Product details

Overview

PI5PD2068UEE from Diodes Incorporated is a 70mΩ high-side N-channel MOSFET power-distribution switch optimized for USB 5V bus power control in self- and bus-powered hubs. It delivers 2.1A continuous current, features accurate 2.85A typical current limiting, thermal shutdown at 135°C, and reverse current blocking - enabling robust hot-plug protection in laptop motherboard and set-top box USB power rails.

For engineers reviewing the PI5PD2068UEE datasheet, PI5PD2068UEE pinout, PI5PD2068UEE application, or PI5PD2068UEE equivalent, key selection criteria include its 2.7–5.5V input range, 0.6ms typical rise time, deglitched /OC fault reporting, <1μA standby supply current, and EP-MSOP-8 package with exposed thermal pad tied to GND.

Technical Context

The PI5PD2068UEE integrates a charge-pump gate driver to fully enhance its internal 70mΩ N-channel MOSFET across the full 2.7–5.5V input range. Its constant-current limiting activates at 2.85A (typ.), entering foldback mode during sustained overloads while asserting an open-drain /OC signal after a 4–15ms deglitch window.

Thermal protection operates independently of current limit: junction temperature exceeding 135°C triggers immediate shutdown, with automatic recovery at ~125°C due to 10°C hysteresis. Under-voltage lockout disables the switch below ~2.0V on IN, preventing erratic turn-on during brownout conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
R_DS(on)	70 mΩ @ 5V/3.3V IN - ensures ≤105 mV voltage drop at 1.5A, meeting USB 5V rail drop requirements.
Continuous Current	2.1 A - supports full-power USB 2.0 downstream port operation (500 mA × 4 ports).
Current Limit Threshold	2.85 A (typ.) - provides margin above 2.1A max load while avoiding nuisance tripping under inrush.
Rise Time	0.6 ms (typ.) - limits inrush di/dt to protect upstream source and downstream capacitors.
Standby Supply Current	0.1 μA (typ.) - enables ultra-low-power disable state for battery-backed systems.
UVLO Threshold	2.0 V (min), 2.5 V (max) - guarantees clean startup only when stable 2.7V+ supply is present.
Thermal Shutdown	135 °C (trip), 125 °C (recovery) - prevents permanent damage during sustained short-circuit faults.

Pinout & Package

PI5PD2068UEE uses an 8-pin Exposed-Pad MSOP (EP-MSOP-8) package with thermal pad internally connected to GND. The exposed pad must be soldered to a PCB copper pour for effective heat dissipation and electrical grounding.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	Ground reference and thermal sink	Primary return path; connects internally to exposed pad for thermal conduction and noise reduction.
2,3 IN	Power input	Dual parallel input pins reduce trace resistance and inductance; accepts 2.7–5.5V USB-compatible supply.
4 /EN	Active-low enable	Logic low (≤0.8V) enables switch; high (≥2V) disables it - compatible with 3.3V/5V CMOS/TTL.
5 /OC	Open-drain fault indicator	Asserts low during overcurrent or thermal fault; requires external pull-up (e.g., 100kΩ) to V_IN.
6,7,8 OUT	Power output	Three parallel output pins minimize voltage drop and thermal stress under 2.1A load.

Key Features

Feature	Design Value
Built-in soft-start	Controls 0.6ms output ramp to limit inrush current into large downstream capacitance (e.g., 100µF).
Deglitched /OC reporting	14ms minimum assertion delay prevents false trips from transient overloads or ESD events.
Reverse current blocking	Prevents backflow from OUT to IN when disabled - critical for multi-rail USB hub isolation.
Charge-pump gate drive	Enables full enhancement of N-MOSFET at 2.7V IN, eliminating need for external high-side driver.
UL Recognition (E341484)	Validates safety compliance for end-equipment certification in consumer and industrial USB applications.

Applications

IC Role / Device Role / Timing Role: High-side current-limited power switch with fault reporting and thermal protection.

Use Value: Prevents system-wide brownout during simultaneous device insertion by limiting per-port current to 2.85A and isolating faults via /OC.

Use Scenario: Enabling/disabling USB host ports on a smart TV to comply with energy-saving standby modes.

IC Role / Device Role / Timing Role: Low-quiescent-power (0.1μA) enable-controlled power gate with reverse-blocking.

Use Value: Eliminates standby leakage from USB peripherals, reducing no-load power consumption below 5mW per port.

USB Self-Powered Hub Board

Industrial USB Peripheral Docking Station

Use Scenario: Distributing regulated 5V to six downstream ports in a desktop USB hub with local AC/DC supply.

IC Role / Device Role / Timing Role: Current-sensing, thermally protected distribution switch with UVLO and soft-start.

Use Value: Meets USB specification requirement for overcurrent reporting to host controller while sustaining 2.1A continuous per switch leg.

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; 120mΩ R_DS(on), no /OC reporting.	Replaces discrete switch + microcontroller logic; limited to USB hub topology only.	Select when full hub functionality (transceiver, PHY, repeater) is required alongside power control.
TPS2051BDBVR	2.2A rated, 95mΩ R_DS(on), 1.5ms rise time, no reverse blocking, SO-8 only.	Lacks reverse current blocking and thermal hysteresis; lower accuracy current limit (±25%).	Choose for cost-sensitive non-USB applications where reverse leakage is not critical and thermal cycling is infrequent.

Compared with TUSB2036IRHBR and TPS2051BDBVR, PI5PD2068UEE offers superior USB-specific optimization: tighter current limit accuracy (±15%), integrated reverse blocking, faster rise time, and EP-MSOP-8 thermal performance - making it optimal for space-constrained, high-reliability USB power distribution.

FAQ

What is the function of the /OC pin, and how should it be interfaced?

The /OC pin is an open-drain output that asserts low during overcurrent or thermal shutdown events. It requires an external pull-up resistor to V_IN; a 100kΩ resistor is recommended to minimize quiescent current while ensuring reliable logic-level detection by a microcontroller GPIO or USB controller interrupt pin. The /OC remains latched low until the fault condition clears and the device recovers.

Does PI5PD2068UEE support reverse current blocking, and under what conditions?

Yes - PI5PD2068UEE blocks reverse current flow from OUT to IN when disabled (/EN high), due to its N-channel high-side architecture and integrated body-diode control. This occurs automatically with no external components required and is verified across the full operating temperature range (-40°C to +105°C) and input voltage range (2.7–5.5V).

How does the thermal shutdown recover, and is manual reset needed?

Recovery is fully automatic: once the junction temperature falls below ~125°C (10°C hysteresis below 135°C trip point), the device re-enables the power switch without external intervention. No /EN toggling or power cycle is required - the switch cycles on/off autonomously during persistent overload until the fault is removed.

Can PI5PD2068UEE be used with 3.3V input supplies, and how does R_DS(on) change?

Yes - it operates across 2.7–5.5V. At 3.3V IN, R_DS(on) increases to 75 mΩ (typ.), still maintaining <160 mV drop at 2.1A. This is within USB voltage-drop specifications and confirmed by characterization data across temperature, ensuring reliable operation in dual-rail (3.3V/5V) embedded systems.
