Product details
Overview
AP22652AFDZ-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 ±7% current-limit accuracy at 1.735A (with 15kΩ ILIM resistor), provides latch-off overcurrent response, and integrates reverse-current blocking, thermal shutdown at +145°C, and 6ms deglitched FAULT reporting - deployed in residential gateways and LCD monitors.
For engineers reviewing the AP22652AFDZ-7 datasheet, AP22652AFDZ-7 pinout, AP22652AFDZ-7 application, or AP22652AFDZ-7 equivalent, this device is selected for precise programmable current limiting (125–2665mA), fast short-circuit response (5µs typ), controlled rise time (0.5ms typ), and latch-off fault behavior under sustained overload - critical for robust USB power delivery and capacitive-load management.
Technical Context
The AP22652AFDZ-7 implements a high-side N-channel MOSFET with integrated gate driver, slew-rate control, and current-sense FET-based limiting. Its latch-off behavior distinguishes it from constant-current variants (e.g., AP22652), triggering permanent shutdown after 6ms deglitch timeout during overcurrent or reverse-voltage events.
It operates across 3.0V–5.5V input range, includes undervoltage lockout (~2.65V trip), reverse-voltage comparator (65mV threshold), and thermal protection with +40°C hysteresis. The FAULT pin is open-drain active-low with blanking time, and ILIM sets current limit via external resistor (10kΩ–210kΩ).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Continuous Load Current | 2.1A - supports full USB PD-compatible loads without external current sensing. |
| Adjustable Current Limit Range | 125mA to 2665mA (typ) - set by external ILIM resistor; enables fine-grained system-level current budgeting. |
| Current-Limit Accuracy | ±7% at 1.735A (RLIM = 15kΩ) - ensures predictable trip point for safety-critical overcurrent protection. |
| Short-Circuit Response Time | 5µs (typ) - limits energy dissipation during hard shorts, preserving downstream components. |
| RDS(ON) | 65–90mΩ (TJ = +25°C) - minimizes conduction loss and self-heating at 2.1A (≤0.4W typical). |
| Fault Reporting | 6ms deglitched active-low open-drain FAULT - prevents false triggers from transient surges; no external RC needed. |
| Operating Temperature | −40°C to +85°C ambient - validated for consumer electronics enclosures without forced cooling. |
Pinout & Package
AP22652AFDZ-7 uses the W-DFN2020-6 (Type A1) thermally enhanced package with exposed pad connected to GND for improved power dissipation. Pin assignments are verified per Diodes DS41186 Rev. 5-2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Connects to 3.0–5.5V supply; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND | Ground Reference | System ground return; internal connection to exposed pad - must be soldered to PCB ground plane. |
| EN | Active-Low Enable | Logic low (≤0.4V) enables switch; high (>1.5V) disables output and activates discharge path (RDIS ≈ 600Ω). |
| FAULT | Open-Drain Fault Flag | Asserted low during overcurrent, overtemperature, or reverse-voltage; 6ms deglitch prevents bounce on transient faults. |
| ILIM | Current-Limit Programming | Sinks current proportional to desired limit; accepts 10kΩ–210kΩ resistor to set threshold from 125mA to 2665mA. |
| 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 Overcurrent Response | Permanently disables output after 6ms deglitched fault detection - eliminates retry loops in persistent short conditions. |
| Reverse-Current Blocking & Limiting | Blocks reverse flow when disabled; limits reverse current to ≤0.32A if VOUT − VIN = 150mV - meets USB reverse-current compliance. |
| Built-In Soft-Start | 0.5ms typical output rise time - suppresses inrush into large capacitive loads (e.g., 120µF USB outputs). |
| Thermal Protection with Hysteresis | Shuts down at +145°C junction temperature; re-enables only after cooling ≥40°C - prevents thermal oscillation. |
| ESD Robustness | 15kV IEC61000-4-2 contact discharge (with external capacitance); 2kV HBM - suitable for board-level handling in manufacturing. |
Applications
| USB Power Delivery Ports | LCD Monitor Power Rails |
|---|---|
|

Use Value: Survives sustained 2.1A overload due to antenna mismatch or RF amplifier fault - avoids system-wide brownout. |
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 |
|---|---|---|---|
| AP22652FDDZ-7 | Same package and pinout; active-low enable; constant-current (non-latching) overcurrent response. | Used where automatic recovery after transient overload is required (e.g., intermittent short circuits). | Select when system firmware expects periodic fault retries rather than hard latch-off. |
| TPS22965DSGR | TI part; 2.5A max; ±15% current limit accuracy; no reverse-current limiting; 1.2ms rise time. | Targeted at general-purpose hot-swap, not USB-specific reverse-current compliance. | Choose when higher current headroom is needed and reverse-current blocking is handled elsewhere. |
Compared with AP22652FDDZ-7, the AP22652AFDZ-7 adds latch-off for definitive fault isolation, while TPS22965DSGR trades precision and reverse-current capability for higher current rating - making AP22652AFDZ-7 optimal for USB-compliant, safety-critical, low-ESD-risk designs.

FAQ
What is the function of the ILIM pin on AP22652AFDZ-7?
The ILIM pin sources current proportional to the programmed current-limit threshold. An external resistor (10kΩ–210kΩ) between ILIM and GND sets the trip point from 125mA to 2665mA using the equation ILIMIT_Typ[mA] = 30321/R[kΩ]^1.055. Layout must minimize trace length to preserve accuracy against parasitic resistance.
How does the latch-off behavior differ from constant-current limiting in AP22652AFDZ-7?
Unlike constant-current switches (e.g., AP22652), AP22652AFDZ-7 enters irreversible shutdown after 6ms deglitched overcurrent detection. Recovery requires toggling EN or cycling VIN - preventing repeated fault stress during persistent shorts, which enhances system safety in unattended equipment.
Can AP22652AFDZ-7 be used in automotive applications?
No - AP22652AFDZ-7 is rated for −40°C to +85°C ambient and lacks AEC-Q100 qualification. Diodes offers the automotive-grade AP22653Q variant (separate datasheet) with extended temperature range and qualification for infotainment and body electronics.
What is the purpose of the exposed pad on the W-DFN2020-6 package?
The exposed pad is internally connected to GND and must be soldered to a PCB thermal pad tied to a solid ground plane. It reduces θJA to 95°C/W and enables 570mW power dissipation at +70°C ambient - critical for sustaining 2.1A loads without thermal derating in compact layouts.
