Product details
Overview
AP2501SN-7 from Diodes Incorporated is a single-channel, 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), and integrated output discharge. Designed for USB-compliant power delivery in compact consumer electronics, it operates across 2.7V–5.5V input and features active-low enable logic.
For engineers reviewing the AP2501SN-7 datasheet, AP2501SN-7 pinout, AP2501SN-7 application, or AP2501SN-7 equivalent, key selection criteria include its 2µs short-circuit response time, 7ms FLG deglitching, reverse current blocking, thermal shutdown at +140°C, and U-DFN2020-6 package suitability for space-constrained USB port protection.
Technical Context
The AP2501SN-7 integrates a P-channel MOSFET high-side switch with current-sense FET-based over-current detection and N-channel discharge transistor. Its UVLO (2.0V threshold) prevents turn-on until stable input is present, while built-in soft-start limits inrush via controlled 0.6ms rise time.
Thermal protection uses die-temperature sensing with +140°C shutdown and +20°C hysteresis, enabling automatic cycling under sustained overload. The open-drain FLG pin reports faults after 7ms blanking to suppress false triggers from capacitive load transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 2.5A - Maximum steady-state output current without thermal shutdown under recommended conditions. |
| Current Limit Threshold | 3.7A (typ) - Clamps output current during overload/short-circuit to prevent damage to downstream circuitry. |
| RDS(ON) | 70mΩ (typ @ 5V, 25°C) - Low conduction loss enabling efficient 2.5A switching in small U-DFN2020-6 package. |
| Short-Circuit Response Time | 2µs - Fast fault detection ensures minimal energy dissipation during hard shorts. |
| Input Voltage Range | 2.7V to 5.5V - Matches USB 2.0/3.0 bus voltage range and supports wide-input portable systems. |
| Enable Logic Polarity | Active Low - EN pin asserts switch ON when pulled low; compatible with standard microcontroller GPIO control. |
| FLG Blanking Time | 7ms (typ) - Prevents false fault reporting during output capacitor charging or transient inrush events. |
| Operating Temperature | −40°C to +85°C - Rated for industrial ambient environments in laptops, monitors, and set-top boxes. |
Pinout & Package
AP2501SN-7 is housed in a 6-pin U-DFN2020-6 package (2.0mm × 2.0mm, 0.5mm pitch), featuring wettable flanks and RoHS-compliant lead-free finish. Exposed pad is absent in this variant (unlike MSOP-8EP or U-DFN3030-8).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Voltage Input | Main power input; requires ≥0.1µF ceramic bypass capacitor to GND for stability and EMI suppression. |
| 2 - GND | Ground Reference | Primary return path for input, output, and internal circuitry; must be low-impedance connection. |
| 3 - EN | Enable Control | Active-low digital input; device enabled when pulled ≤0.8V, disabled when ≥2.0V. |
| 4 - FLG | Fault Reporting | Open-drain output asserted low during over-current or over-temperature; 7ms deglitch prevents chatter. |
| 5 - OUT | Switched Output | High-side switched output; connects to load; all OUT pins tied internally in multi-pin variants. |
| 6 - NC | No Connection | Internally unconnected; electrically isolated and recommended to tie externally to OUT for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | Active upon disable; provides 100Ω discharge path (typ) to safely bleed residual VOUT capacitance below 0.5V in <0.6ms. |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled; leakage <1µA at 5V reverse bias. |
| Built-in Soft-Start | Controls output rise time to 0.6ms (typ), eliminating inrush spikes into heavy capacitive loads (e.g., 120µF USB ports). |
| UVLO with Hysteresis | Turns on only above 2.0V (rising), turns off below 1.95V (falling); prevents oscillation near brown-out thresholds. |
| ESD Robustness | 2kV HBM / 200V MM rating enables handling in standard assembly environments without special precautions. |
Applications
| USB 2.0/3.0 Port Protection | LCD Monitor Power Sequencing |

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 |
|---|---|---|---|
| AP2511SN-7 | Same silicon, active-high EN pin instead of active-low; identical RDS(ON), current limit, and timing specs. | Requires inverted enable signal routing; suitable where host MCU GPIO defaults to high or pull-up architecture dominates. | Select when system-level enable logic is naturally high-active; no change needed to layout or thermal design. |
| TCK112G,LF | Lower 1.5A continuous rating, 120mΩ RDS(ON), no integrated discharge; requires external RC network for soft-start. | Lacks output discharge and shorter 1µs short-circuit response; not certified to UL/IEC60950-1. | Use only in cost-sensitive, low-current (<1.5A), non-safety-certified designs where board space allows external components. |
Compared with AP2511SN-7, the AP2501SN-7 offers identical protection and performance but simplifies interface to low-active control systems; versus TCK112G, it delivers higher current, lower loss, integrated discharge, and full safety certification-justifying its use in USB-compliant and thermally constrained designs.

FAQ
What is the maximum capacitive load the AP2501SN-7 can safely drive during turn-on?
The AP2501SN-7 is characterized for CL = 120µF with 0.6ms typical rise time and no thermal shutdown under 2.5A load. With proper 0.1µF IN bypass and PCB thermal vias, it reliably drives up to 470µF per the datasheet's inrush plots-provided input voltage remains ≥2.7V and ambient temperature stays ≤+70°C at full load.
Does the AP2501SN-7 require external components for basic operation?
No external components are required for core functionality: only a 0.1µF ceramic capacitor between IN and GND is mandatory for stability. The FLG deglitch, soft-start, discharge path, UVLO, and thermal shutdown are fully integrated-eliminating need for resistors, capacitors, or external FETs in standard USB port implementations.
How does the FLG pin behave during repeated short-circuit events?
When a short occurs, FLG goes low after 7ms blanking and stays low until both over-current and over-temperature conditions clear. If thermal shutdown cycles (e.g., due to sustained short), FLG remains asserted low throughout cycling and releases only after junction temperature falls below +120°C and load fault is removed.
Can the AP2501SN-7 be used in automotive infotainment USB ports?
No-the AP2501SN-7 is rated for −40°C to +85°C ambient and lacks AEC-Q100 qualification, extended temperature screening, or automotive-grade PPAP documentation. It is intended for commercial computing and consumer electronics-not automotive environments where 105°C operation and vibration tolerance are mandatory.
