Product details
Overview
AP2411ASN-7 from Diodes Incorporated is a single-channel, current-limited, high-side power switch optimized for USB and hot-swap applications. It features active-high enable, 2.5A accurate current limiting, 70mΩ typical RDS(ON) at 5V, 2µs short-circuit response time, and integrated output discharge. It operates from 2.7V to 5.5V input and latches off after overcurrent detection with 7ms deglitch.
For engineers reviewing the AP2411ASN-7 datasheet, AP2411ASN-7 pinout, AP2411ASN-7 application, or AP2411ASN-7 equivalent, key selection criteria include latch-off behavior under fault, thermal shutdown threshold (140°C), UVLO (2.0V typ), FLG open-drain reporting with blanking, and compatibility with heavy capacitive loads in USB-powered peripherals.
Technical Context
The AP2411ASN-7 implements an N-channel MOSFET high-side switch with internal current-sense FET architecture-eliminating external sense resistors while maintaining low conduction loss. Its protection logic combines fast 2µs short-circuit detection, 7ms deglitch filtering on FLG, and thermal shutdown at 140°C with 20°C hysteresis.
It integrates soft-start (0.6ms typical rise time), undervoltage lockout (2.0V rising threshold), reverse current blocking, and a dedicated discharge path (RDIS = 105Ω) activated only when disabled-enabling controlled VOUT decay without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical; clamps load current during overload to prevent damage to downstream circuitry |
| RDS(ON) | 70mΩ max at 25°C, 5V IN; enables low-power-loss switching for 2A continuous loads |
| Short-Circuit Response | 2µs; ensures rapid current limiting before energy dissipation causes thermal stress |
| UVLO Threshold | 2.0V rising; prevents erratic turn-on during brown-out or hot-plug ramp-up |
| FLG Blanking Time | 7ms typical; suppresses false fault reports from inrush or transient capacitive loading |
| Discharge Resistance | 105Ω; provides controlled VOUT decay to <0.5V in ≤0.6ms when disabled |
| Thermal Shutdown | 140°C junction; latches off until temperature drops 20°C below threshold or EN cycled |
Pinout & Package
AP2411ASN-7 is housed in a U-DFN2020-6 package (2.0mm × 2.0mm, 0.5mm height, exposed thermal pad). The package supports high-density PCB layouts and enhanced thermal performance via soldered exposed pad connected to GND plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; must be low-impedance connection to PCB ground plane |
| IN | Input voltage supply | Accepts 2.7–5.5V; requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin |
| EN | Enable control | Active-high logic input; toggling resets latch-off state after fault condition clears |
| FLG | Fault reporting | Open-drain, active-low output; asserts after 7ms deglitch upon overcurrent or overtemperature |
| OUT | Switched output | Delivers regulated power to load; all OUT pins internally tied together |
| NC | No internal connection | Not bonded; recommended to tie externally to OUT for mechanical stability and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off overcurrent protection | Prevents repeated fault cycling by holding OFF until EN toggle or power cycle-critical for system-level fault containment |
| Integrated output discharge | 105Ω internal discharge path eliminates need for external bleed resistor, reducing BOM count and board space |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled-essential for dual-power-domain isolation in USB OTG and shared-port designs |
| 7ms FLG deglitch | Hardware-filtered fault reporting avoids false triggers from capacitive inrush, enabling robust operation without external RC networks |
| Soft-start with 0.6ms rise time | Controls dV/dt at turn-on to limit inrush current into large output capacitance-prevents input rail collapse and connector arcing |
Applications
| USB 3.0 Hub Power Management | Laptop Docking Station Port Control |
|---|---|
Use Scenario: Individual port power control in multi-port USB 3.0 hubs with 120µF output capacitance per port. IC Role / Device Role / Timing Role: High-side power switch providing current-limited, fault-protected 5V delivery with latch-off behavior during short circuits. Use Value: Prevents hub-wide shutdown due to single-port fault; FLG signal enables host microcontroller to isolate and reset affected port. | Use Scenario: Hot-swap power enable for HDMI/MHL + USB-C dual-function ports on laptop docking stations. IC Role / Device Role / Timing Role: Enables clean power sequencing to peripheral devices while blocking reverse current during disconnect events. Use Value: Eliminates battery drain from peripheral devices when dock is powered down; discharge function ensures safe VOUT decay before reconnection. |
| Set-Top Box USB Peripheral Interface | Industrial USB Host Controller Protection |
Use Scenario: Power switching for USB peripherals (e.g., Wi-Fi dongles, storage drives) in residential gateways with strict thermal constraints. IC Role / Device Role / Timing Role: Current-limited high-side switch with thermal shutdown (140°C) and UVLO (2.0V) for reliable operation across ambient temperatures (−40°C to +85°C). Use Value: Sustains operation under sustained 2A load without derating; thermal hysteresis prevents oscillation during intermittent overloads. | Use Scenario: Protecting industrial USB host controllers from field-induced short circuits in factory automation equipment. IC Role / Device Role / Timing Role: Fault-isolating power switch with 2µs short-circuit response and latch-off to prevent controller bus lockup. Use Value: Enables deterministic fault recovery via EN toggle-no software reset required; FLG signal feeds PLC I/O for real-time diagnostics. |
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 |
|---|---|---|---|
| AP2401ASN-7 | Active-low enable; identical RDS(ON), current limit, and protection features | Requires inverted logic drive; unsuitable where host MCU GPIO lacks pull-down or level-shifting capability | Select when system control logic is naturally active-low or shares enable signals with legacy components |
| TCK112G,315 (Nexperia) | 2.2A current limit; no integrated discharge; 10ms fault blanking; SO-8 only | Lacks output discharge and latch-off-requires external circuitry for VOUT decay and fault holdoff | Choose only if lower current rating suffices and board space allows SO-8; not drop-in for discharge-critical USB applications |
Compared with AP2401ASN-7, the AP2411ASN-7 simplifies control interface with active-high EN, while the TCK112G offers lower integration and no discharge-making AP2411ASN-7 preferable for compact, self-contained USB power management where latch-off and controlled discharge are mandatory.

FAQ
What happens after AP2411ASN-7 latches off due to overcurrent?
After latching off, the device remains disabled until the EN pin is toggled (high-to-low-to-high) or input power is cycled. The FLG pin stays low during latch-off, signaling persistent fault. No automatic recovery occurs-even if the short is removed-ensuring system-level fault containment and preventing uncontrolled re-enabling.
Does AP2411ASN-7 require external components for basic operation?
No external components are required for core functionality. A 0.1µF ceramic capacitor between IN and GND is mandatory for stability. Output discharge, UVLO, soft-start, and FLG deglitch are fully integrated. External resistors or capacitors are unnecessary unless specific timing adjustments or enhanced thermal management are needed.
How does the discharge function behave during normal operation?
The discharge function activates only when the device is disabled (EN = low). During normal enabled operation, the discharge path is inactive. When disabled, a 105Ω internal resistor discharges the output capacitor to <0.5V within 0.6ms-preventing residual voltage from interfering with subsequent hot-plug events or causing backfeed.
Can AP2411ASN-7 be used in automotive applications?
AP2411ASN-7 is specified for −40°C to +85°C ambient operation and qualified to IEC60950-1, but it is not AEC-Q200 qualified. It lacks automotive-specific reliability testing, extended temperature range (−40°C to +125°C), and PPAP documentation. Use in automotive infotainment or body electronics requires additional qualification and derating analysis.
