Product details

Overview

AP22653AFDZ-7 from Diodes Incorporated is a single-channel, precision-adjustable, current-limited high-side power switch in W-DFN2020-6 (Type A1) package, featuring active-high enable, latch-off overcurrent response, 125–2665 mA programmable current limit via external resistor (RLIM), ±10% accuracy at high thresholds, and 5 µs typical short-circuit response time. It delivers robust protection for USB-compliant hot-swap ports in laptops and residential gateways.

For engineers reviewing the AP22653AFDZ-7 datasheet, AP22653AFDZ-7 pinout, AP22653AFDZ-7 application, or AP22653AFDZ-7 equivalent, key selection criteria include latch-off behavior under reverse-voltage/overcurrent, 6 ms deglitch on FAULT output, reverse-current blocking during shutdown, 3.0–5.5 V operating range, and thermal shutdown at +145°C with +40°C hysteresis.

Technical Context

The AP22653AFDZ-7 implements a precision current-sense FET architecture with external RLIM-based threshold programming, enabling accurate DC current limiting without series resistive loss. Its internal deglitch circuit suppresses false FAULT assertions for up to 6 ms, eliminating need for external RC filtering.

Unlike constant-current variants (AP22653), this A-suffix version latches off upon overcurrent or reverse-voltage detection-requiring EN toggle or power cycle for recovery. Protection includes UVLO (2.65 V trip, 65 mV hysteresis), reverse-voltage comparator (65 mV trip), and thermal shutdown with hysteresis, all integrated into a single monolithic die.

Key Specifications

Parameter	Value and Actual Design Meaning
Current-Limit Range	125–2665 mA (typ), set by 10–210 kΩ external RLIM resistor; enables precise load tailoring without redesign.
Overcurrent Response	Latch-off (not auto-retry); prevents repeated fault cycling in persistent short-circuit conditions.
FAULT Output	Active-low open-drain with 6 ms deglitch; asserts during overcurrent, overtemperature, or reverse-voltage-no external components needed.
Input Voltage Range	3.0–5.5 V; supports standard USB 2.0/3.0 VBUS rails and 3.3 V/5 V system domains.
R_DS(ON)	65–135 mΩ (max @ −40°C to +85°C); minimizes conduction loss and self-heating under 2.1 A continuous load.
Short-Circuit Response	5 µs (typ); limits energy dissipation during fault onset, enhancing system-level reliability.
Reverse Current Blocking	Blocks backflow from OUT to IN when disabled; critical for USB compliance and preventing bus corruption.

Pinout & Package

AP22653AFDZ-7 uses the W-DFN2020-6 (Type A1) package: 2.0 mm × 2.0 mm, 0.65 mm pitch, exposed thermal pad connected to GND externally for improved power dissipation.

Pin/Terminal	Circuit Role	Design Meaning
IN	Power Input	Connects to 3.0–5.5 V supply; requires ≥0.1 µF ceramic decoupling capacitor placed adjacent to pin.
GND	Ground Reference	Common return path; must be tied to exposed pad for thermal and electrical integrity.
EN	Enable Input	Active-high logic control; drives internal driver when pulled ≥1.5 V_IN; leakage <±2 µA ensures low-power disable state.
FAULT	Fault Indicator	Open-drain output asserted low during overcurrent, overtemperature, or reverse-voltage; sink capability up to 25 mA.
ILIM	Current-Limit Programming	Sources current proportional to RLIM value; sets ILIMIT per ILIMIT_Typ = 30321/R[kΩ]^1.055 (mA).
OUT	Switched Output	Drives load; requires ≥0.1 µF bypass + ≥10 µF bulk capacitance (USB spec); reverse-current limited to 0.32 A max.

Key Features

Feature	Design Value
Latch-off Overcurrent Protection	Shuts down permanently until EN toggled or VIN cycled-prevents thermal runaway in sustained faults.
Reverse-Voltage Detection	Triggers at 65 mV differential (V_OUT − V_IN); blocks reverse current and asserts FAULT within 2–20 ms.
Built-in Soft-Start	0.5 ms typical rise time; eliminates inrush surges into large capacitive loads (e.g., 120 µF USB outputs).
UVLO with Hysteresis	Turns off below 2.65 V (rising), re-enables only after >65 mV hysteresis-ensures clean hot-plug sequencing.
ESD Robustness	15 kV IEC61000-4-2 contact discharge (with external cap); 2 kV HBM; supports handling in uncontrolled environments.

Applications

USB 3.0 Hub Port Protection

Laptop USB-C Docking Station

Use Scenario: Protecting individual downstream USB 3.0 ports against short circuits, hot-plug inrush, and reverse current from peripheral devices.

IC Role / Device Role / Timing Role: High-side power switch with latch-off fault response and 6 ms deglitched FAULT reporting.

Use Value: Ensures USB compliance by blocking reverse current and limiting port current to ≤900 mA (via RLIM = 21.5 kΩ), preventing host controller damage.

Use Scenario: Power switching for USB-C alternate mode peripherals (e.g., DisplayPort, PCIe) in multi-function docking stations.

IC Role / Device Role / Timing Role: Precision current-limited enable switch with thermal shutdown at +145°C and +40°C hysteresis.

Use Value: Sustains 2.1 A continuous load while rejecting transient overloads-enabling reliable operation across varying ambient temperatures (−40°C to +85°C).

Residential Gateway PoE+ Interface

Industrial LCD Monitor Power Rail

Use Scenario: Isolating and protecting 5 V auxiliary rails powered from PoE+ midspan injectors in home gateways.

IC Role / Device Role / Timing Role: Reverse-current blocking switch with UVLO (2.65 V) and fast 5 µs short-circuit detection.

Use Value: Prevents backfeed into PoE circuitry during brownout or cable disconnect-maintaining IEEE 802.3at integrity.

Use Scenario: Enabling/disabling backlight or TCON power rails in industrial-grade LCD monitors subject to ESD and thermal stress.

IC Role / Device Role / Timing Role: Latch-off protected power switch with 15 kV IEC61000-4-2 ESD rating and exposed-pad thermal management.

Use Value: Eliminates need for discrete TVS and current-sense resistors-reducing BOM count and PCB area in space-constrained displays.

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
AP22653FDZ-7	No latch-off; maintains constant-current limiting during overcurrent instead of shutting down.	Suitable for applications requiring uninterrupted operation under transient overload (e.g., motor startup).	Select AP22653FDZ-7 if fault recovery without reset is required; AP22653AFDZ-7 preferred for safety-critical latch-down behavior.
TCK107AG,TL	Lower max current (1.5 A), no reverse-voltage detection, 10 µs short-circuit response, different enable polarity (active-low).	Targeted at cost-sensitive consumer electronics with less stringent USB reverse-current requirements.	Choose TCK107AG,TL only if 1.5 A rating suffices and latch-off is not mandated-AP22653AFDZ-7 offers superior protection granularity.

Compared with AP22653FDZ-7 and TCK107AG,TL, AP22653AFDZ-7 uniquely combines latch-off response, 65 mV reverse-voltage trip, and 15 kV IEC61000-4-2 ESD rating-making it optimal for USB-compliant, safety-audited designs where fault containment is non-negotiable.

FAQ

What is the minimum RLIM value that ensures 1.735 A current limit with ±7% accuracy?

The datasheet specifies ±7% accuracy at 1.735 A when RLIM = 15 kΩ. This value is validated across temperature (−40°C to +85°C) and process variation. Using 1% tolerance metal-film resistors and routing ILIM traces short and away from noise sources ensures this accuracy is maintained in production layouts.

Does AP22653AFDZ-7 require external components for FAULT debouncing?

No. The FAULT output includes an integrated 6 ms deglitch circuit that filters transient overcurrent events without external RC networks. This eliminates board space and component count while ensuring reliable fault reporting in noisy environments such as USB hubs with multiple concurrent plug/unplug events.

How does reverse-current limiting differ from reverse-current blocking in this device?

Reverse-current blocking occurs when the device is disabled (EN low), preventing any backflow from OUT to IN. Reverse-current limiting activates when enabled and V_OUT exceeds V_IN by >65 mV-clamping reverse current to ≤0.32 A to protect upstream sources while maintaining functional continuity.

Can AP22653AFDZ-7 operate reliably at 85°C ambient with 2.1 A load?

Yes. With W-DFN2020-6 package and proper PCB copper pour on the exposed pad, thermal resistance θ_JA is 95°C/W. At 2.1 A and R_DS(ON) = 135 mΩ, power dissipation is ~595 mW, resulting in ~57°C junction rise-well below the +125°C max operating junction temperature and +145°C thermal shutdown threshold.
