Product details
Overview
AP2311M8G-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, 2µs short-circuit response time, integrated output discharge, and operates across 2.7V–5.5V input range. It is deployed in USB-powered peripherals requiring robust over-current, over-temperature, and reverse-current protection.
For engineers reviewing the AP2311M8G-13 datasheet, AP2311M8G-13 pinout, AP2311M8G-13 application, or AP2311M8G-13 equivalent, key selection considerations include enable polarity (active-high), thermal shutdown threshold (+140°C), 7ms FLG deglitch timing, SO-8/MSOP-8/U-DFN package compatibility, and compliance with USB power delivery robustness requirements.
Technical Context
The AP2311M8G-13 integrates a P-channel MOSFET high-side switch with precision current sensing, enabling fast 2µs fault detection without external components. Its internal UVLO (2.0V typ) prevents turn-on during brown-out, while built-in soft-start yields 0.6ms typical output rise time to limit inrush.
It implements dual-protection coordination: current limiting clamps output at 2.5A (typ) under overload, and thermal shutdown activates at +140°C with +20°C hysteresis. The open-drain FLG pin reports faults after 7ms deglitching, and the N-MOS discharge transistor actively pulls OUT to GND when disabled-critical for controlled capacitive load discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical - maintains safe output current during sustained overload or short circuit without device damage |
| RDS(ON) | 70mΩ max at 5V, +25°C - minimizes conduction loss and self-heating under 2A load |
| Short-Circuit Response | 2µs - enables rapid current limiting before energy dissipation exceeds safe SOA limits |
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0/3.0 bus voltage range and 3.3V/5V system rails |
| Enable Polarity | Active-high - simplifies interface with microcontroller GPIOs without level-shifting or inversion logic |
| FLG Blanking Time | 7ms typical - suppresses false fault reporting during capacitive load turn-on transients |
| Discharge Resistance | 100Ω typical - ensures controlled VOUT decay (<0.6ms to <0.5V) when disabled |
| Thermal Shutdown | +140°C trip, +20°C hysteresis - provides autonomous recovery cycling during prolonged fault conditions |
Pinout & Package
AP2311M8G-13 is housed in an MSOP-8 package (3.0mm × 3.0mm × 1.0mm, 0.65mm pitch) with exposed thermal pad. The package supports enhanced thermal performance via PCB thermal vias to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; must be low-impedance connection to PCB ground plane |
| IN | Power input | Accepts 2.7V–5.5V supply; requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin |
| EN | Enable control | Active-high digital input; drives internal driver stage; logic high ≥2V enables switch |
| FLG | Fault indicator | Open-drain output asserted low during over-current or over-temperature; includes 7ms deglitch |
| OUT | Switched output | Delivers regulated power to load; all OUT pins tied internally and externally for parallel current handling |
| NC | No connect | Internally unconnected; recommended to tie externally to OUT for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 100Ω discharge path reduces VOUT to <0.5V in ≤0.6ms when disabled-eliminates need for external bleed resistor |
| Fast Short-Circuit Protection | 2µs response isolates fault before peak current exceeds safe SOA, preventing latch-up or bond-wire fusing |
| UVLO with Hysteresis | 2.0V turn-on threshold with 50mV hysteresis prevents oscillation during input ramp-up or brown-out |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled-critical for multi-rail systems and battery backup paths |
| Green RoHS Compliance | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); fully lead-free per EU RoHS 2011/65/EU |
Applications
| USB Hub Power Management | LCD Monitor Port Protection |

IC Role / Device Role / Timing Role: Load switch with controlled rise/fall times and output discharge during sleep mode exit. Use Value: Eliminates display flicker on wake by ensuring clean VOUT ramp and residual charge removal. |
| Set-Top Box USB Peripherals | Industrial Docking Station |
|
Use Scenario: Power gating USB peripherals (e.g., Wi-Fi dongles, storage) in residential gateways with thermal constraints. IC Role / Device Role / Timing Role: Thermally protected power switch with auto-recovery from over-temperature events. Use Value: Enables continuous operation under ambient +85°C with +140°C shutdown and +20°C hysteresis. |

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 |
|---|---|---|---|
| AP2301M8G-13 | Active-low enable; identical RDS(ON), current limit, and protection features | Requires inverted control signal; unsuitable where MCU GPIO is constrained to active-high drive only | Select when system logic naturally provides low-active enable or level-shifting is already present |
| TCK112G,115 (Nexperia) | 2.7A current limit; 50mΩ RDS(ON); no integrated discharge; 10ms FLG blanking | Lacks output discharge function; requires external RC network for controlled VOUT decay | Choose for lower conduction loss where discharge is handled externally or unnecessary |
Compared with AP2301M8G-13, the AP2311M8G-13 eliminates need for external inverters in active-high control systems; versus TCK112G,115, it trades marginally higher RDS(ON) for integrated discharge and tighter FLG timing-reducing BOM count and layout complexity in USB-compliant designs.

FAQ
What is the maximum continuous load current supported by AP2311M8G-13?
The AP2311M8G-13 supports 2.0A maximum continuous load current under recommended operating conditions (TA ≤ +85°C, proper PCB thermal design). Its 2.5A typical current limit provides headroom for transient surges without triggering thermal shutdown.
Does AP2311M8G-13 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, and a pull-up/pull-down on EN may be needed depending on MCU drive strength-but no resistors, capacitors, or diodes are needed for current limiting, discharge, or FLG reporting.
How does the output discharge function operate, and when is it active?
The discharge function activates automatically when EN is de-asserted (low) or during power-up/power-down when VIN falls below UVLO. An internal 100Ω N-MOS transistor connects OUT to GND, discharging external capacitors to <0.5V in ≤0.6ms-ensuring safe downstream power sequencing.
Can AP2311M8G-13 be used in dual-purpose ports like USB-C with data and power sharing?
No. Its integrated discharge function continuously drains connected batteries when disabled, risking overstress in dual-purpose ports (e.g., HDMI/MHL). Diodes explicitly advises against use in such configurations due to uncontrolled discharge and potential MOSFET overstress under constant output voltage bias.
