Product details
Overview
AP22814AW5-7 from Diodes Incorporated is a single-channel, active-high enable, 3.0A current-limited high-side load switch optimized for USB and hot-swap applications. It features 50mΩ RDS(ON), 2.7–5.5V input range, integrated output discharge, reverse-current blocking, and 6ms deglitch on the open-drain FLG pin-enabling robust power sequencing in ultrabooks and SSDs.
For engineers reviewing the AP22814AW5-7 datasheet, AP22814AW5-7 pinout, AP22814AW5-7 application, or AP22814AW5-7 equivalent, key selection criteria include its 3.0A overcurrent limit (vs. 2.5A in AP22804), SOT25 package thermal resistance (175°C/W), controlled 2.1ms typical rise time, and active-high EN logic compatibility with standard GPIO interfaces.
Technical Context
The AP22814AW5-7 integrates an N-channel MOSFET with precision current-sense FET architecture to deliver accurate 3.45A typical overcurrent limiting without external resistors. Its UVLO threshold is fixed at 2.0V with 180mV hysteresis, ensuring clean turn-on during hot-plug events.
Thermal shutdown activates at +140°C with +35°C hysteresis, enabling auto-recovery cycling under sustained overload. The FLG pin asserts low after 6ms deglitch upon overcurrent or overtemperature fault, eliminating false triggers from capacitive inrush transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0/3.0 bus voltage compliance and wide-system rail compatibility. |
| RDS(ON) | 50mΩ typ - minimizes conduction loss and self-heating at 3A load (150mW dissipation). |
| Current Limit | 3.45A typ - precisely clamps output current during short-circuit, preventing upstream supply collapse. |
| Rise Time (tR) | 2.1ms typ - ensures controlled inrush into 100μF+ loads, avoiding input rail droop or reset glitches. |
| FLG Blanking Time | 6ms typ - suppresses false fault reporting during capacitor charging transients without external RC networks. |
| Discharge Resistance | 115Ω typ - actively discharges output capacitance to <0.5V within 0.4ms when disabled, preventing backfeed. |
| Reverse-Voltage Trip | 50mV - blocks reverse current flow when VOUT exceeds VIN by ≥50mV, protecting upstream sources. |
Pinout & Package
AP22814AW5-7 is housed in a RoHS-compliant, lead-free SOT25 (SOT-23-5) package with exposed pad for enhanced thermal performance. Pin 1 is OUT, Pin 2 is GND, Pin 3 is FLG, Pin 4 is EN, and Pin 5 is IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Switched Output Node | Drives downstream load; requires 0.1μF ceramic + ≥10μF bulk capacitor to GND for stability and short-circuit immunity. |
| 2 (GND) | Power Ground Reference | Primary return path for load current and internal bias; must connect directly to low-impedance ground plane. |
| 3 (FLG) | Open-Drain Fault Indicator | Active-low signal asserted after 6ms deglitch on overcurrent/overtemperature; pulls low via internal ~40Ω FET. |
| 4 (EN) | Enable Control Input | Active-high logic interface (VIH ≥1.5V); must not float-tie to GND or host GPIO for sequencing control. |
| 5 (IN) | Input Power Supply | Accepts 2.7–5.5V source; requires 1μF X7R/X5R ceramic bypass capacitor placed adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Soft-Start | 0.6ms typical rise time control prevents inrush current spikes into heavy capacitive loads. |
| Auto-Recovery Protection | Overcurrent, short-circuit, and overtemperature faults trigger automatic recovery cycling without latch-off. |
| Output Discharge Path | Internal 115Ω discharge FET eliminates need for external bleed resistor, reducing BOM count and board space. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when input is off or absent, critical for multi-rail systems. |
| No External Components Required | 6ms FLG deglitch, UVLO, thermal shutdown, and discharge are fully internal-no RC timing networks needed. |
Applications
| USB Power Delivery Switching | SSD Power Sequencing |
|---|---|
|
Use Scenario: Hot-plug insertion of USB peripherals into ultrabook ports with 100μF+ output capacitance. IC Role / Device Role / Timing Role: High-side power switch controlling VBUS delivery; enables/disables per-port power with GPIO-driven EN. Use Value: Prevents input rail droop and system resets during plug-in by limiting inrush to 3.45A and discharging residual VBUS on disconnect. |
Use Scenario: Controlled power-up of NAND flash and controller in M.2 SATA SSD modules. IC Role / Device Role / Timing Role: Load switch managing 3.3V or 5V rail sequencing; coordinates with host BIOS via EN assertion timing. Use Value: Ensures clean power ramp with 2.1ms rise time and eliminates backfeed from SSD capacitors during sleep/wake transitions. |
| Notebook System Rail Isolation | Set-Top Box USB Hub Management |
|
Use Scenario: Isolating auxiliary rails (e.g., camera, audio codec) from main 5V system bus in thin-and-light notebooks. IC Role / Device Role / Timing Role: Independent high-side switch providing per-subsystem power control and fault reporting via FLG. Use Value: Enables selective subsystem shutdown without affecting core logic; FLG alerts host of overcurrent before thermal shutdown occurs. |
Use Scenario: Managing power to front-panel USB ports in cable/satellite STBs with shared 5V supply. IC Role / Device Role / Timing Role: Per-port load switch with reverse-voltage protection to prevent backfeed from powered peripherals into STB USB hub. Use Value: Blocks >50mV reverse voltage automatically, protecting hub ICs from damage when external devices remain powered. |
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 |
|---|---|---|---|
| AP22814BW5-7 | Active-low EN instead of active-high; identical RDS(ON), current limit, and protection features. | Requires inverted GPIO control signal; no change in thermal or sequencing behavior. | Select when host MCU uses active-low enable outputs or legacy control logic. |
| TCK112G,LF(TP) | Lower 2.5A current limit, 30mΩ RDS(ON), and 1.8–5.5V input range; lacks integrated discharge FET. | Needs external 10kΩ pull-down on DIS pin to enable discharge; less suitable for USB hot-swap with large caps. | Choose for cost-sensitive, lower-current designs where external discharge is acceptable and tighter RDS(ON) is prioritized. |
Compared with AP22814BW5-7, the AP22814AW5-7 simplifies GPIO interface design with active-high logic; versus TCK112G, it delivers higher current capability and eliminates external discharge components-reducing layout complexity and improving reliability in USB/SSD use cases.

FAQ
What is the maximum continuous output current rating for AP22814AW5-7?
The AP22814AW5-7 is rated for 3.0A maximum continuous output current, with a typical overcurrent limit of 3.45A at 5V input and 4.5V output. This value is validated across −40°C to +85°C ambient and accounts for thermal derating in the SOT25 package's 175°C/W junction-to-ambient resistance.
Does AP22814AW5-7 require external components for basic operation?
No external components are required for core functionality: the 6ms FLG deglitch, UVLO, thermal shutdown, and output discharge are fully internal. However, mandatory external capacitors include a 1μF ceramic on IN–GND and a 0.1μF ceramic plus ≥10μF bulk capacitor on OUT–GND to ensure stability and fault immunity.
How does the reverse-voltage protection function in AP22814AW5-7?
The device monitors the differential voltage (VOUT − VIN). If this exceeds +50mV for 6ms, the internal MOSFET turns off to block reverse current. Recovery occurs automatically when the differential falls below +25mV, enabling safe reconnection without manual reset.
Can AP22814AW5-7 be used in place of AP22804AW5-7?
Yes, but only if the higher 3.0A current limit is acceptable and beneficial. The AP22814AW5-7 shares identical pinout, package, EN polarity, and protection features with AP22804AW5-7, differing solely in overcurrent threshold (3.45A vs. 3.0A typ) and short-circuit limit (0.65A vs. 0.45A). No layout or firmware changes are needed.
