Product details
Overview
AP2411AMP-13 from Diodes Incorporated is a single-channel, current-limited, high-side power switch with active-high enable, 70 mΩ RDS(ON), 2.5 A accurate current limiting, and latch-off protection. It integrates output discharge, reverse current blocking, and 7 ms deglitch on the FLG pin, designed for USB-compliant hot-swap applications in laptops, docking stations, and set-top boxes.
For engineers reviewing the AP2411AMP-13 datasheet, AP2411AMP-13 pinout, AP2411AMP-13 application, or AP2411AMP-13 equivalent, key selection criteria include latch-off behavior under overcurrent, thermal shutdown at 140°C, SO-8EP package thermal resistance (92°C/W), and compatibility with 2.7–5.5 V input rails in space-constrained USB power delivery paths.
Technical Context
The AP2411AMP-13 implements an N-channel MOSFET-based high-side switch with integrated current-sense FET and thermal sensing circuitry. Its latch-off response triggers after a confirmed 7 ms deglitch window following overcurrent or overtemperature events, requiring EN toggle or power cycle to reset.
It features built-in soft-start (0.6 ms typical rise time), undervoltage lockout (2.0 V threshold with 50 mV hysteresis), and active-low open-drain FLG reporting with internal 25 Ω pull-down resistance. The device supports dual-purpose port use cases where controlled output discharge prevents residual voltage retention during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5 A typical; clamps load current to prevent damage during sustained overload or short-circuit conditions. |
| RDS(ON) | 70 mΩ at 5 VIN, +25°C; enables low conduction loss and minimal self-heating at 2 A continuous load. |
| Short-Circuit Response | 2 µs; detects and initiates current limiting before transient energy damages downstream components. |
| FLG Blanking Time | 7 ms typical; suppresses false fault reporting during capacitive inrush or momentary transients without external RC networks. |
| UVLO Threshold | 2.0 V rising; prevents switch turn-on until input rail stabilizes, ensuring safe hot-insertion in USB systems. |
| Thermal Shutdown | 140°C junction temperature; disables output and asserts FLG to protect against thermal runaway under sustained overload. |
| Input Voltage Range | 2.7 V to 5.5 V; matches standard USB 2.0/3.0 VBUS and portable system supply rails. |
| Output Discharge | Active when disabled; provides 105 Ω resistive path to discharge output capacitance below 0.5 V within 0.6 ms. |
Pinout & Package
AP2411AMP-13 uses the MSOP-8EP (exposed pad) package, optimized for thermal performance with 92°C/W junction-to-ambient resistance when mounted with recommended thermal vias to GND plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and logic; exposed pad must be connected to PCB GND plane for thermal management. |
| IN | Power input | Accepts 2.7–5.5 V supply; requires ≥0.1 µF ceramic bypass capacitor placed adjacent to pin. |
| EN | Enable control | Active-high logic input; toggling EN resets latch-off state after fault condition removal. |
| FLG | Fault reporting | Open-drain output asserted low after 7 ms deglitch upon overcurrent or overtemperature event. |
| OUT | Switched output | Delivers regulated power to load; all OUT pins must be externally tied together. |
| NC | No connection | Internally unconnected; recommended to tie to OUT for mechanical stability and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off overcurrent protection | Prevents repeated fault cycling by holding output off until EN toggle or power cycle-critical for system-level fault containment. |
| Integrated output discharge | Eliminates need for external bleed resistor; discharges output capacitance to <0.5 V in ≤0.6 ms when disabled. |
| Reverse current blocking | Blocks >0.01 µA leakage from VOUT to VIN when disabled, protecting upstream supplies in shared-bus architectures. |
| 7 ms deglitch on FLG | Rejects transient inrush spikes without external filtering-enables direct MCU GPIO monitoring of fault status. |
| Thermal shutdown with hysteresis | Shuts down at 140°C and re-enables only after cooling to ~120°C, preventing oscillation during marginal thermal conditions. |
Applications
| USB Hub Power Management | Laptop Docking Station Port Control |
|---|---|
|
Use Scenario: Individual USB port power switching in multi-port hubs with heavy capacitive loads. IC Role / Device Role / Timing Role: High-side power switch enabling/disabling VBUS per port with inrush current limiting and short-circuit latch-off. Use Value: Prevents bus-wide collapse during port short-circuit; 2 µs response isolates faults before host controller detects overcurrent. |
Use Scenario: Selective power delivery to peripherals (HDMI, Ethernet, USB-C) in compact laptop docks. IC Role / Device Role / Timing Role: Load switch managing 5 V rail distribution with thermal-aware shutdown and output discharge. Use Value: Enables clean hot-plug/unplug of peripherals; discharge function ensures no residual voltage remains on disconnected ports. |
| Set-Top Box USB Peripheral Interface | Residential Gateway Power Partitioning |
|
Use Scenario: Isolating USB-powered accessories (Wi-Fi adapters, storage drives) from main SoC power domain. IC Role / Device Role / Timing Role: Current-limited power gate with UVLO and reverse-blocking, activated via SoC GPIO. Use Value: Guarantees safe insertion/removal without affecting main system rail; 70 mΩ RDS(ON) minimizes voltage drop at 2 A. |
Use Scenario: Segmented 5 V distribution across multiple subsystems (Wi-Fi, Zigbee, PoE interface) in carrier-grade gateways. IC Role / Device Role / Timing Role: Independent power switch per subsystem with fault flag reporting to baseband processor. Use Value: Enables firmware-controlled power cutover during diagnostics; FLG signal allows real-time fault logging without polling. |
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 |
|---|---|---|---|
| AP2401AMP-13 | Active-low enable; identical RDS(ON), current limit, and thermal specs. | Requires inverted logic drive; suitable where system control logic is active-low by default. | Select when existing MCU GPIO or CPLD output is active-low and cannot be inverted in firmware. |
| TCK112G,LF | Lower RDS(ON) (45 mΩ), but no integrated output discharge; 1.2 A current limit. | Lacks latch-off and discharge-requires external circuitry for full USB compliance. | Choose only if lower conduction loss is critical and external discharge/FET reset logic can be added. |
Compared with AP2401AMP-13, the active-low variant shares identical protection and thermal behavior but demands inverted control signaling; compared with TCK112G,LF, AP2411AMP-13 delivers complete USB-ready functionality-including latch-off, discharge, and deglitched fault reporting-in a single chip without external components.

FAQ
What causes the AP2411AMP-13 to latch off, and how is it reset?
The AP2411AMP-13 latches off after detecting overcurrent or overtemperature for 7 ms (deglitch timeout). It remains off until the EN pin is toggled from high to low and back to high, or until VIN is cycled. This behavior prevents automatic re-engagement into a persistent fault condition and requires explicit system-level intervention.
Does the AP2411AMP-13 require external components for basic operation?
No external components are required for core functionality. A 0.1 µF ceramic capacitor between IN and GND is mandatory for stability. Output discharge, FLG deglitch, UVLO, and thermal shutdown are fully internal. Optional 120 µF output capacitance improves transient immunity in high-load applications.
How does the output discharge function behave during normal operation?
The discharge function activates only when EN is low (device disabled) or during power-up/power-down when VIN falls below UVLO. It provides a 105 Ω resistive path from OUT to GND, discharging output capacitance to <0.5 V in ≤0.6 ms. It is inactive during normal enabled operation.
Can AP2411AMP-13 be used in dual-purpose HDMI/MHL ports?
Yes-its fast short-circuit response (2 µs), latch-off behavior, and controlled discharge make it suitable for dual-purpose ports. However, ensure VIN ramps to operating voltage before enabling EN to avoid overstress on the discharge MOSFET when peripheral batteries are connected.
