Product details
Overview
AP2311MPG-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 2.5A 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 AP2311MPG-13 datasheet, AP2311MPG-13 pinout, AP2311MPG-13 application, or AP2311MPG-13 equivalent, key selection criteria include enable polarity (active-high), thermal shutdown threshold (+140°C), FLG deglitch timing (7ms typ), soft-start rise time (0.6ms typ), and MSOP-8EP package with exposed thermal pad.
Technical Context
The AP2311MPG-13 implements a P-channel MOSFET high-side switch with embedded current-sense FET architecture-eliminating external sense resistors while maintaining low conduction loss. Its control logic integrates UVLO (2.0V trip, 50mV hysteresis), thermal shutdown (+140°C with +20°C hysteresis), and fault blanking to suppress transient over-current false triggers.
It features an N-channel discharge transistor activated only when disabled, providing a 100Ω typical discharge path to safely dissipate output capacitance energy. The open-drain FLG output reports combined over-current and over-temperature faults after 7ms deglitch, with 20Ω typical on-resistance and <1µA off-state leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical; clamps load current precisely during overload without latch-off, enabling safe recovery. |
| RDS(ON) | 70mΩ max at +25°C, VIN=5V; minimizes power loss and self-heating in 2A continuous operation. |
| Short-Circuit Response | 2µs; detects and limits output current before destructive energy accumulates in capacitive loads. |
| Input Voltage Range | 2.7V–5.5V; compatible with USB 2.0/3.0 bus voltages and single-cell Li-ion backup rails. |
| Enable Polarity | Active-high; simplifies interface with microcontroller GPIOs or system power sequencers requiring assert-on-enable logic. |
| FLG Blanking Time | 7ms typical; prevents false fault reporting during inrush or transient capacitive discharge events. |
| Thermal Shutdown | +140°C junction threshold with +20°C hysteresis; enables auto-recovery cycling under sustained overload. |
Pinout & Package
AP2311MPG-13 is packaged in MSOP-8EP (8-lead Mini Small Outline Package with Exposed Pad), offering enhanced thermal performance via soldered exposed pad connected to PCB ground plane. Thermal resistance θJA is 92°C/W under standard 2oz copper layout with thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; must be low-impedance connection to system 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, low ≤0.8V disables. |
| FLG | Fault indicator | Open-drain output asserted low during over-current or over-temperature; 7ms deglitch prevents bounce. |
| OUT | Switched output | Delivers regulated current to load; all OUT pins tied together internally; connects to downstream USB port or rail. |
| NC | No internal connection | Not bonded; recommended to tie externally to OUT for mechanical stability and EMI reduction. |
| Exposed Pad | Thermal & electrical ground | Must be soldered to PCB ground plane with ≥4 thermal vias; improves θJA by ~38% vs. non-EP variant. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 100Ω typical discharge resistance activates automatically on disable, eliminating external bleed resistors for USB hot-unplug safety. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled; critical for multi-rail systems sharing common grounds. |
| Built-in Soft-Start | 0.6ms typical output rise time limits inrush into 120µF+ loads, avoiding input rail collapse in set-top boxes. |
| UVLO with Hysteresis | 2.0V turn-on / 1.95V turn-off; ensures clean power-up sequencing and prevents erratic switching near brownout thresholds. |
| ESD Robustness | 2kV HBM / 200V MM; withstands handling and board assembly without additional protection circuitry. |
Applications
| USB Peripheral Hub Power Control | LCD TV Backlight Rail Switching |

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 |
|---|---|---|---|
| AP2301MPG-13 | Active-low enable; identical RDS(ON), current limit, and protection features. | Requires inverted logic drive; unsuitable where MCU GPIOs lack pull-down or level-shifting capability. | Select when system control logic natively supports active-low signaling and no level translation is desired. |
| TCK112G,LF | 2.2A current limit; 85mΩ RDS(ON); no integrated discharge; 10ms FLG blanking. | Lacks output discharge, requiring external circuitry for USB hot-unplug compliance. | Choose only if lower cost outweighs added design complexity and BOM overhead of external discharge FET/resistor. |
Compared with AP2301MPG-13, AP2311MPG-13 eliminates level-shifting needs in active-high control systems; versus TCK112G, it provides integrated discharge and tighter current accuracy-reducing total solution size and qualification effort for USB-compliant designs.

FAQ
What is the maximum continuous output current supported by AP2311MPG-13?
The AP2311MPG-13 supports 2.0A maximum continuous load current per its Recommended Operating Conditions. Its 2.5A current limit is a fault-clamping threshold-not a sustained rating-and thermal derating applies above +25°C ambient. At +85°C, RDS(ON) rises to 105mΩ, reducing practical continuous current to ~1.6A with standard MSOP-8EP layout.
Does AP2311MPG-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 the exposed pad must be soldered to ground. All protection, soft-start, discharge, and fault reporting functions are fully integrated-no external resistors, capacitors, or FETs needed for USB-compliant operation.
How does the FLG pin behave during thermal shutdown?
The FLG pin asserts low during both over-current and over-temperature events, with identical 7ms deglitch timing. During thermal cycling (e.g., sustained short-circuit), FLG remains low continuously while the device toggles between on/off states. It returns high only after both fault conditions clear and the die cools below the +120°C hysteresis threshold.
Can AP2311MPG-13 be used in automotive applications?
No. AP2311MPG-13 is specified for -40°C to +85°C ambient operation and lacks AEC-Q100 qualification, automotive-grade ESD (e.g., ISO 10605), or extended temperature range (-40°C to +125°C). Its thermal shutdown threshold (+140°C) and package construction are not validated for under-hood environments or automotive power supply transients.
