Product details
Overview
AP2411AS-13 from Diodes Incorporated is a single-channel, current-limited high-side power switch with active-high enable, designed for USB and hot-swap applications. It delivers 2.0A continuous load current, features 70mΩ RDS(ON) at 5V, 2µs short-circuit response time, integrated output discharge, and latched-off overcurrent protection. It operates across 2.7V–5.5V input range and is qualified for LCD TVs, docking stations, and USB-powered peripherals.
For engineers reviewing the AP2411AS-13 datasheet, AP2411AS-13 pinout, AP2411AS-13 application, or AP2411AS-13 equivalent, this page provides verified functional role (USB-compliant high-side switch), latch-off OCP behavior, thermal shutdown threshold (140°C), FLG deglitch timing (7ms), and package-specific thermal resistance (96°C/W for SO-8) - all critical for robust hot-swap design validation.
Technical Context
The AP2411AS-13 implements a N-channel MOSFET high-side switch with integrated current-sense FET and thermal sensing circuitry. Its control logic enables immediate current limiting upon overload detection, followed by 7ms deglitch before latching off - eliminating external timing components. The device combines UVLO (2.0V turn-on threshold), reverse current blocking, and soft-start (0.6ms typical rise time) in a single die.
It uses an open-drain FLG output with built-in 7ms blanking to suppress false fault reporting during capacitive load transients. Discharge function activates automatically on disable, providing 105Ω resistive path to ground for controlled VOUT decay. Thermal protection cycles the switch at ~140°C trip with 20°C hysteresis, independent of EN state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 2.0A - supports full USB 2.0/3.0 bus-powered peripheral loads without derating at +25°C. |
| RDS(ON) | 70mΩ max @ 5V - minimizes conduction loss (≤70mW at 1A), enabling compact thermal design in SO-8. |
| Short-Circuit Response Time | 2µs - limits energy delivered during fault, protecting downstream components and PCB traces. |
| Current Limit Threshold | 2.5A typ - accurately clamps output during overload while allowing brief inrush surges up to 2.5A. |
| FLG Blanking Time | 7ms typ - suppresses false fault assertions from capacitive load turn-on transients without external RC. |
| UVLO Threshold | 2.0V rising - prevents erratic switching during brown-out or hot-plug ramp-up, ensuring clean power sequencing. |
| Thermal Shutdown | 140°C - protects internal MOSFET under sustained overload; hysteresis ensures stable recovery at 120°C. |
Pinout & Package
AP2411AS-13 is supplied in SO-8 package with exposed pad (non-electrical, for thermal enhancement). Pin 1 = GND, Pins 2–3 = IN (tied externally), Pin 4 = EN (active-high), Pin 5 = FLG (open-drain), Pins 6–7 = OUT (tied externally), Pin 8 = NC (recommended tied to OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power Ground Reference | Primary return path for IN, OUT, and internal bias; must connect to low-impedance PCB ground plane. |
| IN (Pins 2,3) | Input Voltage Supply | High-current input node; requires ≥0.1µF ceramic capacitor placed adjacent to pins to suppress supply noise. |
| EN (Pin 4) | Enable Control Input | Active-high logic interface; drives internal driver only when voltage ≥2V (VIH min); 0.1µA leakage ensures low standby current. |
| FLG (Pin 5) | Fault Reporting Output | Open-drain signal asserted low after 7ms deglitch on OCP or OTP; requires external pull-up for system monitoring. |
| OUT (Pins 6,7) | Switched Output Node | Delivers regulated power to load; pins must be shorted externally to share current and reduce inductance. |
| NC (Pin 8) | No Internal Connection | Not bonded; recommended tied to OUT to minimize EMI and improve thermal coupling to output copper. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 105Ω discharge path activated on disable - eliminates residual VOUT without external FET or resistor. |
| Latched-Off Overcurrent Protection | Automatic 7ms deglitch then hard latch-off - prevents repeated fault cycling, simplifying host firmware fault handling. |
| Reverse Current Blocking | Active MOSFET body diode isolation - blocks backfeed from VOUT to VIN when disabled, critical for dual-port USB/MHL designs. |
| Built-in Soft-Start | 0.6ms typical rise time - controls inrush into heavy capacitive loads (e.g., 120µF USB ports), avoiding input rail collapse. |
| Thermal Protection with Hysteresis | 140°C trip / 120°C recovery - enables safe auto-recovery under intermittent overload without system reset. |
Applications
| USB 3.0 Hub Power Switching | Docking Station Load Management |
|---|---|
|
Use Scenario: Power delivery to four downstream USB 3.0 ports with individual overcurrent protection and hot-plug capability. IC Role / Device Role / Timing Role: High-side power switch controlling VBUS per port; enables/disables via host GPIO with active-high EN; FLG reports per-port fault.

Use Scenario: Powering USB peripherals (keyboard/mouse/storage) from residential gateway set-top boxes with limited thermal budget. IC Role / Device Role / Timing Role: Single-channel load switch managing 2A peak load; thermal shutdown (140°C) prevents overheating in enclosed plastic enclosures. Use Value: Eliminates need for discrete thermal sensor and comparator; SO-8 package fits standard 12mm × 6mm footprint with no layout redesign. |
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 |
|---|---|---|---|
| AP2401AS-13 | Active-low EN instead of active-high; identical electrical specs, pinout, and protection features. | Requires inverted logic drive from host MCU; otherwise drop-in compatible in SO-8 layout. | Select when system control logic natively supports active-low enable signals to avoid level-shifter. |
| TCK127G,LF | Lower RDS(ON) (45mΩ), higher ICONT (3.0A), but no integrated discharge function and 10ms deglitch. | Supports higher current loads but requires external discharge FET and RC network for same functionality. | Choose for >2.5A applications where board space allows added components and thermal margin exceeds 96°C/W. |
Compared with AP2411AS-13, AP2401AS-13 offers identical protection and performance with inverted enable polarity - ideal for legacy control logic - while TCK127G provides higher current capacity at the cost of added BOM complexity and loss of integrated discharge.

FAQ
What is the purpose of the NC pin (Pin 8) on AP2411AS-13?
Pin 8 is not internally connected and serves no electrical function. Diodes Incorporated recommends tying it to the OUT net to improve thermal coupling to the output copper pour and reduce electromagnetic interference from floating metal. This connection does not affect switching behavior or protection functionality.
Does AP2411AS-13 require an external pull-up resistor on the FLG pin?
Yes - FLG is an open-drain output and requires an external pull-up resistor (typically 10kΩ to 5V or 3.3V) to generate a valid logic-high signal when no fault is present. Without it, FLG remains floating and cannot reliably indicate normal operation or fault conditions to the host microcontroller.
How does the output discharge function behave during normal operation?
The discharge function activates only when the device is disabled (EN low) or during power-up/power-down when VIN falls below UVLO (2.0V). It does not operate while the switch is enabled, ensuring uninterrupted power delivery. Discharge terminates automatically once VOUT drops below 0.5V or EN is reasserted.
Can AP2411AS-13 be used with input voltages below 2.7V?
No - the absolute minimum operating VIN is 2.7V per Recommended Operating Conditions. Below this, UVLO holds the switch off, and key parameters like RDS(ON), current limit accuracy, and rise time are not guaranteed. Operation at 2.5V may result in unpredictable turn-on behavior or failure to latch off during overcurrent.
