripping during inrush. |
| Rise Time | 0.6ms typ. - limits inrush di/dt to reduce EMI and stress on upstream capacitors. |
| Standby Supply Current | 1μA max - enables ultra-low quiescent power in battery-backed or always-on USB systems. |
| Thermal Shutdown | 135°C trip, 125°C recovery - protects against sustained short-circuit faults without latch-up. |
| Enable Logic | Active-high EN - simplifies interface with microcontroller GPIOs without level-shifting. |
Pinout & Package
PI5PD2065WE is housed in a lead-free, RoHS-compliant SOIC-8 (WE) package with exposed pad for enhanced thermal performance. Pin mapping is validated per Diodes Inc. PT0316-4 Rev. 4 (2013).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and thermal path to PCB; connects to exposed pad. |
| 2,3 | IN | Main 2.7–5.5V input supply; requires local 0.01–1μF ceramic bypass capacitor. |
| 4 | EN | Active-high enable input; drives internal gate driver when ≥2.7V applied. |
| 5 | /OC | Open-drain over-current/thermal fault indicator; requires external pull-up resistor (e.g., 100kΩ). |
| 6,7,8 | OUT | Switched 5V output; internally paralleled pins support 1.5A continuous current with low IR drop. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump gate drive | Enables full enhancement of N-MOSFET from 2.7V supply, eliminating need for external VBIAS. |
| Deglitched /OC output | 14ms minimum assertion delay prevents false triggering from transient surges or hot-plug noise. |
| Reverse current blocking | Prevents backflow from OUT to IN when disabled - critical for USB OTG and dual-power-domain systems. |
| No /OC glitch at power-up | Ensures clean fault reporting during system initialization without spurious interrupts to host controller. |
| UVLO with hysteresis | Turns off switch below ~2.0V and re-enables only above ~2.075V, avoiding oscillation near brown-out thresholds. |
Applications
| Laptop USB Hub Power Control | Desktop Motherboard USB Port Switching |
|---|---|

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 3-port USB 2.0 hub + power switches; no standalone /OC reporting; fixed 1.2A limit. | Requires full hub functionality; not suitable for discrete load-switch replacement. | Select only when consolidating hub logic and power control into one IC. |
| TPS2051BDBVR | 1.5A limit, 70mΩ RDS(on), but uses active-low /EN and lacks reverse current blocking. | Needs external reverse-blocking diode or FET; incompatible with EN-active-high control schemes. | Choose only if legacy /EN polarity matches existing firmware and board layout allows added diode. |
Compared with TUSB2036IRHBR and TPS2051BDBVR, the PI5PD2065WE uniquely combines active-high EN, reverse current blocking, and deglitched /OC in a SOIC-8 footprint-enabling direct replacement in USB host/hub designs without firmware or layout changes.

FAQ
What is the maximum allowable input voltage for PI5PD2065WE?
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 voltages below 2.7V may cause UVLO activation or reduced current capability due to increased RDS(on). The device is rated for USB 5V nominal rails with ±5% tolerance.
Does PI5PD2065WE require an external pull-up resistor on the /OC pin?
Yes, /OC is an open-drain output and requires an external pull-up resistor to a valid logic-high voltage (e.g., 3.3V or 5V). A 100kΩ resistor is recommended to minimize current draw while ensuring clean logic-level transitions. Without it, /OC cannot assert a valid high state during fault clearance.
How does thermal shutdown recovery work in PI5PD2065WE?
When junction temperature reaches 135°C, the device shuts down and holds /OC low. Recovery occurs automatically once the die cools to approximately 125°C (10°C hysteresis). During recovery, the switch cycles on/off until the fault is removed - providing visible indication of persistent overload without requiring external reset circuitry.
Can PI5PD2065WE be used in battery-powered USB devices?
Yes - its 1μA max standby supply current and 2.7V minimum operating voltage make it suitable for battery-powered USB peripherals. When disabled, it blocks reverse current flow from output to input, preserving battery charge. Verified operation down to 2.7V ensures compatibility with partially discharged Li-ion cells (3.0V nominal) and two-cell alkaline supplies.
