Product details
Overview
AP2511AMP-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 continuous load current with 3.7A typical current limiting, 70mΩ typical RDS(ON), 2µs short-circuit response time, and integrated output discharge. It operates across 2.7V–5.5V input voltage and supports LCD TVs, docking stations, and USB-powered peripherals.
For engineers reviewing the AP2511AMP-13 datasheet, AP2511AMP-13 pinout, AP2511AMP-13 application, or AP2511AMP-13 equivalent, this page provides verified functional role, thermal protection behavior, FLG fault reporting timing, and package-specific thermal resistance data - all critical for USB port power management design and BOM validation.
Technical Context
The AP2511AMP-13 implements a P-channel MOSFET high-side switch with embedded current-sense FET architecture, enabling accurate 3.7A current limiting without external sense resistors. Its UVLO (2.0V threshold) and 20°C thermal hysteresis ensure stable turn-on/turn-off sequencing during hot-plug events.
It integrates dual protection logic: fast 2µs short-circuit detection triggers current-limiting mode before thermal shutdown, while the 7ms deglitched open-drain FLG output reports overcurrent or overtemperature faults only after sustained violation - eliminating false trips from capacitive inrush.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 3.7A typical - clamps output current to prevent damage during sustained overload or short circuit. |
| RDS(ON) | 70mΩ typical at 5V/25°C - minimizes conduction loss and self-heating under 2.5A continuous load. |
| Short-Circuit Response | 2µs - enables rapid current limiting before energy dissipation risks MOSFET failure. |
| FLG Blanking Time | 7ms typical - suppresses false fault reporting during output capacitor charging transients. |
| Input Voltage Range | 2.7V–5.5V - matches USB 2.0/3.0 bus voltage tolerance and supports wide-input industrial rails. |
| Discharge Resistance | 105Ω typical - actively discharges output capacitance when disabled, preventing floating voltage on downstream loads. |
| Thermal Shutdown | +140°C threshold with +20°C hysteresis - cycles switch off/on until fault removal, protecting against prolonged overloads. |
Pinout & Package
AP2511AMP-13 is packaged in MSOP-8EP (exposed pad), a thermally enhanced 3mm × 3mm surface-mount package with 0.65mm pitch. The exposed pad must be soldered to PCB ground plane for optimal thermal performance (θJA = 92°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; connects to PCB ground plane and exposed pad. |
| IN (pins 2,3) | Power input | Accepts 2.7V–5.5V supply; requires 0.1µF ceramic bypass capacitor placed adjacent to pins. |
| EN (pin 4) | Enable control | Active-high logic input; asserts switch when pulled ≥2.0V; leakage <1µA when inactive. |
| FLG (pin 5) | Fault reporting | Open-drain output asserted low after 7ms deglitch upon overcurrent or overtemperature event. |
| OUT (pins 6,7) | Switched output | Delivers controlled power to load; all OUT pins must be externally tied together. |
| NC (pin 8) | No connection | Internally unconnected; recommended to tie to OUT for mechanical stability and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated output discharge | 105Ω internal discharge path ensures safe VOUT collapse when disabled - eliminates need for external bleed resistor. |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled (≤1µA reverse leakage at 5V), critical for multi-rail systems. |
| Built-in soft-start | 0.6ms typical rise time limits inrush current into heavy capacitive loads (e.g., 120µF USB ports), reducing input rail droop. |
| UVLO with hysteresis | 2.0V turn-on / 1.95V turn-off threshold prevents oscillation during brown-out conditions near USB minimum spec. |
| ESD robustness | 2kV HBM / 200V MM rating - withstands handling and board-level ESD events without latch-up or parameter shift. |
Applications
| USB 3.0 Hub Power Management | LCD Monitor Port Protection |
|---|---|
|
Use Scenario: Power delivery to four downstream USB 3.0 ports with individual overcurrent isolation. IC Role / Device Role / Timing Role: High-side switch per port, enforcing per-port 3.7A current limit and reporting faults via FLG to host controller. Use Value: Prevents single-port short from collapsing entire hub rail; 2µs response isolates fault before host detects enumeration failure. |
Use Scenario: Hot-swap power enable for HDMI/USB-C dual-function monitor input ports. IC Role / Device Role / Timing Role: Enables/disables 5V auxiliary power to interface ICs; discharge function clears residual voltage before reconfiguration. Use Value: Eliminates manual reset or power-cycle requirement when switching between HDMI and DP Alt Mode on same connector. |
| Docking Station Load Switching | Set-Top Box USB Peripheral Port |
|
Use Scenario: Controlled 5V power delivery to connected laptops, storage drives, and Ethernet adapters. IC Role / Device Role / Timing Role: High-side switch with thermal cycling protection during simultaneous high-current peripheral attach. Use Value: +140°C thermal shutdown with 20°C hysteresis sustains operation under 2.5A sustained load without permanent disable. |
Use Scenario: Isolated 5V power for USB-connected streaming sticks or wireless keyboards. IC Role / Device Role / Timing Role: Current-limited switch with UVLO ensuring clean power-up only after stable 5V rail establishment. Use Value: UVLO (2.0V) prevents erratic behavior during set-top box cold start when 5V rail ramps slowly. |
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 |
|---|---|---|---|
| AP2501AMP-13 | Active-low EN pin; identical RDS(ON), current limit, and protection features. | Requires inverted enable logic; suitable where system MCU GPIO is low-active or pull-down dominant. | Select when existing firmware or PCB layout uses active-low control signaling. |
| TCK112AG,LF | Lower 2.2A continuous rating; 110mΩ RDS(ON); no integrated discharge function. | Lacks output discharge - requires external 10kΩ resistor to GND for safe VOUT collapse. | Choose only if thermal budget allows higher conduction loss and board space permits external discharge component. |
Compared with AP2501AMP-13, the AP2511AMP-13 simplifies control logic integration in active-high systems; compared with TCK112AG,LF, it delivers lower conduction loss, faster fault response, and eliminates a discrete discharge resistor - reducing BOM count and improving reliability in USB-compliant designs.

FAQ
What is the maximum continuous output current supported by AP2511AMP-13?
The AP2511AMP-13 supports 2.5A continuous output current per Diodes' Recommended Operating Conditions. This rating assumes proper PCB thermal design (MSOP-8EP with exposed pad connected to ground plane) and ambient temperature ≤+85°C. At higher temperatures or reduced copper area, derating applies per θJA = 92°C/W and thermal shutdown threshold of +140°C.
Does AP2511AMP-13 require external components for fault reporting or discharge?
No external components are required for basic operation. The 7ms deglitch on the FLG pin eliminates false overcurrent reporting from capacitive inrush, and the integrated 105Ω discharge path safely collapses VOUT when disabled. Only a 0.1µF ceramic capacitor from IN to GND is mandatory; additional bulk capacitance is recommended for heavy loads.
How does the UVLO function behave during power ramp-up?
The UVLO turns the internal switch ON only when VIN rises above 2.0V (typical), with 50mV hysteresis. If VIN drops below 1.95V, the switch turns OFF within microseconds. This prevents partial turn-on and shoot-through during slow-ramping supplies, ensuring clean power sequencing in USB host controllers and embedded systems.
Can AP2511AMP-13 be used in dual-purpose ports like HDMI/MHL?
Caution is required: the integrated discharge function continuously drains connected batteries when disabled. In dual-purpose ports where output may be back-driven (e.g., MHL sink mode), this causes overstress on the discharge MOSFET. Diodes recommends avoiding AP2511AMP-13 in such configurations unless external isolation or discharge disable logic is implemented.
