Product details
Overview
AP2511S-13 from Diodes Incorporated is a single-channel, current-limited high-side power switch optimized for USB and hot-swap applications. It features active-high enable, 3.7A typical 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 and delivers up to 2.5A continuous load current in SO-8 package.
For engineers reviewing the AP2511S-13 datasheet, AP2511S-13 pinout, AP2511S-13 application, or AP2511S-13 equivalent, key selection criteria include enable polarity compatibility, thermal shutdown threshold (+140°C), FLG deglitch timing (7ms), reverse current blocking capability, and SO-8 package thermal resistance (96°C/W).
Technical Context
The AP2511S-13 integrates a P-channel MOSFET high-side switch with current-sense FET-based over-current detection and N-channel discharge transistor. Its UVLO activates at 2.0V (rising) with 50mV hysteresis, ensuring reliable turn-on only after stable rail establishment.
Thermal protection uses die-temperature sensing with +140°C trip threshold and +20°C hysteresis, enabling auto-recovery cycling during sustained overload. The open-drain FLG output reports both over-current and over-temperature faults with built-in 7ms blanking to suppress false triggers from capacitive inrush.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 3.7A typical - clamps output current to prevent damage during short circuit or overload. |
| RDS(ON) | 70mΩ typical at VIN = 5V, TA = +25°C - minimizes conduction loss and self-heating under 2.5A load. |
| Short-Circuit Response | 2µs - enables rapid current limiting before energy dissipation exceeds safe limits. |
| Enable Polarity | Active High - simplifies interface with microcontroller GPIOs without level-shifting or inversion logic. |
| Output Discharge | Integrated resistive path (RDIS ≈ 100Ω) - safely drains output capacitance when disabled, preventing floating voltage. |
| FLG Blanking Time | 7ms typical - eliminates false fault reporting during startup or heavy capacitive load switching. |
| UVLO Threshold | 2.0V rising, 1.95V falling - prevents erratic switching during brown-out or hot-plug ramp-up. |
Pinout & Package
AP2511S-13 is supplied in SO-8 package with exposed pad (non-electrical ground path, must be thermally connected to PCB ground plane). Pin 1 = GND, Pin 2/3 = IN (tied externally), Pin 4 = EN (active high), Pin 5 = FLG (open-drain), Pin 6/7 = OUT (tied externally), Pin 8 = NC (recommended tied to OUT).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Power and signal reference ground | Reference node for all internal circuits; requires low-impedance connection to PCB ground plane. |
| IN (Pins 2 & 3) | Input voltage supply | Dual pins for lower inductance; must be tied together externally and bypassed with ≥0.1µF ceramic capacitor near device. |
| EN (Pin 4) | Enable control input | Active-high logic input; drives internal driver stage; compatible with 3.3V/5V CMOS logic levels. |
| FLG (Pin 5) | Fault reporting output | Open-drain output pulled low during over-current or over-temperature; includes 7ms deglitch to reject transient spikes. |
| OUT (Pins 6 & 7) | Switched output voltage | Dual pins reduce trace resistance/inductance; must be tied together externally and routed to load with minimal loop area. |
| NC (Pin 8) | No internal connection | Not bonded; recommended tied to OUT to minimize EMI and improve thermal coupling of adjacent pins. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 100Ω discharge path ensures controlled VOUT decay to <0.5V within 0.6ms when disabled - avoids residual voltage hazards in USB hot-swap. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled - essential for multi-rail systems and battery-backed loads. |
| Built-in Soft-Start | 0.6ms typical rise time limits inrush current into large output capacitors - reduces stress on upstream regulators and connectors. |
| Thermal Shutdown Recovery | +140°C trip with +20°C hysteresis enables automatic cycling during sustained overload - maintains system visibility without latch-off. |
| ESD Robustness | 2kV HBM / 200V MM - meets industrial handling requirements without external protection diodes. |
Applications
| USB Host Port Protection | LCD Monitor Power Sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2501S-13 | Active-low enable; otherwise identical electrical specs, pinout, and SO-8 package. | Requires inverted control signal - unsuitable where MCU GPIO is directly connected without logic inversion. | Select when system-level enable logic is active-low or when consolidating BOM with AP2501-based designs. |
| TCK107AG,LF | Lower 2.2A current limit; 110mΩ RDS(ON); no integrated discharge; different pinout (SOT-23-6). | Limited to lighter loads; lacks output discharge - requires external circuitry for VOUT bleed-down. | Choose only for space-constrained, low-power applications where discharge function is unnecessary and thermal budget allows higher RDS(ON). |
Compared with AP2501S-13, AP2511S-13 offers direct GPIO compatibility without inversion; compared with TCK107AG,LF, it provides higher current capacity, lower conduction loss, and integrated discharge-making it superior for USB-compliant, thermally demanding hot-swap roles.

FAQ
What is the maximum continuous load current supported by AP2511S-13?
The AP2511S-13 supports 2.5A maximum continuous load current under recommended operating conditions (TA ≤ +85°C, VIN = 2.7V–5.5V). At 5V input and +25°C ambient, its 70mΩ RDS(ON) yields ~0.44W conduction loss at 2.5A, well within SO-8 thermal limits when properly heatsinked.
Does AP2511S-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; optional 120µF+ output capacitance improves surge immunity. The FLG deglitch, discharge path, UVLO, and thermal shutdown are fully internal - no resistors, capacitors, or diodes needed.
How does the FLG pin behave during a short-circuit event?
When a short occurs, the AP2511S-13 enters current-limit mode within 2µs. After a 7ms deglitch window, FLG pulls low if the fault persists. FLG remains low until both over-current and over-temperature conditions clear. It releases high-Z upon recovery, requiring an external pull-up resistor (typically 10kΩ) to MCU interrupt pin.
Can AP2511S-13 be used in dual-purpose ports like MHL or USB-C with power delivery?
No - Diodes' datasheet explicitly advises against use in dual-purpose ports (e.g., HDMI/MHL) where output voltage may be back-driven while the switch is disabled. The integrated discharge function would continuously drain peripheral batteries, and sustained reverse bias risks overstressing the discharge MOSFET.
