Product details
Overview
AP2301AFGE-7 from Diodes Incorporated is a single-channel, current-limited high-side power switch optimized for USB and hot-swap applications. It features 2.5A accurate current limiting, 70mΩ on-resistance at 5V, 2µs short-circuit response time, integrated output discharge, and reverse current blocking. It operates across 2.7V–5.5V input voltage and delivers controlled power switching in LCD TVs, docking stations, and USB HUBs.
For engineers reviewing the AP2301AFGE-7 datasheet, AP2301AFGE-7 pinout, AP2301AFGE-7 application, or AP2301AFGE-7 equivalent, key selection criteria include enable polarity (active-low), thermal shutdown threshold (+140°C), UVLO (2.0V typ), FLG deglitch timing (7ms), and U-DFN3030-8 (Type E) package compatibility with high-density PCB layouts.
Technical Context
The AP2301AFGE-7 integrates a P-channel MOSFET high-side switch with real-time current sensing via a dedicated sense FET-eliminating external shunt resistors while maintaining low RDS(ON). Its protection architecture combines fast over-current detection (2µs), thermal shutdown with +20°C hysteresis, and undervoltage lockout (2.0V rising threshold) to ensure robust operation during hot-plug events.
It implements an active N-MOS discharge path activated upon disable, delivering 105Ω typical discharge resistance for controlled VOUT decay. The open-drain FLG output reports combined over-current/over-temperature faults with built-in 7ms blanking to suppress false triggers from capacitive load inrush.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical; clamps output current precisely during overload without latch-off, enabling safe recovery. |
| RDS(ON) | 70mΩ max at 25°C, 5V IN; minimizes conduction loss and self-heating under 2A continuous load. |
| Short-Circuit Response | 2µs; enables rapid current limiting before fault energy damages downstream components. |
| UVLO Threshold | 2.0V (rising); prevents erratic turn-on during brown-out or slow power ramp-up in USB host systems. |
| FLG Blanking Time | 7ms typical; filters transient inrush spikes from heavy capacitive loads without external RC networks. |
| Discharge Resistance | 105Ω typical; ensures controlled VOUT decay <0.6ms to <0.5V, preventing backfeed into disabled rails. |
| Thermal Shutdown | +140°C junction; cycles switch off/on until fault clears, protecting die integrity during sustained shorts. |
Pinout & Package
AP2301AFGE-7 uses the U-DFN3030-8 (Type E) 3.0mm × 3.0mm, 0.5mm pitch, 8-pin package with exposed thermal pad. Pin 1 is OUT, Pin 2 is FLG, Pin 3 is EN, Pin 4 is GND, Pin 5 is IN, Pin 6 is NC, and Pins 7–8 are tied internally to OUT and GND respectively per datasheet top-view layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pins 1, 7) | Power Output Terminal | High-side switched output; pins 1 and 7 must be externally shorted to share current and reduce impedance. |
| FLG (Pin 2) | Fault Reporting Output | Open-drain, active-low signal asserting after 7ms deglitch when over-current or over-temperature occurs. |
| EN (Pin 3) | Enable Control Input | Active-low logic interface; pulls low to enable switch, high or floating to disable with automatic discharge activation. |
| GND (Pin 4, 8) | Ground Reference | Primary ground return; Pin 8 connects to exposed thermal pad, which must be soldered to PCB ground plane for thermal performance. |
| IN (Pin 5) | Input Power Supply | 2.7–5.5V supply input; requires ≥0.1µF ceramic capacitor placed adjacent to minimize noise and support inrush current. |
| NC (Pin 6) | No Internal Connection | Not bonded; recommended to tie externally to OUT for mechanical stability and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 105Ω internal discharge path activates automatically on disable, eliminating need for external bleed resistor. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled, critical for shared-bus USB and dual-port applications. |
| Built-in Soft-Start | 0.6ms typical rise time limits inrush current into large capacitive loads, reducing stress on upstream regulators. |
| 7ms FLG Deglitch | Hardware-blanked fault reporting eliminates false flags from transient load surges-no external filtering required. |
| Thermal Cycling Protection | +140°C shutdown with +20°C hysteresis enables safe auto-recovery during intermittent shorts without system reset. |
Applications
| USB 2.0/3.0 Hub Power Switching | LCD Monitor Port Management |
|---|---|

IC Role / Device Role / Timing Role: High-side switch managing VBUS delivery to charge circuitry while isolating data lines. Use Value: Active-low EN allows direct connection to host GPIO; discharge function prevents parasitic drain when port is idle. |
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 |
|---|---|---|---|
| AP2311AFGE-7 | Same silicon, active-high EN instead of active-low; identical RDS(ON), current limit, and protection features. | Requires inverted enable logic; suitable where host MCU GPIO defaults high or lacks pull-down capability. | Select when system-level enable signaling is active-high; no change to thermal, timing, or protection behavior. |
| TCK112G,LF | 2.2A current limit, 90mΩ RDS(ON), 10µs fault response, no integrated discharge; requires external discharge resistor. | Lacks output discharge and has slower fault response; used in cost-sensitive industrial controls with lower current demands. | Choose only if 2.2A limit suffices and board space allows external 10kΩ discharge resistor; not drop-in compatible. |
Compared with AP2311AFGE-7, the AP2301AFGE-7 offers identical protection and performance but simplifies interface design in active-low control systems; versus TCK112G, it provides faster fault response, lower conduction loss, and eliminates BOM components via integrated discharge.

FAQ
What is the maximum continuous load current supported by AP2301AFGE-7?
The AP2301AFGE-7 supports up to 2.0A continuous load current per its datasheet specifications. Its 2.5A current limit is designed for short-duration overload conditions-not steady-state operation. Sustained current must remain ≤2.0A to maintain junction temperature within safe limits, especially in the U-DFN3030-8 package with θJA = 84°C/W.
Does AP2301AFGE-7 require external components for fault reporting or discharge?
No. The AP2301AFGE-7 integrates all essential functions: the FLG output includes 7ms hardware deglitching to prevent false over-current reporting, and the output discharge path is fully internal (105Ω typical). No external resistors, capacitors, or diodes are needed for basic operation, simplifying layout and reducing BOM count.
How does the thermal shutdown and recovery behavior work in AP2301AFGE-7?
The device shuts down when junction temperature reaches +140°C and remains off until temperature drops by ~20°C due to built-in hysteresis. During sustained short-circuit conditions, it cycles on/off autonomously-enabling safe fault containment without external intervention. This behavior is confirmed in the datasheet's thermal protection section and validated in Figure 6's short-circuit recovery waveforms.
Can AP2301AFGE-7 be used in dual-role USB-C or MHL applications?
Yes. Its reverse current blocking, fast 2µs fault response, and integrated discharge make it suitable for dual-purpose ports like HDMI/MHL where data and power share one connector. However, VIN must reach full operating voltage before EN is asserted to avoid overstress on the discharge transistor-per Application Information Section 4.6 in DS37743 Rev. 2-2.
