Product details
Overview
AP22615BWU-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 capability. It operates from 3.0V to 5.5V input, features 40mΩ RDS(ON), 110µs OVP recovery during FRS, and integrated discharge on OUT - optimized for USB hot-swap, SSD power sequencing, and ultrabook load switching.
For engineers reviewing the AP22615BWU-7 datasheet, AP22615BWU-7 pinout, AP22615BWU-7 application, or AP22615BWU-7 equivalent, key selection criteria include adjustable OCP via ISET resistor, 7ms FLG deglitching, reverse-current blocking at 65mV, thermal shutdown at +140°C with +35°C hysteresis, and TSOT26 package compatibility with high-density PCB layouts.
Technical Context
The AP22615 implements a thermally robust N-channel MOSFET high-side switch with integrated current-sense FET (no external shunt), UVLO (2.5V turn-on, 2.3V turn-off), and dual-stage protection: fast-response OVP (1µs trip) with auto-recovery and short-circuit response in 5µs. Its ISET pin enables precise current-limit tuning via external resistor (ILIM = 6800/RLIM Ω).
It supports both active-high and active-low EN logic, includes internal discharge path on OUT (RDIS = 100Ω), and delivers USB-compliant voltage recovery (<150µs) during fast role-swap events - critical for bidirectional USB-C power delivery systems requiring seamless VBUS polarity reversal without latch-up or bus collapse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.0V to 5.5V - supports full USB 2.0/3.x and USB PD 3.0 VBUS range without external regulation. |
| RDS(ON) | 40mΩ typical - enables 3A continuous load with <500mW conduction loss at 5V input. |
| Adjustable Current Limit | 0.4A to 4.0A via ISET resistor - allows precise OCP tailoring for SSDs, USB ports, or low-power peripherals. |
| OVP Trip Threshold | 5.7V ±0.2V - clamps output above safe USB voltage, with 100mV hysteresis to prevent oscillation. |
| Fast Role-Swap Recovery | <110µs to 4.75V - ensures uninterrupted power negotiation during USB-C DRP transitions. |
| Thermal Shutdown | +140°C with +35°C hysteresis - enables self-resetting fault handling under sustained overload. |
| FLG Blanking Time | 7ms typical - suppresses false fault reporting during inrush or capacitive-load transients. |
Pinout & Package
AP22615BWU-7 is housed in a RoHS-compliant, green TSOT26 package (2.9mm × 1.6mm × 0.6mm), thermally optimized with 80°C/W junction-to-ambient resistance and integrated discharge circuitry on the OUT pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Power Input | Accepts 3.0–5.5V supply; connects to upstream VBUS or regulated rail. |
| 2: GND | Ground Reference | Common return for internal control circuitry and power path; requires low-impedance PCB plane. |
| 3: FLG | Open-Drain Fault Flag | Active-low signal indicating OVP, OCP, or overtemperature; 7ms deglitch prevents false triggers. |
| 4: EN | Enable Control | Logic-compatible input supporting active-high or active-low configuration; must not float. |
| 5: ISET | Current-Limit Programming | Connects external resistor to set ILIM = 6800/RLIM Ω; unused on AP22815. |
| 6: OUT | Switched Output | Delivers controlled power to load; integrates 100Ω discharge path when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Output Overvoltage Protection | Auto-recovering clamp at 5.7V with 1µs response - eliminates need for external TVS in USB applications. |
| Adjustable Overcurrent Limit | 0.4–4.0A via single resistor - replaces fixed-limit switches and avoids overdesign in mixed-load systems. |
| Integrated Discharge Path | 100Ω internal resistor on OUT - safely bleeds residual charge from 100µF+ output caps without external components. |
| USB PD3.0 Fast Role-Swap | <110µs VOUT recovery - maintains power integrity during USB-C DRP transitions without host intervention. |
| Reverse-Voltage Blocking | 65mV threshold - prevents backfeed from downstream loads into upstream rails, protecting source converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22815WU-7 | Fixed 3.6A current limit; no ISET pin; TSOT25 package (85°C/W RθJA). | Lacks adjustable OCP; suited for cost-sensitive, single-OCP designs where precision tuning is unnecessary. | Select when design uses only one current threshold and board space allows larger thermal footprint. |
| TCK127AG,TL | 2.5A max, 55mΩ RDS(ON), no OVP, no FRS, SOT-23-6 package. | No output overvoltage protection or USB PD role-swap support; limited to basic hot-swap. | Choose only if OVP, FRS, and >3A capability are non-critical and lower BOM count outweighs protection gaps. |
Compared with AP22815WU-7 and TCK127AG, the AP22615BWU-7 uniquely combines adjustable current limiting, USB PD3.0 fast role-swap, and integrated OVP - making it the only option among the three qualified for next-generation USB-C DRP endpoints requiring robust, standards-compliant power switching.

FAQ
What is the function of the ISET pin on AP22615BWU-7?
The ISET pin sets the adjustable overcurrent limit using an external resistor: ILIM (A) = 6800 / RLIM (Ω). With RLIM between 1.94kΩ and 6.8kΩ, current limit ranges from 0.4A to 4.0A. This pin is NC on AP22815 and absent in fixed-limit variants. No pull-up/down is required; direct resistor connection to GND suffices.
Does AP22615BWU-7 support both active-high and active-low enable configurations?
Yes - the EN pin accepts either logic polarity. Active-high mode requires VIH ≥ 1.2V (at VIN = 5V); active-low mode triggers at VIL ≤ 0.4V. The device does not auto-detect polarity; configuration is determined by system-level GPIO drive. Floating EN is prohibited and may cause undefined behavior.
How does the FLG pin behave during overvoltage, overcurrent, or overtemperature events?
FLG asserts low after a nominal 7ms deglitch timeout upon detection of any fault condition. It remains low until the fault clears and the device recovers autonomously. During recovery, FLG returns high only after VOUT stabilizes within spec and temperature drops below the hysteresis threshold (+105°C). No external pull-up is mandatory but recommended for noise immunity.
Can AP22615BWU-7 be used in automotive applications?
No - AP22615BWU-7 is not AEC-Q100 qualified and lacks automotive-grade qualification, PPAP documentation, or IATF 16949 manufacturing certification. Diodes explicitly states that automotive use requires contacting their sales team for alternate parts. This device is rated for -40°C to +85°C ambient operation and intended for commercial/industrial computing and consumer electronics.
