Product details
Overview
AP2311ASN-7 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 with 2.5A accurate current limiting, 70mΩ typical RDS(ON) at 5V, 2µs short-circuit response time, and integrated output discharge. It operates across 2.7V–5.5V input voltage and supports robust protection in LCD TV power rails and USB peripheral hubs.
For engineers reviewing the AP2311ASN-7 datasheet, AP2311ASN-7 pinout, AP2311ASN-7 application, or AP2311ASN-7 equivalent, this device is selected for its precise current limiting, fast fault detection, controlled rise time (0.6ms typ), reverse current blocking, and compact U-DFN2020-6 package - critical for space-constrained USB Type-C and embedded port power management designs.
Technical Context
The AP2311ASN-7 implements a P-channel MOSFET high-side switch with internal current-sense FET architecture, enabling accurate over-current detection without external sense resistors. Its thermal shutdown triggers at +140°C with +20°C hysteresis, and UVLO activates below 2.0V to prevent erratic turn-on during brownout.
It features an open-drain FLG output with 7ms deglitch timing to suppress false fault reporting during capacitive load transients, and an integrated N-MOS discharge path activated on disable - eliminating need for external bleed resistors in dual-purpose ports like HDMI/MHL charging interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical - clamps output current precisely during overload without external components |
| RDS(ON) | 70mΩ @ 5V, 25°C - minimizes conduction loss and self-heating in 2A load paths |
| Short-Circuit Response | 2µs - enables rapid current limiting before downstream component damage occurs |
| Input Voltage Range | 2.7V to 5.5V - matches USB 2.0/3.0 VBUS and 3.3V/5V system rail requirements |
| Rise Time | 0.6ms typical - controls inrush into 120µF loads, preventing supply droop and connector arcing |
| FLG Blanking Time | 7ms typical - suppresses false fault flags during hot-plug transients without external RC filters |
| Discharge Time | 0.6ms to <0.5V - safely drains output capacitance when disabled, avoiding backfeed in shared ports |
Pinout & Package
AP2311ASN-7 is housed in a 2.0mm × 2.0mm, 0.5mm pitch, 6-pin U-DFN2020-6 package with wettable flank leads and exposed thermal pad (connected to GND). The package supports reflow soldering and provides low θJA of 90°C/W on 1"×1" PCB with thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Primary supply connection; requires 0.1µF ceramic bypass capacitor placed adjacent to pin |
| EN | Enable Input | Active-high logic control; drives high (>2V) to enable switch; tied low to disable |
| OUT | Switched Output | High-side switched output; all OUT pins internally connected; drives load capacitance directly |
| GND | Ground Reference | System ground return; connects to exposed thermal pad for thermal performance |
| FLG | Fault Reporting | Open-drain, active-low flag; asserts after 7ms deglitch upon over-current or over-temperature |
| NC | No Internal Connection | Unbonded pad; recommended to tie externally to OUT for mechanical stability and EMI reduction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | Resistive N-MOS path discharges output to <0.5V in 0.6ms - eliminates need for external bleed resistor in USB/HDMI dual-mode ports |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled - essential for battery-backed or multi-rail systems |
| Controlled Rise/Fall Timing | 0.6ms rise / 0.05ms fall time - balances inrush suppression and fast turn-off for dynamic load switching |
| 7ms Fault Deglitch | Hardware-based blanking on FLG output - rejects transient spikes from hot-plug events without external filtering |
| Thermal Cycling Protection | +140°C shutdown with +20°C hysteresis - enables safe auto-recovery in sustained overload without latch-up |
Applications
| USB Peripheral Hubs | LCD Monitor Power Rails |
|---|---|

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 |
|---|---|---|---|
| AP2301ASN-7 | Active-low EN, identical RDS(ON), current limit, and package | Requires inverted enable logic; unsuitable where MCU GPIO is limited to active-high drive | Select when system-level enable signal is naturally active-low or buffered through inverter |
| TCK112G,LF | 2.8A current limit, 45mΩ RDS(ON), 1.8V–5.5V input, same U-DFN2020-6 | Lower on-resistance reduces thermal stress at 2A; lacks integrated discharge function | Choose when higher efficiency is prioritized and external discharge circuitry is acceptable |
Compared with AP2301ASN-7, the AP2311ASN-7 simplifies interface design with native active-high enable, while TCK112G offers lower conduction loss but requires external discharge components - making AP2311ASN-7 optimal for compact dual-mode ports where board area and BOM count are constrained.

FAQ
What is the maximum continuous load current supported by AP2311ASN-7?
The AP2311ASN-7 supports 2.0A maximum continuous load current per its Recommended Operating Conditions. Its 2.5A current limit is a protected trip threshold - not a sustained rating. Thermal derating applies above +85°C ambient; at 2A and 5V input, junction temperature remains within safe limits on standard 1"×1" PCB with thermal vias.
Does AP2311ASN-7 require external components for basic operation?
No external components are required for core functionality. A 0.1µF ceramic capacitor between IN and GND is mandatory for stability. The FLG output needs only a pull-up resistor if interfaced with a microcontroller. Discharge, UVLO, current limiting, and thermal protection are fully integrated - no external sense resistors, timers, or bleed circuits needed.
How does the FLG pin behave during a short-circuit event?
Upon short-circuit detection, the FLG pin remains inactive for 7ms (deglitch period), then pulls low and stays low until both over-current and over-temperature conditions clear. If the short persists, FLG stays asserted continuously. After fault removal, FLG returns high within 10µs - enabling immediate MCU polling without software debouncing.
Can AP2311ASN-7 be used in battery-powered applications?
Yes - its 0.1µA shutdown current (ISHDN) and 60µA quiescent current (IQ) make it suitable for battery-backed systems. When disabled, reverse current blocking prevents battery drain through the output. However, the integrated discharge function actively sinks current from VOUT during disable - ensure no critical backup capacitors are connected directly to OUT without isolation.
