Product details
Overview
AP2411FGE-7 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, integrated output discharge, and latched-off over-current protection. Used in USB ports of laptops and docking stations to manage inrush and prevent bus faults.
For engineers reviewing the AP2411FGE-7 datasheet, AP2411FGE-7 pinout, AP2411FGE-7 application, or AP2411FGE-7 equivalent, key selection criteria include enable polarity (active-high), latch-off behavior under OCP, thermal shutdown threshold (140°C), UVLO (2.0V typ), and U-DFN3030-8 package thermal performance (θJA = 84°C/W).
Technical Context
The AP2411FGE-7 integrates an N-channel MOSFET with precision current-sense circuitry and deglitch logic to enforce 2.5A ±0.45A current limiting. Its internal discharge FET activates upon disable, providing 100Ω resistive path to discharge output capacitance in ≤0.6ms.
It implements dual-protection hierarchy: fast 2µs short-circuit detection triggers current limiting, followed by 7ms deglitch timeout before latching off; thermal shutdown activates at 140°C with 20°C hysteresis, asserting FLG and disabling output until reset via EN toggle or power cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 2.0A max - supports USB 2.0/3.0 downstream port power delivery without derating at +25°C ambient. |
| RDS(ON) | 70mΩ typ at VIN=5V - minimizes conduction loss (≤0.7W at 2A), enabling compact thermal design in U-DFN3030-8. |
| Current Limit Threshold | 2.5A typ - clamps fault current during short-circuit, limiting I²t stress on PCB traces and upstream supply. |
| Short-Circuit Response Time | 2µs - detects and initiates current limiting before energy dissipation damages internal FET or external components. |
| UVLO Threshold | 2.0V rising - prevents erratic switching during brown-out or hot-plug insertion when input rail is unstable. |
| Thermal Shutdown | 140°C junction - protects against sustained overload; 20°C hysteresis ensures stable re-enable only after sufficient cooling. |
| Output Discharge Time | 0.6ms to <0.5V - safely drains 1µF output cap, eliminating residual voltage that could cause backfeed or ESD risk during hot removal. |
Pinout & Package
AP2411FGE-7 is housed in a 3.0mm × 3.0mm × 0.55mm U-DFN3030-8 package with exposed thermal pad (EP), rated θJA = 84°C/W when mounted with recommended thermal vias to GND plane. Pin 1 is FLG; pins 2–3 are IN; pin 4 is EN; pins 5–6 are OUT; pin 7 is NC; pin 8 is GND. Exposed pad must be soldered to PCB GND for thermal integrity but not used as primary current return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FLG (Pin 1) | Open-drain fault indicator | Active-low signal asserted after 7ms deglitch on OCP or OTP; requires external pull-up; blanked for 7ms post-enable. |
| IN (Pins 2,3) | Power input | Must be decoupled with ≥0.1µF ceramic capacitor; both pins tied together externally; supports 2.7–5.5V input range. |
| EN (Pin 4) | Enable control | Active-high logic input; VIH ≥2V, VIL ≤0.8V; enables internal driver and discharge FET when high. |
| OUT (Pins 5,6) | Switched output | Drives load; both pins tied together externally; reverse current blocking prevents backfeed when disabled. |
| NC (Pin 7) | No internal connection | Not bonded; recommended to tie to OUT for mechanical stability and EMI reduction. |
| GND (Pin 8) | Ground reference | Primary return path for sense circuitry and power FET; connects to EP for thermal conduction. |
| EP (Exposed Pad) | Thermal interface | Must be soldered to ≥1cm² GND copper area with ≥4 thermal vias; improves θJA by ~20°C/W vs. no EP connection. |
Key Features
| Feature | Design Value |
|---|---|
| Latched-off over-current protection | Prevents repeated fault cycling: device remains off after 7ms deglitch unless EN is toggled or VIN cycled - critical for system-level fault containment. |
| Integrated output discharge | 100Ω internal discharge path reduces VOUT to <0.5V in ≤0.6ms - eliminates need for external bleed resistor and associated BOM cost/PCB space. |
| 7ms FLG deglitch | Rejects transient inrush spikes (e.g., from 120µF load caps) without false fault reporting - removes requirement for external RC filter on FLG line. |
| Reverse current blocking | Prevents backflow from loaded OUT to IN when disabled - essential for multi-rail systems and USB OTG where VBUS may be present without host power. |
| Built-in soft-start | 0.6ms typical rise time limits dV/dt-induced EMI and inrush current - avoids tripping upstream fuses or causing supply droop in shared rails. |
Applications
| USB 3.0 Downstream Port | Laptop Docking Station |

IC Role / Device Role / Timing Role: Robust front-end switch protecting against field wiring errors (e.g., accidental VBUS-to-GND shorts). Use Value: 70mΩ RDS(ON) sustains 2A with <100mW conduction loss - reduces thermal load in sealed enclosures without forced air. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2401FGE-7 | Identical specs except active-low enable (EN low = ON); same latch-off, RDS(ON), and protection features. | Requires inverted logic drive; unsuitable if host MCU GPIO is open-drain or lacks active-low control capability. | Select when system control logic natively supports active-low enable or uses pull-down configuration. |
| TCK112G,LF | 2.5A current limit, 60mΩ RDS(ON), but no integrated discharge FET; FLG has no deglitch; thermal shutdown at 150°C. | Lacks output discharge - requires external resistor/capacitor network to meet USB hot-unplug requirements. | Choose only if discharge function is handled elsewhere in design and tighter RDS(ON) justifies added external components. |
Compared with AP2401FGE-7, AP2411FGE-7 offers native compatibility with standard GPIO high-drive logic, while TCK112G,LF trades discharge integration for lower on-resistance but increases BOM count and layout complexity.

FAQ
What happens after AP2411FGE-7 latches off due to over-current?
Once latched off, the device remains disabled until either the EN pin is toggled (high→low→high) or VIN is cycled (power removed and reapplied). The FLG pin stays low during latch-off, signaling persistent fault. No automatic recovery occurs - this ensures system-level fault containment and prevents repeated stress on faulty loads.
Can AP2411FGE-7 drive a 120µF output capacitor without false triggering?
Yes. Its 7ms deglitch on the FLG pin filters transient inrush currents from large capacitors like 120µF. During enable, FLG is blanked for 7ms, and subsequent over-current events require sustained violation beyond 7ms to assert fault - preventing nuisance trips during normal hot-plug events.
Is the exposed pad of AP2411FGE-7 electrically connected to GND?
No. The exposed pad is thermally connected to the die substrate but is not electrically bonded to any internal node. It must be soldered to the PCB's GND plane solely for heat dissipation. Using it as a current-carrying ground path violates the thermal design intent and risks reliability degradation.
How does AP2411FGE-7 handle reverse current when disabled?
It blocks reverse current flow from OUT to IN using its internal N-MOSFET architecture and gate control logic. When disabled (EN low), the power FET is fully turned off, achieving <1µA reverse leakage (IREV) at VOUT = 5V and VIN = 0V - meeting USB specification requirements for backfeed prevention.
