Product details
Overview
PI5PD2065TAEX from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch designed for USB 5V rail control in host, hub, and peripheral applications. It delivers 1.5A continuous current, features accurate 2.3A typical over-current limiting, operates from 2.7V to 5.5V, and includes thermal shutdown, reverse current blocking, and deglitched /OC fault reporting - all in an SOIC-8 package.
For engineers reviewing the PI5PD2065TAEX datasheet, PI5PD2065TAEX pinout, PI5PD2065TAEX application, or PI5PD2065TAEX 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 UL recognition (E341484) for safety-critical USB power switching.
Technical Context
The PI5PD2065TAEX integrates a charge-pump gate driver to fully enhance its internal 70mΩ N-channel MOSFET at input voltages as low as 2.7V. Its over-current protection uses a current-sense circuit with 14ms deglitch timing and asserts an open-drain /OC signal only after confirmed fault conditions - eliminating false triggers during power-up or transient inrush.
Thermal protection activates at 135°C junction temperature with 10°C hysteresis, enabling automatic recovery once cooled to ~125°C. Under-voltage lockout disables the switch below ~2.0V input, ensuring controlled startup; reverse current blocking prevents backfeed when output voltage exceeds input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 70 mΩ typ. at 5V/3.3V - ensures ≤150mV drop at 1.5A, meeting USB voltage-drop compliance. |
| Current Limit | 2.3A typ. trip threshold - provides robust short-circuit protection while supporting peak loads beyond steady-state USB requirements. |
| Enable Logic | Active-high EN - simplifies interface with USB controller GPIOs without level-shifting or inversion. |
| Rise Time | 0.6ms typ. - balances inrush control and fast turn-on for hot-plug USB enumeration timing. |
| Supply Current (Standby) | ≤1μA max - enables ultra-low-power state retention in battery-backed or always-on USB hubs. |
| Operating Voltage | 2.7V to 5.5V - supports single-supply operation across 3.3V and 5V system rails, including brown-out tolerant designs. |
| Thermal Shutdown | 135°C activation with 10°C hysteresis - prevents permanent damage during sustained overload while allowing safe auto-recovery. |
Pinout & Package
PI5PD2065TAEX is housed in a RoHS-compliant, lead-free SOIC-8 package (JEDEC MS-012AC) with exposed pad for enhanced thermal dissipation (1200mW max power rating). Pin 1 is GND; pins 2–3 are IN (power input); pin 4 is EN (active-high enable); pin 5 is /OC (open-drain fault output); pins 6–8 are paralleled OUT terminals (power output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Primary return path for switch current and internal bias; connects to PCB ground plane for thermal and noise control. |
| IN (Pins 2, 3) | Power input | Dual-pin configuration reduces trace resistance and inductance; accepts 2.7–5.5V USB or system rail. |
| EN (Pin 4) | Enable control | CMOS/TTL-compatible active-high input; <0.8V = off, >2V = on; enables direct MCU GPIO drive. |
| /OC (Pin 5) | Fault indicator | Open-drain output asserted low during over-current or thermal shutdown; requires external pull-up (e.g., 100kΩ). |
| OUT (Pins 6, 7, 8) | Power output | Three paralleled pins minimize conduction loss and thermal stress; delivers switched 5V to downstream USB ports or peripherals. |
Key Features
| Feature | Design Value |
|---|---|
| Charge-pump gate drive | Enables full enhancement of N-MOSFET at 2.7V input - eliminates need for external P-MOSFET or higher-voltage bias rails. |
| Deglitched /OC reporting | 14ms fault confirmation window prevents false trips from capacitive inrush or ESD transients - improves system reliability. |
| Reverse current blocking | Prevents backfeed from output to input when disabled - critical for USB OTG, dual-role ports, and shared VBUS domains. |
| UL Recognition (E341484) | Validated for end-equipment safety compliance - reduces certification burden for USB host/hub OEMs. |
| Thermal cycling recovery | Auto-restarts after cooling to ~125°C - maintains fault visibility via /OC while preventing latch-up during intermittent shorts. |
Applications
| USB Host Port Switching | Self-Powered Hub Power Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power-switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IRHBR | Integrated USB 2.0 hub controller + power switches; no standalone switch mode; fixed 1.2A limit; no /OC reporting. | Requires full hub functionality - not suitable for discrete power gating where only switching and fault reporting are needed. | Select when consolidating hub logic and power control; avoid when needing independent switch control or precise 2.3A trip. |
| AP22653AW5-7 | 70mΩ RDS(on), 2.1A trip, active-high EN, but only SOT-23-5 (single OUT pin); 400mW power rating vs. SOIC-8's 1200mW. | Limited to lower-power applications (<1A continuous); insufficient thermal headroom for multi-port hub use. | Choose for space-constrained, single-port designs; reject for motherboard or multi-port hub deployments requiring SOIC-8 thermal performance. |
Compared with TUSB2036IRHBR and AP22653AW5-7, PI5PD2065TAEX uniquely combines SOIC-8 thermal capability, precise 2.3A current limiting, deglitched /OC reporting, and UL recognition - making it optimal for discrete, safety-certified, multi-port USB power distribution where control granularity and fault visibility are critical.

FAQ
What is the difference between PI5PD2065TAEX and PI5PD2061TAEX?
The PI5PD2065TAEX uses an active-high enable (/EN pin on PI5PD2061 is active-low), shares identical RDS(on), current limit, and protection features, and is pin-compatible in SOIC-8. Both are UL-recognized and functionally interchangeable in new designs where enable polarity aligns with system GPIO logic - no circuit changes required beyond EN signal polarity.
Does PI5PD2065TAEX require an external pull-up resistor on the /OC pin?
Yes - the /OC pin is open-drain and must be pulled up externally. A 100kΩ resistor to 3.3V or 5V is recommended per the datasheet; this sets fault-reporting voltage levels and minimizes standby current draw while ensuring clean logic-level transitions during over-current events.
Can PI5PD2065TAEX be used in USB-C applications?
Yes - as a discrete 5V VBUS switch, it supports USB-C downstream ports when paired with appropriate CC logic and protection ICs. Its 2.7–5.5V range, reverse current blocking, and 1.5A continuous rating meet USB-C 5V power delivery requirements for UFPs (Upstream Facing Ports), though it does not handle alternate modes or PD negotiation.
What is the maximum allowable ambient temperature for continuous 1.5A operation in SOIC-8?
At 1.5A and 5V input, RDS(on) ≈70mΩ yields ~157.5mW conduction loss. With SOIC-8 θJA ≈ 100°C/W (typ.), junction rise is ~15.8°C - allowing continuous operation up to +109°C ambient while staying within the 125°C max virtual junction temperature, assuming adequate PCB copper area for heat spreading.
