Product details
Overview
AP22653AW6-7 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 AP22653AW6-7 datasheet, AP22653AW6-7 pinout, AP22653AW6-7 application, or AP22653AW6-7 equivalent, key selection criteria include its latch-off fault response (AP22653A variant), 5µs short-circuit detection, 0.5ms typical rise time with soft-start, and compatibility with 3.0–5.5V input rails in space-constrained USB power delivery paths.
Technical Context
The AP22653A implements a latch-off shutdown mechanism upon overcurrent or reverse-voltage events - unlike the constant-current limiting of AP22653 - requiring enable toggle or power cycle to recover. Its internal sense-FET-based current monitoring eliminates series resistance penalties while enabling fast 5µs fault detection and 6ms deglitched FAULT reporting.
Thermal protection activates at +145°C junction temperature with +40°C hysteresis, and reverse-voltage protection triggers at 65mV differential (VOUT – VIN), clamping reverse current to ≤0.32A. The device integrates output discharge (600Ω typical) and operates across –40°C to +85°C ambient with 125°C max junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit Range | 125mA to 2665mA (typ), set by external RLIM (10–210kΩ); enables precise USB port current budgeting |
| Current Limit Accuracy | ±7% at 1.735A (RLIM = 15kΩ); ensures predictable trip point without calibration |
| Short-Circuit Response | 5µs (typ); limits energy dissipation during fault and prevents upstream supply collapse |
| RDS(ON) | 65–90mΩ (TJ = +25°C, VIN = 5V); minimizes conduction loss and self-heating under 2.1A load |
| Fault Reporting | Active-low open-drain FAULT with 6ms deglitch; eliminates false trips from transient surges |
| Enable Logic | Active-high EN; simplifies interface with 3.3V/5V microcontrollers and USB host controllers |
| Input Voltage Range | 3.0V to 5.5V; matches standard USB 2.0/3.0 VBUS and industrial 3.3V/5V rails |
Pinout & Package
AP22653AW6-7 uses the W-DFN2020-6 (Type A1) package - 2.0mm × 2.0mm, 0.65mm pitch, exposed thermal pad - optimized for low-inductance, high-power-density USB port protection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Connects to 3.0–5.5V source; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin |
| GND | Ground Reference | Common return path; must be connected to PCB ground plane and exposed thermal pad |
| EN | Enable Input | Active-high logic control; drives high (>1.5V) to turn on switch; leakage <±2µA |
| FAULT | Fault Flag Output | Open-drain, active-low signal asserted during overcurrent, overtemperature, or reverse-voltage faults |
| ILIM | Current-Limit Programming | Sinks current proportional to RLIM value; sets ILIMIT per ILIMIT = 30321/RLIM1.055 mA |
| OUT | Switched Output | Delivers protected power to load; requires ≥10µF bulk capacitance (USB spec) and local 0.1µF bypass |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off Fault Recovery | AP22653A permanently disables output until EN toggled or VIN cycled - prevents uncontrolled restart after sustained overload |
| Reverse-Current Blocking | Blocks backflow from OUT to IN when disabled; limits reverse current to ≤0.32A if VOUT > VIN by ≥150mV |
| Controlled Soft-Start | 0.5ms typical output rise time (VIN = 5.5V, CL = 1µF); eliminates inrush current into large capacitive loads |
| Integrated Discharge Path | 600Ω internal discharge resistor activated on disable; safely drains output capacitance without external components |
| Robust ESD Protection | 15kV IEC61000-4-2 (with external cap), 2kV HBM, 500V CDM - meets USB system-level surge immunity requirements |

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 |
|---|---|---|---|
| AP22653W6-7 | Non-latch-off variant (constant-current limiting during overcurrent); same package and pinout | Suitable where automatic recovery after fault clearance is required (e.g., non-critical peripheral ports) | Select AP22653W6-7 if system firmware handles fault recovery and avoids manual reset. |
| TCK107AG,TL | Active-high enable, 2.5A rating, ±12% current limit accuracy, no reverse-current limiting | Lacks reverse-voltage comparator and reverse-current blocking; requires external diode for backfeed prevention | Choose TCK107AG,TL only when reverse protection is handled externally and higher current margin is prioritized over accuracy. |
Compared with AP22653W6-7, the AP22653AW6-7 adds fail-safe latch-off behavior critical for USB host isolation; versus TCK107AG,TL, it provides tighter current accuracy, integrated reverse-current blocking, and superior ESD robustness - making it optimal for certified USB endpoint designs.

FAQ
What is the function of the ILIM pin on AP22653AW6-7?
The ILIM pin sources current proportional to the programmed current-limit threshold. Connecting an external resistor (RLIM = 10–210kΩ) between ILIM and GND sets the output current limit per the equation ILIMIT_Typ[mA] = 30321/R[kΩ]1.055. Accuracy is ±7% at 1.735A (RLIM = 15kΩ), and trace routing must be short to minimize parasitic effects on accuracy.
How does the latch-off behavior differ from constant-current limiting in AP22653AW6-7?
AP22653AW6-7 latches off permanently during overcurrent or reverse-voltage faults - output remains disabled until EN is toggled or VIN is cycled. In contrast, AP22653 maintains constant-current limiting (clamping IOUT at ILIMIT) until thermal shutdown occurs. This makes AP22653AW6-7 ideal for safety-critical isolation where automatic recovery is undesirable.
Can AP22653AW6-7 be used in USB-C applications requiring 3A current capability?
No - AP22653AW6-7 is rated for up to 2.1A continuous load current and is specified for USB 2.0/3.0 (not USB-C PD) applications. Its current-limit range (125–2665mA) and RDS(ON) (65–90mΩ) are optimized for 5V/2.1A operation. For USB-C 3A+ use cases, a higher-current switch with appropriate thermal design and PD controller coordination is required.
What is the purpose of the FAULT pin's 6ms deglitch capability?
The FAULT pin incorporates a 6ms internal deglitch timer to suppress transient overcurrent events (e.g., capacitive inrush, brief load spikes) that could falsely trigger fault reporting. This eliminates need for external RC filtering while ensuring only sustained faults - exceeding 6ms - assert the open-drain FAULT signal, improving system reliability in noisy or dynamic load environments.
