Product details
Overview
AP22802AW5-7 from Diodes Incorporated is a single-channel, current-limited, high-side load switch optimized for USB and hot-swap applications. It features 50 mΩ RDS(ON) at 5 V, 2.7 A over-current limit, 0.7 µs short-circuit response time, integrated output discharge (90 Ω), and active-low open-drain FLG with 6 ms deglitch - deployed in ultrabooks and SSD power sequencing.
For engineers reviewing the AP22802AW5-7 datasheet, AP22802AW5-7 pinout, AP22802AW5-7 application, or AP22802AW5-7 equivalent, key selection criteria include enable polarity (active-high), thermal shutdown threshold (+140 °C), UVLO (2.0 V typ), reverse current blocking, and SOT25 footprint compatibility in space-constrained USB peripheral rails.
Technical Context
The AP22802AW5-7 implements a thermally protected N-channel MOSFET high-side switch with integrated current sensing via sense-FET architecture - eliminating external shunt resistors while maintaining low conduction loss. Its control logic includes UVLO (2.0 V rising), 6 ms FLG deglitch, and auto-recovery over-current/short-circuit protection.
It delivers controlled turn-on (2.1 ms typ rise time) and fast fault response (0.7 µs short-circuit detection), with built-in output discharge (0.4 ms to <0.5 V) and reverse current blocking (<1 µA leakage). The device operates across 2.7–5.5 V input and supports ambient temperatures from –40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 50 mΩ max at VIN = 5 V, IOUT = 2 A - enables low-power-loss switching in 2 A USB rail applications |
| Over-current limit | 2.7 A typ at VIN = 5 V - clamps output current during overload without latch-off, supporting auto-recovery |
| Short-circuit response | 0.7 µs typ - ensures rapid fault containment before system-level damage occurs |
| UVLO threshold | 2.0 V typ rising - prevents erratic turn-on during brown-out or hot-plug ramp-up |
| Discharge resistance | 90 Ω typ - fully discharges 1 µF output cap to <0.5 V in 0.4 ms, eliminating floating voltage on disable |
| FLG deglitch | 6 ms nominal - suppresses false fault reporting from capacitive inrush transients |
| Thermal shutdown | +140 °C trigger with +60 °C hysteresis - enables safe thermal cycling under sustained short-circuit conditions |
Pinout & Package
AP22802AW5-7 is housed in a RoHS-compliant, lead-free SOT25 package (9 mm² footprint, 1.6 mm × 2.8 mm × 1.3 mm), optimized for thermal dissipation (RθJA = 180 °C/W) and PCB area efficiency in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 OUT | Switched output node | Drives downstream load; supports reverse current blocking when disabled |
| 2 GND | Power and signal reference | Common return path for internal circuitry and thermal pad connection |
| 3 FLG | Open-drain fault indicator | Active-low flag asserted after 6 ms deglitch on over-current or over-temperature event |
| 4 EN | Enable control input | Active-high logic (AP22802A variant); requires ≥1.5 V to enable, ≤0.5 V to disable |
| 5 IN | Input power supply pin | Accepts 2.7–5.5 V; feeds internal regulator and power switch; requires 1 µF local ceramic bypass |
Key Features
| Feature | Design Value |
|---|---|
| Integrated output discharge | 90 Ω internal FET path discharges output caps to <0.5 V in 0.4 ms - eliminates need for external bleed resistor |
| Auto-recovery protection | Over-current, short-circuit, and over-temperature faults self-clear once condition resolves - no manual reset required |
| USB-compliant hot-swap | Meets USB power delivery timing and inrush control requirements with 2.1 ms controlled rise time and 0.7 µs fault detection |
| No external components needed | 6 ms FLG deglitch, UVLO, and discharge function are fully internal - reduces BOM count and layout complexity |
| Reverse current blocking | <1 µA leakage at VIN = 0 V, VOUT = 5 V - prevents backfeed from powered outputs into shut-down rails |
Applications
| Ultrabook Power Sequencing | SSD Power Enable |
|---|---|
|

IC Role / Device Role / Timing Role: Thermally robust high-side switch with +140 °C shutdown and +60 °C hysteresis for sustained operation. Use Value: Maintains reliability under repeated short-circuit events (e.g., cable shorts) without permanent latch-off or manual intervention. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22811W5-7 | Lower RDS(ON) (35 mΩ), higher ILIMIT (3.5 A), same SOT25 package and pinout | Targeted at higher-current USB PD 3.0 and PCIe Gen4 SSD rails requiring >2.5 A continuous delivery | Select when higher current capacity and lower conduction loss outweigh cost sensitivity; not drop-in due to different enable logic timing |
| TCK112G,LF | Active-high EN, 45 mΩ RDS(ON), 2.5 A limit, integrated soft-start (no FLG), different pinout (SOT-23-5) | Used in industrial IoT sensors where soft-start is prioritized over fault reporting and compactness is critical | Choose only if FLG monitoring is unnecessary and board layout allows rework for non-SOT25-compatible footprint |
Compared with AP22802AW5-7, AP22811W5-7 offers higher current capability and lower loss but lacks identical enable timing behavior, while TCK112G,LF trades fault visibility for soft-start simplicity and requires PCB redesign - making AP22802AW5-7 optimal for USB-compliant, FLG-monitored, cost-sensitive ultrabook and SSD applications.

FAQ
What is the enable polarity of AP22802AW5-7?
The "A" suffix denotes active-high enable: the device turns on when EN voltage exceeds 1.5 V (min) and turns off when EN falls below 0.5 V (max). This matches standard GPIO logic levels and eliminates need for level-shifting in most host MCU interfaces.
Does AP22802AW5-7 require external components for basic operation?
No external components are required for core functionality: UVLO, FLG deglitch, output discharge, and over-current protection are fully integrated. A 1 µF ceramic capacitor between IN and GND is recommended for stability, but no pull-up/down resistors, timing capacitors, or discharge resistors are needed.
How does the FLG pin behave during transient over-current events?
The FLG pin remains inactive during brief inrush or capacitive transients due to its 6 ms deglitch timeout. It asserts low only after sustained over-current or over-temperature conditions exceed this window - preventing false alarms during normal hot-plug or load switching.
Can AP22802AW5-7 be used in 3.3 V-only systems?
Yes: it operates across 2.7–5.5 V input range and maintains full specifications at 3.3 V, including 60 mΩ RDS(ON) (typ), 2.2 A over-current limit, and 2.1 ms rise time - making it suitable for low-voltage embedded USB and peripheral rails.
