Product details
Overview
AP22814ASN-7 from Diodes Incorporated is a single-channel, current-limited, high-side load switch optimized for USB and hot-swap applications. It features 50 mΩ RDS(ON), 3.0 A over-current limit, 6 ms FLG deglitch timeout, integrated output discharge, and reverse-voltage protection with 50 mV trip threshold - enabling robust power sequencing in ultrabooks and SSDs.
For engineers reviewing the AP22814ASN-7 datasheet, AP22814ASN-7 pinout, AP22814ASN-7 application, or AP22814ASN-7 equivalent, key selection criteria include its U-DFN2020-6 thermal performance (RθJA = 100 °C/W), active-high enable variant, controlled 2.1 ms typical rise time, and auto-recovery protection architecture for capacitive-load environments.
Technical Context
The AP22814ASN-7 integrates an N-channel MOSFET power switch with precision current-sense FET-based overload detection, eliminating external sense resistors. Its UVLO triggers at 2.0 V (with 180 mV hysteresis) and disables the switch until input stabilizes - critical for hot-plug reliability.
Thermal shutdown activates at +140 °C with +35 °C hysteresis, enabling safe cycling under sustained short-circuit conditions. The open-drain FLG output asserts low after 6 ms blanking to suppress false fault reporting during inrush or transient overloads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports full USB 2.0/3.0 bus voltage range with margin. |
| RDS(ON) | 50 mΩ typ - minimizes conduction loss and self-heating at 3 A continuous load. |
| Over-Current Limit | 3.45 A typ - sustains 3.0 A nominal load while tolerating brief surges without shutdown. |
| FLG Blanking Time | 6 ms typ - prevents false fault latching during capacitor charging transients. |
| Output Discharge Resistance | 90 Ω typ - discharges 1 µF output cap to <0.5 V in ≤0.4 ms for safe hot-removal. |
| Reverse-Voltage Trip | 50 mV - blocks reverse current when VOUT exceeds VIN by ≥50 mV, protecting upstream sources. |
| Thermal Shutdown Threshold | +140 °C - initiates automatic power cycling before junction damage occurs. |
Pinout & Package
AP22814ASN-7 is housed in a thermally enhanced U-DFN2020-6 package with exposed thermal pad (recommended to be connected to PCB ground plane). Pin assignments are validated per Diodes DS39137 Rev. 1–2, Figure 1 (Top View).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Power Input | Connects to 2.7–5.5 V supply; requires 1 µF ceramic bypass close to pin. |
| 2 (GND) | Ground Reference | Common return path for control logic and power switch; ties to thermal pad. |
| 3 (FLG) | Fault Reporting Output | Open-drain active-low flag; asserts after 6 ms deglitch on over-current or over-temperature. |
| 4 (EN) | Enable Control | Active-high logic input (VIH ≥ 1.5 V); must not float - tie low during power transitions. |
| 5 (OUT) | Switched Power Output | Delivers regulated load current; requires 0.1 µF + ≥10 µF bulk capacitance to GND. |
| 6 (NC) | No Internal Connection | Unbonded pad; electrically isolated - no routing or connection required. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in Soft-start | 0.6 ms typical rise time - limits inrush current into heavy capacitive loads (e.g., USB ports, SSDs). |
| Integrated Output Discharge | 90 Ω internal discharge path - eliminates need for external bleed resistor in hot-swap systems. |
| Reverse Current Blocking | 50 mV comparator threshold - prevents backfeed from downstream circuits during power-off or fault. |
| Auto-Recovery Protection | Over-current, short-circuit, and over-temperature faults recover automatically once condition clears - no reset required. |
| UVLO with Hysteresis | 2.0 V turn-on / 1.82 V turn-off - ensures clean power-up sequencing and avoids brown-out oscillation. |
Applications
| USB 3.0 Port Power Switching | SSD Power Sequencing |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TCK107AG,3 | Lower 2.5 A current limit; 70 mΩ RDS(ON); no integrated discharge; SOT-23-5 package. | Lacks output discharge and reverse-voltage protection - requires external components for hot-swap safety. | Choose only if board space is constrained and discharge/reverse-blocking are handled externally. |
| TPS22915BYFPR | 3.5 A limit; 42 mΩ RDS(ON); 1.8–5.5 V input; no UVLO hysteresis; WSON-6 package. | Higher max current but lacks 6 ms FLG deglitch - more prone to false fault reporting with large CL. | Select when higher current headroom is needed and system-level filtering can compensate for missing deglitch. |
Compared with TCK107AG,3 and TPS22915BYFPR, AP22814ASN-7 uniquely combines 3.0 A capability, integrated discharge, 50 mV reverse-voltage trip, and factory-trimmed 6 ms FLG blanking - delivering out-of-box USB-compliant robustness without design compromises.

FAQ
What is the function of the NC pin on AP22814ASN-7?
Pin 6 is a no-connect terminal with no internal bond wire or circuit connection. It is an unpopulated pad used for mechanical symmetry and thermal relief in the U-DFN2020-6 package. Do not route signals or connect it to any net - leaving it floating or grounded has no electrical effect.
Does AP22814ASN-7 support active-low enable?
No - AP22814ASN-7 is the 'A' suffix variant, meaning active-high enable (EN high = switch on). The 'B' variant (e.g., AP22814BSN-7) provides active-low logic. This distinction is fixed per part number and cannot be configured via external circuitry.
How does the output discharge function operate during disable?
When EN is driven low, the internal discharge FET activates, connecting OUT to GND through a ~90 Ω path. This safely bleeds stored charge from output capacitors (e.g., 100 µF) to <0.5 V within 0.4 ms - preventing residual voltage that could cause latch-up or ESD damage during connector removal.
Can AP22814ASN-7 be used outside USB applications?
Yes - its 2.7–5.5 V input range, 3.0 A current capability, and comprehensive protection suite make it suitable for any 5 V or 3.3 V hot-swap or power-gating application, including industrial I/O modules, telecom line cards, and medical device sub-systems where controlled power delivery and fault resilience are required.
