Product details
Overview
AP22652FDZ-7 from Diodes Incorporated is a single-channel, precision-adjustable, current-limited high-side power switch in W-DFN2020-6 (Type A1) package, delivering up to 2.1A continuous load current with ±7% current-limit accuracy at 1.735A (RLIM = 15kΩ), fast 5µs short-circuit response, and active-low enable logic - designed for USB-compliant hot-swap protection in set-top boxes and LCD monitors.
For engineers reviewing the AP22652FDZ-7 datasheet, AP22652FDZ-7 pinout, AP22652FDZ-7 application, or AP22652FDZ-7 equivalent, this device supports precision programmable current limiting (125–2665mA), reverse-current blocking during shutdown, integrated UVLO (2.65V), thermal shutdown at +145°C, and fault reporting via open-drain FAULT with 6ms deglitch - critical for robust USB power delivery and capacitive-load management.
Technical Context
The AP22652FDZ-7 implements a high-side N-channel MOSFET driver with slew-rate-controlled turn-on (0.5ms typical rise time) and built-in current-sense FET architecture - eliminating external sense resistors while maintaining <135mΩ RDS(ON) over -40°C to +85°C ambient. Its constant-current limiting mode activates within 5µs of overcurrent detection, clamping output current without latch-off.
It integrates undervoltage lockout (2.65V trip, 65mV hysteresis), reverse-voltage comparator (65mV threshold), and thermal shutdown with +40°C hysteresis. The ILIM pin accepts 10kΩ–210kΩ resistor to program current limit per validated polynomial equations, and FAULT provides open-drain fault signaling with blanking to suppress false triggers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Load Current | 2.1A continuous - supports USB PD-compliant downstream ports and high-capacitance loads (≥10µF). |
| Current-Limit Range | 125mA to 2665mA (typ) - set externally via RLIM; ±7% accuracy at 1.735A enables precise upstream supply coordination. |
| RDS(ON) | 65–135mΩ - low conduction loss across temperature ensures minimal voltage drop and thermal rise under full load. |
| Short-Circuit Response | 5µs (typ) - enables rapid current clamping before system-level damage occurs in hot-plug scenarios. |
| Enable Logic | Active-low EN - simplifies direct interface with microcontroller GPIOs without level-shifting in 3.3V/5V systems. |
| UVLO Threshold | 2.65V (rising), 2.58V (falling) - prevents erratic switching during brown-out and supports safe hot-insertion into USB hosts. |
| FAULT Blanking Time | 6ms (typ) - eliminates false fault assertions during transient inrush or capacitive charging events. |
Pinout & Package
AP22652FDZ-7 is housed in a 2.0mm × 2.0mm, 0.65mm pitch W-DFN2020-6 (Type A1) package with exposed thermal pad connected to GND. Pin assignments are validated per Diodes DS41186 Rev. 5-2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Accepts 3.0–5.5V supply; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND | Ground Reference | Primary ground return and thermal path; must be connected to PCB exposed pad for thermal performance. |
| EN | Enable Control | Active-low digital input; drives internal gate driver when pulled low; leakage <±2µA ensures low-power control. |
| FAULT | Fault Reporting | Open-drain output asserted low during overcurrent, overtemperature, or reverse-voltage; 6ms deglitch built-in. |
| ILIM | Current-Limit Programming | Analog input sourcing current to set ILIMIT; supports 10kΩ–210kΩ resistor with validated polynomial calibration. |
| OUT | Switched Output | High-side switched output; requires ≥0.1µF bypass + ≥10µF bulk capacitance per USB spec near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Limit | 125–2665mA range with ±7% accuracy at 1.735A - enables precise matching to load requirements and avoids upstream supply collapse. |
| Constant-Current Mode | Maintains stable output current during overload without latch-off - allows graceful recovery after transient faults in USB host ports. |
| Reverse-Current Blocking | Blocks >0.32A reverse current when VOUT > VIN - meets USB specification prohibiting backfeed into host ports. |
| Soft-Start Rise Time | 0.5ms typical - limits inrush current into large output capacitors (e.g., 120µF USB requirement) without external components. |
| Thermal Protection | +145°C shutdown with +40°C hysteresis - prevents permanent damage during sustained short-circuit and enables automatic recovery. |
Applications
| USB 3.0/3.1 Type-A Port Protection | LCD Monitor Power Distribution |
|---|---|
|
Use Scenario: Hot-plug insertion of USB peripherals into desktop or docking station ports with 120µF output capacitance. IC Role / Device Role / Timing Role: High-side power switch providing inrush control, short-circuit limiting, and reverse-current blocking during plug-in events.

IC Role / Device Role / Timing Role: Precision current-limited switch protecting individual 5V domains against ESD-induced latch-up or cable shorts. Use Value: Delivers ±10% current-limit accuracy at high thresholds (e.g., 2.665A) to avoid nuisance tripping while ensuring compliance with IEC61000-4-2 (15kV contact discharge). |
Use Scenario: USB hub power control in cable/satellite STBs supporting external storage and streaming dongles. IC Role / Device Role / Timing Role: Hot-swap controller with 6ms FAULT deglitch and UVLO to maintain stable operation during intermittent cable disconnects.

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 |
|---|---|---|---|
| AP22652W-7 | Same die, SOT26 (Type A1) package - higher θJA (120°C/W) vs. W-DFN2020-6 (95°C/W); RDS(ON) identical but thermal derating starts earlier. | Preferred where board space permits larger footprint and thermal vias are limited; less suitable for dense USB-C modules. | Select for legacy SMT lines compatible with SOT26; verify thermal margin at 2.1A in ambient >60°C. |
| TCK107AG,TL | Toshiba part offers 2.5A max, active-high EN, and 1.5ms rise time - lacks reverse-current limiting and IEC61000-4-2 certification. | Used in industrial USB hubs where reverse-blocking is not required and ESD rating is managed at system level. | Choose only if active-high EN aligns with host logic and system-level ESD protection is already implemented. |
Compared with AP22652W-7, AP22652FDZ-7 delivers superior thermal performance in compact layouts and native USB-compliant reverse-current blocking; versus TCK107AG,TL, it provides certified 15kV ESD immunity and integrated deglitch - reducing validation effort for consumer electronics.

FAQ
What is the minimum recommended RLIM value for AP22652FDZ-7 to achieve 2.1A current limit?
The datasheet specifies RLIM = 10kΩ yields ILIMIT_Typ = 2665mA at +25°C. At -40°C to +85°C, the guaranteed minimum is 2398mA - meeting the 2.1A requirement. Using 10kΩ (1% tolerance) ensures design margin across temperature and process variation without exceeding maximum current capability.
Does AP22652FDZ-7 support reverse-voltage protection when the output is biased above input?
Yes. The device incorporates a reverse-voltage comparator with 65mV trip point (VOUT – VIN). When triggered, it disables the MOSFET within 2–20ms and asserts FAULT, preventing reverse current flow exceeding 0.32A - satisfying USB specification requirements for backfeed prevention.
Can AP22652FDZ-7 be used without an external ILIM resistor?
No. ILIM requires an external resistor (10kΩ–210kΩ) to set current limit. Leaving ILIM floating or shorted to GND results in undefined or excessively low current limits (e.g., 40–120mA). A 10kΩ resistor is mandatory for 2.1A operation and must be placed with minimal trace length to preserve accuracy.
How does the FAULT pin behave during thermal shutdown?
During thermal shutdown (>+145°C), FAULT is actively pulled low (VOL ≤180mV at 1mA sink) and remains asserted until junction temperature falls below +105°C (145°C – 40°C hysteresis). This provides unambiguous fault indication to host controllers without requiring external debouncing circuitry.
