Product details
Overview
AP22811AW5-7 from Diodes Incorporated is a single-channel, current-limited, high-side power distribution load switch optimized for USB and hot-swap applications. It features 50 mΩ on-resistance, 2.7–5.5 V input range, integrated output discharge, reverse-current blocking, and auto-recovery over-current/short-circuit/over-temperature protection. It operates in SOT25 package and supports active-high enable (A version) for controlled power sequencing in portable computing systems.
For engineers reviewing the AP22811AW5-7 datasheet, AP22811AW5-7 pinout, AP22811AW5-7 application, or AP22811AW5-7 equivalent, key selection considerations include its 6 ms FLG deglitch timing, 0.6 ms typical rise time with soft-start, reverse-voltage trip at 50 mV, thermal shutdown at +140°C, and compliance with USB power delivery requirements in space-constrained designs.
Technical Context
The AP22811AW5-7 integrates an N-channel MOSFET with current-sense FET architecture-eliminating external sense resistors-and implements UVLO (2.0 V threshold, 180 mV hysteresis), thermal foldback, and reverse-voltage detection via differential comparator (25–75 mV trip). Its FLG pin uses internal deglitch logic to suppress false fault reporting during capacitive inrush.
It delivers controlled turn-on (tR = 2.1 ms typ.) and fast turn-off (tF = 0.65 ms typ.), supports up to 2 A continuous output current, and maintains reverse-current blocking (IREV ≤ 1 µA at VOUT = 5 V, VIN = 0 V) while enabling safe hot-plug operation into heavy capacitive loads (≥100 µF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - Supports full USB 2.0/3.0 bus voltage range and common 3.3 V/5 V system rails. |
| RDS(ON) | 50 mΩ typ. at VIN = 5 V, IOUT = 1 A - Limits conduction loss to ≤50 mW at 1 A, enabling thermally efficient operation in SOT25. |
| Over-Current Limit | 2.7 A typ. - Clamps sustained output current to prevent damage during overload without immediate shutdown. |
| FLG Blanking Time | 6 ms typ. - Suppresses transient inrush-induced false faults, eliminating need for external RC filtering. |
| Output Discharge Resistance | 90–130 Ω - Actively discharges output capacitance to <0.5 V within 0.4 ms when disabled, preventing floating rail issues. |
| Reverse-Voltage Trip | 50 mV typ. (VOUT – VIN) - Blocks reverse current before parasitic shoot-through occurs, protecting upstream sources. |
| Thermal Shutdown Threshold | +140 °C - Triggers automatic current-limit cycling to avoid permanent junction damage under sustained short-circuit. |
Pinout & Package
AP22811AW5-7 is housed in a RoHS-compliant, lead-free Green SOT25 (SC-74A) surface-mount package measuring 2.9 mm × 1.6 mm × 1.1 mm, optimized for thermal dissipation (RθJA = 123 °C/W) in compact PCB layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Switched output node; connects to load and ≥0.1 µF bypass + ≥10 µF bulk capacitor for USB stability. |
| 2 | GND | Power ground reference; must be low-inductance connection to minimize noise coupling and thermal resistance. |
| 3 | FLG | Open-drain fault flag; pulls low after 6 ms deglitch upon over-current or over-temperature event. |
| 4 | EN | Active-high enable input; requires ≥1.5 V logic high to activate switch; must not float. |
| 5 | IN | Input power rail; requires 1 µF ceramic bypass close to pin to suppress supply transients. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in Soft-Start | 0.6 ms typical rise time - Prevents inrush current spikes into large output capacitors (e.g., 120 µF SSD rails). |
| Integrated Output Discharge | Active discharge path (90–130 Ω) - Ensures rapid, controlled VOUT collapse to <0.5 V within 0.4 ms when disabled. |
| Reverse Current Blocking | 50 mV trip threshold with 6 ms delay - Stops backfeed from powered peripherals before MOSFET body diode conduction dominates. |
| Auto-Recovery Protection | Over-current, short-circuit, and over-temperature all recover automatically after fault removal - Eliminates manual reset requirement in embedded systems. |
| UVLO with Hysteresis | 2.0 V turn-on / 1.82 V turn-off - Prevents erratic switching near brown-out conditions in battery-powered USB ports. |
Applications

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 |
|---|---|---|---|
| TPS22915DBVR | Lower RDS(ON) (36 mΩ), no integrated discharge, 1.6–5.5 V input, open-drain FLG with 10 ms blanking. | Lacks output discharge function; requires external circuitry for VOUT collapse; better suited for non-hot-swap fixed-rail apps. | Select when lowest conduction loss is critical and discharge is handled externally or unnecessary. |
| RT9711CGQW | Higher RDS(ON) (85 mΩ), 2.5–5.5 V, no reverse-voltage protection, FLG with 12 ms blanking, no UVLO hysteresis. | Does not block reverse current or support USB-compliant hot-swap; limited thermal robustness (+125 °C shutdown). | Choose only for cost-sensitive, non-USB, low-capacitance applications where reverse feed is absent. |
Compared with TPS22915DBVR and RT9711CGQW, AP22811AW5-7 uniquely combines USB-optimized reverse-voltage blocking, integrated discharge, and 6 ms FLG blanking-making it the only option among the three qualified for hot-plug SSD and Ultrabook port designs requiring full fault autonomy.

FAQ
What is the maximum continuous output current rating for AP22811AW5-7?
The AP22811AW5-7 supports up to 2 A continuous output current under recommended operating conditions (TA ≤ +85°C, VIN = 2.7–5.5 V). Its over-current limit is 2.7 A typical, and short-circuit current is clamped to 300 mA, enabling safe operation into heavy capacitive loads without external current sensing.
Does AP22811AW5-7 require external components for basic operation?
No external components are required for core functionality: the device integrates soft-start, discharge, UVLO, and FLG deglitch. However, per datasheet guidelines, a 1 µF ceramic capacitor must be placed between IN and GND, and a 0.1 µF + ≥10 µF capacitor between OUT and GND to ensure stability, EMI control, and safe hot-plug behavior.
How does the FLG pin behave during a short-circuit event?
Upon detecting over-current or over-temperature, the FLG pin asserts low after a 6 ms deglitch timeout and remains low until both faults are cleared. During sustained short-circuit, the device cycles thermally (shut down → cool → restart), and FLG stays low throughout each cycle-providing unambiguous fault signaling to host controllers without pulse stretching or chatter.
Can AP22811AW5-7 be used in automotive applications?
The AP22811AW5-7 is not AEC-Q100 qualified and is specified for commercial temperature range (−40°C to +85°C). While it meets UL and CB safety certifications, Diodes Incorporated explicitly states that automotive-grade variants require separate qualification-contact Diodes directly for PPAP-capable, IATF 16949-manufactured alternatives.
