Product details
Overview
AP22615AWU-7 from Diodes Incorporated is a 3A single-channel high-side power distribution switch with output overvoltage protection (OVP), adjustable current limiting (0.4–4.0A), and USB PD3.0 fast role-swap support. It operates from 3.0V to 5.5V input, features 40mΩ RDS(ON), 110µs OVP recovery during FRS events, and integrated discharge circuitry on the OUT pin. It is designed for hot-swap USB power delivery in ultrabooks and SSDs.
For engineers reviewing the AP22615AWU-7 datasheet, AP22615AWU-7 pinout, AP22615AWU-7 application, or AP22615AWU-7 equivalent, this device delivers precise current-limit configuration via external ISET resistor, auto-recovering OVP/overcurrent/short-circuit/overtemperature protection, and 7ms deglitch on FLG-enabling robust load switching without external components in space-constrained USB-C and embedded power rail designs.
Technical Context
The AP22615 implements a thermally protected N-channel MOSFET high-side switch with integrated voltage sense, current sense, and discharge control logic. Its dual-mode EN input supports both active-high and active-low control, while the ISET pin enables programmable current limit via RLIM resistor (ILIM = 6800/RLIM Ω).
OVP detection triggers at 5.7V (±0.2V) with 100mV hysteresis and responds within 1µs; short-circuit response occurs in ≤5µs. The device integrates UVLO (2.5V trip, 180mV hysteresis), reverse-voltage blocking (>65mV VOUT–VIN), and thermal shutdown at +140°C with +35°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - Ensures compatibility with USB 3.3V/5V rails and avoids UVLO activation during brown-out. |
| RDS(ON) | 40mΩ typical - Enables 3A continuous operation with <120mW conduction loss at full load (TA = 25°C). |
| Adjustable Current Limit | 0.4A to 4.0A via ISET resistor - Supports fine-grained load protection tuning for diverse capacitive and resistive loads. |
| OVP Response Time | 1µs - Limits transient overvoltage exposure to downstream USB PHY or PMIC before clamping activates. |
| Fast Role-Swap Recovery | <110µs to 4.75V - Meets USB PD3.0 specification for seamless source/sink transition without bus reset. |
| FLG Blanking Time | 7ms typical - Suppresses false fault reporting during inrush or heavy capacitive load turn-on without external RC. |
| Thermal Shutdown Threshold | +140°C with +35°C hysteresis - Enables self-resetting fault recovery after short-circuit removal without manual intervention. |
Pinout & Package
AP22615AWU-7 is housed in a RoHS-compliant, green TSOT26 package (2.9mm × 1.6mm × 0.6mm), optimized for thermal dissipation (RΘJA = 80°C/W) and PCB area efficiency in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Power Input | Accepts 3.0–5.5V supply; connects directly to upstream DC source or USB VBUS. |
| 2: GND | Ground Reference | Common return path for internal circuitry, current sense, and thermal sensing; must be low-impedance. |
| 3: FLG | Open-Drain Fault Flag | Active-low signal indicating OVP, overcurrent, or overtemperature; 7ms deglitch prevents false triggers. |
| 4: EN | Enable Control | Configurable active-high or active-low logic input; requires ≥1.2V high or ≤0.4V low for reliable switching. |
| 5: ISET | Current-Limit Programming | Connects external resistor (1.94kΩ–6.8kΩ) to set ILIM = 6800/RLIM; only functional on AP22615 variant. |
| 6: OUT | Switched Output | Delivers controlled power to load; integrates internal discharge path to safely bleed residual VOUT when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Discharge Circuitry on OUT | Eliminates need for external bleeder resistor; discharges output capacitance rapidly upon disable to prevent backfeed. |
| USB PD3.0 Fast Role-Swap Support | VOUT recovers to valid USB range (4.75–5.25V) within 110µs after polarity reversal-critical for dual-role USB-C ports. |
| Auto-Recovering Protection Suite | OVP, overcurrent, short-circuit, overtemperature, and reverse-current faults all recover automatically once condition clears. |
| Programmable Current Limit via ISET | Enables one-part-number flexibility across multiple load profiles (e.g., 0.75A SSD vs. 3.6A USB hub) using only resistor change. |
| Reverse-Voltage Blocking Threshold | 65mV VOUT–VIN trip point prevents backflow from powered peripherals into host supply during hot-plug events. |
Applications
| Ultrabook Power Sequencing | USB-C Dual-Role Port |

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 |
|---|---|---|---|
| AP22815AWN-7 | Fixed 3.6A current limit; no ISET pin; TSOT25 package (RΘJA = 85°C/W); same OVP/FRS specs. | Lacks adjustable current limit; suited for fixed-load applications where design margin is known and stable. | Select when board layout prioritizes smaller footprint (TSOT25) and current requirement is consistently near 3.6A. |
| TCK107AG,TL | Toshiba part; 2.5A max; 30mΩ RDS(ON); no OVP or FRS; only basic overcurrent/thermal protection. | No output overvoltage protection or USB PD fast role-swap; limited to non-USB hot-swap use cases. | Choose only if OVP and FRS are unnecessary and lower RDS(ON) is critical for ultra-low-loss 2.5A rails. |
Compared with AP22815AWN-7, AP22615AWU-7 offers programmable current limiting and superior thermal performance (TSOT26), while TCK107AG lacks OVP and FRS-making AP22615AWU-7 the sole option meeting full USB PD3.0 hot-swap requirements with adjustable protection.

FAQ
What is the function of the ISET pin on AP22615AWU-7?
The ISET pin sets the adjustable overcurrent limit by connecting an external resistor (RLIM) between ISET and GND. The current limit follows ILIM (A) = 6800 / RLIM (Ω), supporting 0.4A to 4.0A range with 1% tolerance resistors. This pin is unused (NC) on AP22815 and is exclusive to AP22615 for design flexibility across varying load profiles.
Does AP22615AWU-7 support both active-high and active-low enable configurations?
Yes-EN pin behavior is configurable via internal strap options at manufacture. The AP22615AWU-7 variant supports active-high enable (EN ≥1.2V turns ON), while other variants like AP22615BWU-7 support active-low. Logic thresholds are guaranteed: VIL ≤0.4V and VIH ≥1.2V at VIN = 5V, ensuring GPIO compatibility without level-shifting.
How does the discharge function operate on the OUT pin?
When EN is de-asserted, an internal NMOS transistor activates between OUT and GND, providing a ~100Ω discharge path. This safely bleeds residual voltage from output capacitors (e.g., 100µF SSD bulk caps) within milliseconds, preventing backfeed into upstream supplies and enabling safe hot-plug removal without external components.
What protection features activate during a short-circuit event?
During output short-to-GND, AP22615AWU-7 immediately limits current to ISHORT ≈1A (typical), responds within ≤5µs, and asserts FLG after 7ms deglitch. If sustained, thermal shutdown triggers at +140°C, cycling until fault clears. All protections-OVP, overcurrent, short-circuit, overtemperature, and reverse-current-recover automatically once conditions normalize.
