Product details
Overview
AP22653FDZ-7 from Diodes Incorporated is a single-channel, precision-adjustable, current-limited high-side power switch optimized for USB-compliant hot-swap applications. It delivers up to 2.1A continuous load current, features programmable current-limit threshold (125–2665mA typ) via external resistor, ±10% current-limit accuracy at high settings, and fast 5µs short-circuit response time. It operates from 3.0V to 5.5V input and integrates reverse-current blocking, overtemperature shutdown, undervoltage lockout, and active-low open-drain FAULT reporting.
For engineers reviewing the AP22653FDZ-7 datasheet, AP22653FDZ-7 pinout, AP22653FDZ-7 application in USB power delivery or hot-plug systems, or AP22653FDZ-7 equivalent for current-limited load switching - this device provides precise, latch-off-free current limiting with controlled rise/fall times, integrated thermal protection, and IEC61000-4-2 Level 4 (15kV) ESD robustness on output terminals.
Technical Context
The AP22653FDZ-7 implements an active-high enable logic high-side MOSFET switch with internal gate driver slew-rate control to limit inrush current. Its current-limit circuitry uses a sense-FET architecture (not external shunt), enabling accurate DC current regulation without added series resistance in the power path.
It features dual-stage fault handling: immediate current clamping during overcurrent/short-circuit, followed by deglitched FAULT assertion (6ms blanking), and thermal shutdown at +145°C with +40°C hysteresis. Reverse-voltage detection triggers MOSFET turn-off when VOUT − VIN > 65mV, preventing backfeed into upstream sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Load Current | 2.1A continuous - supports USB PD sink loads and high-capacitance downstream rails without external current sensing. |
| Current-Limit Range | 125mA to 2665mA (typ) - set via 10kΩ–210kΩ external ILIM resistor; enables fine-grained protection tuning across diverse load profiles. |
| Current-Limit Accuracy | ±10% at high thresholds - ensures predictable trip behavior under worst-case process/temperature variation, critical for BOM margining. |
| Rise/Fall Time | 0.5ms typical rise time - soft-start prevents voltage droop and EMI spikes during hot-plug insertion of capacitive loads. |
| Short-Circuit Response | 5µs typical - limits energy dissipation during fault events, preserving MOSFET integrity and system stability. |
| Input Voltage Range | 3.0V to 5.5V - matches standard USB 2.0/3.x and 5V auxiliary rail requirements without level-shifting. |
| FAULT Output | Active-low open-drain with 6ms deglitch - eliminates false trips from transient surges; requires no external RC filter. |
Pinout & Package
AP22653FDZ-7 is housed in a W-DFN2020-6 (Type A1) 2.0mm × 2.0mm, 0.65mm pitch, thermally enhanced package with exposed pad connected to GND for improved power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Primary supply connection; requires ≥0.1µF ceramic decoupling capacitor placed adjacent to pin. |
| GND | Ground Reference | System ground return; connects internally to exposed pad - must be soldered to PCB ground plane for thermal performance. |
| EN | Enable Input | Active-high logic control; drives internal gate driver when pulled ≥1.5V (min VIH) relative to VIN. |
| ILIM | Current-Limit Programming | Sinks current proportional to desired ILIMIT; accepts 10kΩ–210kΩ resistor to GND for threshold setting. |
| FAULT | Fault Reporting | Open-drain output asserted low during overcurrent, overtemperature, or reverse-voltage conditions; blanked for 6ms post-fault. |
| OUT | Switched Output | High-side switched output; requires ≥10µF bulk capacitance per USB spec and local 0.1µF bypass near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Current Limit | 125–2665mA range via single external resistor - eliminates need for multiple fixed-limit parts or complex feedback loops. |
| Reverse-Current Blocking | Active MOSFET cutoff when VOUT > VIN - enforces USB compliance and prevents backfeed into host ports without diode loss. |
| Thermal Protection | +145°C shutdown with +40°C hysteresis - avoids oscillation during sustained overload and enables safe auto-recovery after cooling. |
| UVLO Threshold | 2.65V (typ) with 65mV hysteresis - ensures clean disable during brown-out and supports reliable hot-insertion sequencing. |
| ESD Robustness | 15kV IEC61000-4-2 contact discharge on OUT - protects against field-induced failures in consumer and industrial USB endpoints. |
Applications

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 |
|---|---|---|---|
| TPS22965DSGR | Fixed 2A current limit; no external ILIM programming; 1.2ms typical rise time; 3.5V–5.5V input range. | Lacks adjustable current threshold and reverse-current blocking; suited for cost-sensitive fixed-limit designs only. | Select when design requires minimal BOM count and fixed 2A protection without tuning. |
| AP22652FDZ-7 | Identical package and pinout; active-low EN instead of active-high; constant-current (non-latching) fault response. | Same USB hot-swap use cases but requires external logic inversion for EN control and tolerates temporary overloads without latching off. | Select when system firmware expects active-low enable signaling or prefers automatic recovery after brief overcurrent events. |
Compared with TPS22965DSGR, AP22653FDZ-7 offers programmable current limiting and reverse-current blocking essential for USB compliance; compared with AP22652FDZ-7, it simplifies enable interface integration and maintains identical protection behavior except for EN polarity.

FAQ
What is the function of the ILIM pin on AP22653FDZ-7?
The ILIM pin sinks a current proportional to the desired current-limit threshold. Connecting an external resistor (10kΩ–210kΩ) between ILIM and GND sets the output current limit from 125mA to 2665mA (typ). The relationship follows ILIMIT_Typ[mA] = 30321/R[kΩ]1.055, enabling precise, resistor-based tuning without feedback components.
Does AP22653FDZ-7 provide reverse-current blocking during shutdown?
Yes. When disabled (EN low), the internal MOSFET fully turns off, blocking reverse current flow from OUT to IN. During enable, it also actively limits reverse current to ≤0.32A if VOUT exceeds VIN by >65mV - satisfying USB specification requirements for backfeed prevention in both static and dynamic states.
How does the FAULT pin behave during a short-circuit event?
During short-circuit, FAULT asserts low within 5µs (typ), remains asserted for ≥6ms (deglitch window), then stays low until the fault clears and the device recovers. If the overload persists beyond thermal shutdown threshold (+145°C), FAULT stays low until junction cools by ~40°C and the device automatically resumes operation - no manual reset required.
Can AP22653FDZ-7 operate reliably at 85°C ambient temperature?
Yes. It is rated for -40°C to +85°C ambient operation with full 2.1A current capability in W-DFN2020-6 package. At +85°C, RDS(ON) rises to 135mΩ max, and current-limit accuracy remains within ±10% at high thresholds. Thermal derating is not required below +85°C ambient per datasheet specifications.
