Product details
Overview
AP2311AS-13 from Diodes Incorporated is a single-channel, active-high enable, current-limited high-side power switch optimized for USB and hot-swap applications. It delivers 2.0A continuous load current, features 70mΩ typical RDS(ON) at 5V, integrates output discharge, reverse current blocking, and provides 2µs short-circuit response time. It operates across 2.7V–5.5V input voltage and supports SO-8 packaging for embedded power rail control in consumer electronics.
For engineers reviewing the AP2311AS-13 datasheet, AP2311AS-13 pinout, AP2311AS-13 application, or AP2311AS-13 equivalent, key selection considerations include enable polarity (active-high), thermal shutdown threshold (+140°C), UVLO hysteresis (50mV), FLG deglitch timing (7ms typ), and package-specific thermal resistance (96°C/W for SO-8).
Technical Context
The AP2311AS-13 implements a P-channel MOSFET high-side switch with integrated current-sense FET and thermal sensing circuitry. Its protection architecture combines fast over-current detection (2µs response), 7ms deglitched open-drain FLG reporting, and +140°C thermal shutdown with +20°C hysteresis - enabling robust fault recovery without external components.
It incorporates soft-start via built-in slew-rate control (0.6ms typical rise time), undervoltage lockout (2.0V turn-on threshold, 50mV hysteresis), and an N-MOS discharge transistor activated on disable to safely dissipate output capacitance energy. All functions operate autonomously without host MCU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 2.0A max - supports USB-compliant hot-swap loads without derating at TA ≤ +85°C |
| RDS(ON) | 70mΩ typ @ VIN=5V, IOUT=2A - limits conduction loss to <280mW at full load |
| Short-Circuit Response Time | 2µs - enables immediate current limiting before system-level damage occurs |
| FLG Blanking Time | 7ms typ - suppresses false fault reporting during capacitive inrush transients |
| UVLO Threshold | 2.0V rising, 1.95V falling - prevents erratic switching during brown-out or hot-plug ramp-up |
| Thermal Shutdown | +140°C trip, +120°C release - ensures safe cycling under sustained overload without latch-off |
| Output Discharge Resistance | 105Ω typ - discharges 1µF load to <0.5V in 0.6ms, eliminating floating output states |
Pinout & Package
AP2311AS-13 is supplied in SO-8 package with exposed pad (non-electrical ground connection, intended for thermal enhancement). Pin 1 = GND, Pin 2/3 = IN (tied externally), Pin 4 = EN (active-high), Pin 5 = FLG (open-drain fault flag), Pin 6/7 = OUT (tied externally), Pin 8 = NC (recommended tied to OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power Ground Reference | Primary return path for internal current sense and thermal sensor; must connect to low-impedance PCB ground plane |
| IN (Pins 2 & 3) | Input Voltage Supply | Dual-pin configuration requires external tie; accepts 2.7V–5.5V with mandatory 0.1µF ceramic bypass to GND |
| EN (Pin 4) | Enable Control Input | Active-high logic interface; drives internal driver only when ≥2V (VIH min); draws ≤1µA leakage |
| FLG (Pin 5) | Fault Reporting Output | Open-drain, active-low signal asserting after 7ms deglitch upon over-current or over-temperature event |
| OUT (Pins 6 & 7) | Switched Output Terminal | Dual-pin configuration requires external tie; delivers controlled power to load with integrated discharge path |
| NC (Pin 8) | No Internal Connection | Not bonded; recommended tied to OUT to minimize EMI and improve layout symmetry |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 105Ω discharge path automatically activates on disable, clearing residual VOUT without external FET or resistor |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled - eliminates need for external blocking diode in battery-backup paths |
| Autonomous Thermal Cycling | +140°C shutdown with +20°C hysteresis enables self-recovering operation under sustained short-circuit without host intervention |
| USB-Compliant Hot-Swap Timing | 0.6ms typical rise time and 2µs fault response meet USB 2.0/3.0 power delivery transient requirements |
| 7ms FLG Deglitch | Hardware-based blanking eliminates need for external RC filter or firmware debouncing of fault signals |

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 |
|---|---|---|---|
| AP2301AS-13 | Active-low EN pin; identical RDS(ON), current limit, and protection features | Requires inverted enable logic; otherwise drop-in compatible in SO-8 footprint and thermal profile | Select when system controller outputs active-low enable signals or shares enable net with legacy designs |
| TCK112G,LF | Lower 36mΩ RDS(ON) but rated for 1.5A only; no integrated discharge function | Suitable for lower-power USB devices but requires external discharge circuit for hot-swap compliance | Choose where lower conduction loss outweighs added BOM cost and board space for external discharge FET |
Compared with AP2301AS-13, the AP2311AS-13 simplifies enable logic integration in new designs using active-high microcontrollers, while TCK112G offers lower on-resistance at reduced current capability and missing autonomous discharge - making AP2311AS-13 optimal for USB-compliant hot-swap systems requiring minimal external components.

FAQ
What is the maximum continuous output current rating for AP2311AS-13 under standard SO-8 PCB conditions?
The AP2311AS-13 is rated for 2.0A continuous output current at TA ≤ +85°C when mounted on a 2"×2" FR-4 PCB with 2oz copper and minimum recommended pad layout. This rating assumes 96°C/W junction-to-ambient thermal resistance and accounts for self-heating at 70mΩ RDS(ON). Derating is required above +85°C ambient or with reduced copper area.
Does AP2311AS-13 require external components to implement its output discharge function?
No. The AP2311AS-13 integrates a dedicated N-MOS discharge transistor with 105Ω typical on-resistance. When the device is disabled (EN low), this path automatically activates to discharge external output capacitance - eliminating the need for external resistors, FETs, or timing components. Discharge completes in ≤0.6ms for a 1µF load.
How does the 7ms FLG deglitch timeout prevent false fault reporting during hot-plug events?
The 7ms deglitch circuit holds the FLG pin inactive until an over-current or over-temperature condition persists beyond 7ms. This filters out transient inrush currents caused by charging large output capacitors (e.g., 120µF in USB hubs) or brief short-circuits during connector mating - ensuring FLG only asserts for sustained faults requiring system-level action.
Can AP2311AS-13 be used in dual-purpose HDMI/MHL ports with simultaneous data and charging functions?
Yes. The AP2311AS-13 supports dual-purpose port applications by providing controlled power ramp-up before data link activation and automatic output discharge during standby. Its reverse current blocking prevents battery drain from VOUT to VIN, and its 2.0A rating accommodates combined data+charging loads - provided VIN reaches operating voltage prior to EN assertion.
