Product details
Overview
AP22653W6-7 from Diodes Incorporated is a single-channel, precision-adjustable, current-limited high-side power switch in W-DFN2020-6 (Type A1) package, designed for USB-compliant hot-swap applications. It delivers up to 2.1A continuous load current, features active-high enable, programmable current limit (125–2665mA via external resistor), ±7% accuracy at 1.735A (RLIM = 15kΩ), and integrated reverse-current blocking, overcurrent, overtemperature, short-circuit, and UVLO protection.
For engineers reviewing the AP22653W6-7 datasheet, AP22653W6-7 pinout, AP22653W6-7 application, or AP22653W6-7 equivalent, this device is selected for precision current-limiting power distribution in space-constrained USB ports, set-top boxes, and residential gateways where controlled turn-on, fault reporting, and latch-off-free constant-current behavior are required.
Technical Context
The AP22653 implements a MOSFET-based high-side switch with slew-rate-controlled gate driver, enabling soft-start (0.5ms typical rise time) and minimizing inrush surges into heavy capacitive loads. Its current-limit threshold is set by an external resistor on the ILIM pin, with real-time sensing via internal current-mirror FET - eliminating series sense resistors and preserving efficiency.
It integrates deglitched open-drain FAULT reporting (6ms blanking), reverse-voltage detection (65mV trip), reverse-current limiting (0.32A at 150mV), and thermal shutdown at +145°C with +40°C hysteresis. Unlike latch-off variants (AP22653A), the AP22653 maintains constant-current limiting during overloads without auto-shutdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Continuous Load Current | 2.1A - supports full USB PD-compatible downstream loads without derating at TA ≤ +85°C. |
| Current-Limit Range | 125mA to 2665mA (typ) - set externally via RLIM (10kΩ–210kΩ), enabling precise match to system-level fuse or upstream supply limits. |
| Current-Limit Accuracy | ±7% at 1.735A (RLIM = 15kΩ) - ensures reliable coordination with host controller current budgets and avoids nuisance tripping. |
| Rise/Fall Time | 0.5ms typical rise, 0.1–0.5ms fall - suppresses EMI and prevents bus voltage droop during hot-plug transitions. |
| Fault Response Time | 5µs typical short-circuit detection - enables rapid current clamping before trace fusing or connector damage occurs. |
| Input Voltage Range | 3.0V to 5.5V - compatible with standard USB 2.0/3.x VBUS and industrial 3.3V/5V rails. |
| Enable Logic | Active-High - simplifies direct interface with 3.3V/5V GPIOs without level-shifting or inverters. |
| Thermal Shutdown | +145°C with +40°C hysteresis - provides robust self-protection during sustained overload while preventing thermal oscillation. |
Pinout & Package
AP22653W6-7 is housed in a 2.0mm × 2.0mm, 0.65mm pitch W-DFN2020-6 (Type A1) package with exposed thermal pad connected internally to GND. The package supports high-power density PCB layouts and enhanced thermal dissipation (θJA = 95°C/W on JEDEC high-K board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 6) | Power Input | Connects to 3.0–5.5V source; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND (Pin 5) | Ground Reference | Primary ground return; must be connected to PCB ground plane and exposed thermal pad for thermal and electrical integrity. |
| EN (Pin 4) | Enable Control | Active-high logic input; drives internal gate driver when pulled ≥1.5VIN; leakage <±2µA ensures low-power disable state. |
| FAULT (Pin 3) | Fault Reporting | Open-drain, active-low output asserted during overcurrent, overtemperature, or reverse-voltage; includes 6ms deglitch to reject transient noise. |
| ILIM (Pin 2) | Current-Limit Programming | Current-source output setting threshold; accepts 10kΩ–210kΩ resistor to program ILIMIT with ±7% accuracy at mid-range. |
| OUT (Pin 1) | Switched Output | Drives load; requires ≥0.1µF bypass + ≥10µF bulk capacitance near pin per USB spec; reverse-current blocked when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Limit | 125–2665mA range with ±7% accuracy at 1.735A - enables exact matching to system-level current budgets without design margin overkill. |
| Constant-Current Overload Mode | Maintains regulated output current during overloads instead of latching off - preserves system uptime in transient fault conditions. |
| Reverse-Current Blocking & Limiting | Blocks reverse conduction when disabled; limits reverse current to 0.32A if VOUT > VIN by ≥65mV - satisfies USB reverse-current compliance. |
| Controlled Soft-Start | 0.5ms typical output rise time - eliminates inrush-induced voltage sag on shared VBUS rails and prevents false brownout resets. |
| Integrated Fault Protection | Single-chip coverage of overcurrent, short-circuit, overtemperature, reverse-voltage, and UVLO - reduces BOM count and layout complexity vs. discrete protection. |
| ESD Robustness | 2kV HBM, 500V CDM, and 15kV IEC61000-4-2 (with external cap) - ensures reliability in handling and end-equipment environments. |
Applications
| USB 3.x Port Power Switching | Set-Top Box Peripheral Power Control |

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 |
|---|---|---|---|
| AP22653W5-7 | SOT26 (Type A1) package - larger footprint (2.9mm × 2.8mm), higher θJA (120°C/W), same electrical specs. | Better suited for prototyping or legacy layouts where SOT26 is already routed; less optimal for ultra-dense USB Type-C modules. | Select when board space allows larger package and thermal margin is sufficient; avoid for new miniaturized designs targeting W-DFN2020-6. |
| TCK127G,CL | Toshiba part; active-high enable, 2.1A rating, but fixed 1.5A current limit (non-programmable); no reverse-current limiting. | Lacks ILIM programming and reverse-current protection - insufficient for USB compliance or flexible current budgeting. | Only consider if fixed 1.5A limit aligns exactly with system requirements and reverse-current blocking is handled elsewhere. |

FAQ
What is the minimum recommended RLIM value for AP22653W6-7, and why?
The minimum recommended RLIM is 10kΩ, corresponding to a typical current-limit threshold of 2665mA. Using lower resistance risks exceeding the device's maximum 2.1A continuous rating and may trigger thermal shutdown under sustained load. The datasheet specifies 10kΩ as the lower bound to ensure safe operation within absolute maximum ratings and maintain ±7% accuracy at mid-range settings.
Does AP22653W6-7 support reverse-voltage protection when disabled?
Yes - when disabled (EN low), AP22653W6-7 blocks reverse current flow from OUT to IN. When enabled, it actively limits reverse current to 0.32A if VOUT exceeds VIN by ≥65mV, satisfying USB specification requirements. This dual-mode reverse protection is implemented via internal comparator and current-limit circuitry, requiring no external components.
How does the FAULT pin behave during a short-circuit event?
During a short-circuit, the FAULT pin asserts low within 5µs (typical) and remains asserted as long as the fault persists. Its 6ms deglitch timer prevents false triggering from brief transients. Unlike latch-off variants, AP22653W6-7 does not shut down - it enters constant-current mode and continues regulating output current until the fault clears or thermal shutdown activates.
Can AP22653W6-7 be used in automotive applications?
No - AP22653W6-7 is rated for -40°C to +85°C ambient and is not qualified to AEC-Q100. For automotive use, Diodes offers the AP22653Q variant (separate datasheet), which meets automotive temperature range (-40°C to +125°C), qualification, and reliability requirements. Using AP22653W6-7 in automotive environments voids warranty and violates functional safety expectations.
