Product details
Overview
AP2311FGEG-7 from Diodes Incorporated is a single-channel, active-high enable, current-limited high-side power switch optimized for USB and hot-swap applications. It delivers 2.5A accurate current limiting, 70mΩ typical RDS(ON) at 5V, and fast 2µs short-circuit response time. The device integrates output discharge, reverse current blocking, UVLO (2.0V threshold), and fault reporting via open-drain FLG with 7ms deglitch - used in LCD TV power rails and USB hub load switching.
For engineers reviewing the AP2311FGEG-7 datasheet, AP2311FGEG-7 pinout, AP2311FGEG-7 application, or AP2311FGEG-7 equivalent, key selection considerations include active-high EN polarity, U-DFN3030-8 (Type E) package thermal performance (θJA = 84°C/W), integrated discharge path (RDIS = 100Ω), and compliance with USB power delivery robustness requirements.
Technical Context
The AP2311FGEG-7 implements a P-channel MOSFET high-side switch with embedded current-sense FET architecture, eliminating external sense resistors while maintaining precise 2.5A over-current trip (±10% tolerance). Its control logic includes built-in soft-start (0.6ms typical tR) and UVLO hysteresis (50mV) to prevent erratic turn-on during brown-out conditions.
Thermal protection uses die-temperature sensing with +140°C shutdown threshold and +20°C hysteresis, enabling automatic thermal cycling under sustained overload. The FLG output combines over-current and over-temperature detection with hardware deglitching - no external RC network required - and remains asserted until both faults clear.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typ., ±10% accuracy ensures consistent inrush and short-circuit current clamping without derating. |
| RDS(ON) | 70mΩ max @ 25°C, 5V IN - enables low power loss (≤350mW at 2A) in compact U-DFN3030-8 package. |
| Short-Circuit Response | 2µs - limits energy dissipation during fault events, reducing stress on downstream capacitors and PCB traces. |
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0/3.0 bus voltage range and 3.3V system rails. |
| Enable Polarity | Active-high - simplifies interface with microcontroller GPIOs without level-shifting or inverters. |
| FLG Blanking Time | 7ms typ. - suppresses false fault reporting during capacitive load turn-on transients. |
| Discharge Resistance | 100Ω - provides controlled VOUT discharge (<0.6ms to <0.5V) when disabled, preventing floating rail issues. |
Pinout & Package
AP2311FGEG-7 is housed in a 3.0mm × 3.0mm × 0.55mm U-DFN3030-8 (Type E) package with exposed thermal pad. This lead-free, halogen-free "Green" package achieves θJA = 84°C/W with recommended thermal vias to internal ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; must be connected to PCB ground plane with low-inductance routing. |
| IN | Power input | Accepts 2.7–5.5V supply; requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin. |
| EN | Enable control | Active-high digital input; 2V min VIH ensures compatibility with 3.3V logic without pull-up. |
| FLG | Fault indicator | Open-drain output pulled low during over-current or over-temperature; 7ms deglitch prevents false triggers. |
| OUT | Switched output | Delivers regulated current to load; all OUT pins internally paralleled for higher current capability. |
| NC | No connection | Internally unconnected; recommended to tie externally to OUT for mechanical stability and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 100Ω internal discharge path reduces VOUT to <0.5V in ≤0.6ms upon disable - eliminates need for external bleed resistor. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled (IREV ≤ 0.01µA @ VOUT = 5V), protecting upstream supplies. |
| Built-in Soft-Start | 0.6ms typical rise time (tR) limits inrush current into heavy capacitive loads (e.g., 120µF USB ports). |
| UVLO with Hysteresis | 2.0V turn-on / 1.95V turn-off threshold prevents oscillation during input ramp-up or brown-out. |
| ESD Robustness | 2kV HBM / 200V MM rating enables handling in standard assembly environments without special precautions. |
Applications
| USB 3.0 Hub Power Switching | LCD Monitor Backlight Rail Control |
|---|---|
|
Use Scenario: Power sequencing for multi-port USB 3.0 hubs with individual port current limiting and fault isolation. IC Role / Device Role / Timing Role: High-side power switch managing 5V VBUS distribution per port, with FLG reporting over-current to host controller. Use Value: Enables per-port hot-plug compliance and prevents bus-wide shutdown during single-port short circuits. |

| Set-Top Box USB Peripheral Port | Industrial Docking Station Power Management |
|
Use Scenario: Isolating USB peripheral ports (keyboard/mouse/storage) from main SoC power domain in residential gateways. IC Role / Device Role / Timing Role: Active-high enable switch with reverse current blocking, ensuring peripherals remain powered only when host is active. Use Value: Prevents battery drain in attached peripherals when STB enters deep sleep mode (EN = low disables OUT and discharge path). |
Use Scenario: Managing 5V auxiliary power to docking connectors in rugged industrial tablet docks. IC Role / Device Role / Timing Role: Hot-swap power switch with thermal cycling protection and FLG-driven system-level fault logging. Use Value: Sustains operation under continuous 2A load at +70°C ambient while reporting faults to BMC for predictive maintenance. |
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 |
|---|---|---|---|
| AP2301FGEG-7 | Same package and RDS(ON), but active-low EN and identical current limit (2.5A). | Requires inverted logic drive; unsuitable where MCU GPIOs lack open-drain or inversion capability. | Select when existing firmware uses active-low enable signaling and board layout cannot accommodate level shift. |
| TCK107AG,LF | 2.2A current limit, 85mΩ RDS(ON), 1.8–6.0V input range, no integrated discharge function. | Lacks output discharge - requires external 10kΩ resistor to GND for safe VOUT decay. | Choose for wider VIN range and lower quiescent current (30µA vs. 60µA), accepting added BOM cost and layout area. |
Compared with AP2301FGEG-7, AP2311FGEG-7 offers direct GPIO compatibility without logic inversion; versus TCK107AG, it delivers tighter current accuracy, faster fault response, and eliminates external discharge components - critical for space-constrained USB and display applications.

FAQ
What is the maximum continuous load current supported by AP2311FGEG-7?
The AP2311FGEG-7 supports up to 2.0A continuous load current per its Recommended Operating Conditions, with a guaranteed 2.5A current-limit threshold across -40°C to +85°C ambient. Derating is required above +70°C ambient due to thermal resistance (84°C/W) and junction temperature limit (+150°C); at +85°C, max continuous current drops to ~1.5A with proper PCB copper area.
Does AP2311FGEG-7 require external components for basic operation?
No external components are required for core functionality: a 0.1µF ceramic capacitor from IN to GND is mandatory for stability, but the FLG deglitch, output discharge, soft-start, and UVLO are fully integrated. External components become necessary only for specific use cases - e.g., a pull-up resistor on FLG for microcontroller interrupt detection, or larger bulk capacitance (>120µF) on OUT for high-inrush loads.
How does the FLG pin behave during thermal shutdown?
During thermal shutdown, the FLG pin asserts low after the 7ms deglitch timeout and remains low until both the over-temperature condition clears (die cools below +120°C) and any concurrent over-current fault is resolved. FLG deasserts only when the device resumes normal conduction - it does not pulse during thermal cycling, providing unambiguous fault status to the host system.
Can AP2311FGEG-7 be used in automotive infotainment USB ports?
AP2311FGEG-7 is qualified for industrial temperature range (-40°C to +85°C) and meets USB electrical compliance, but it is not AEC-Q100 qualified. For automotive infotainment, it may be used in non-safety-critical accessory ports if customer qualification (including extended temperature testing and EMC validation) is performed - however, Diodes' automotive-grade alternatives like AP22651Q are recommended for production automotive designs.
