Product details
Overview
AP2501AMP-13 from Diodes Incorporated is a single-channel, current-limited high-side power switch optimized for USB and hot-swap applications. It features 70 mΩ typical RDS(ON), 3.7 A typical current limit, 2 µs short-circuit response time, and integrated output discharge. It operates across 2.7 V to 5.5 V input voltage and delivers up to 2.5 A continuous load current in U-DFN3030-8 package with active-low enable.
For engineers reviewing the AP2501AMP-13 datasheet, AP2501AMP-13 pinout, AP2501AMP-13 application, or AP2501AMP-13 equivalent, key selection criteria include its fast fault response, reverse current blocking, UVLO (2.0 V threshold), thermal shutdown at +140°C, and compatibility with heavy capacitive loads in USB-powered peripherals.
Technical Context
The AP2501AMP-13 integrates a P-channel MOSFET high-side switch with current-sense FET-based overload detection and an N-channel discharge transistor. Its 7 ms deglitch on the open-drain FLG pin prevents false fault reporting during inrush or transient overloads.
It implements under-voltage lockout (UVLO) with 50 mV hysteresis, thermal shutdown with +20°C hysteresis, and soft-start via controlled rise time (0.6 ms typical). The device supports dual-rail operation with independent IN/OUT pins and requires no external components for basic protection functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 70 mΩ typ @ 5 V IN, 1 A - enables low conduction loss and minimal self-heating at rated load |
| Current Limit | 3.7 A typ - clamps output current during overload without latch-off, sustaining safe operation |
| Short-Circuit Response | 2 µs - detects and limits fault current before system-level damage occurs |
| Input Voltage Range | 2.7 V to 5.5 V - matches USB 2.0/3.0 bus and portable system supply rails |
| UVLO Threshold | 2.0 V rising - prevents erratic switching during brown-out or hot-plug ramp-up |
| Thermal Shutdown | +140°C with +20°C hysteresis - autonomously cycles off/on to survive sustained short circuits |
| Output Discharge | Active when disabled - discharges output capacitance via internal 105 Ω path, eliminating floating voltage |
Pinout & Package
AP2501AMP-13 is packaged in U-DFN3030-8 (Type E), a 3.0 mm × 3.0 mm, 0.5 mm pitch, thermally enhanced surface-mount package with exposed pad for GND connection and improved thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 2,3) | Power Input | High-side switch source node; must be decoupled with ≥0.1 µF ceramic capacitor to GND |
| EN (Pin 4) | Enable Control | Active-low logic input; asserts switch when pulled low; compatible with 1.8 V/3.3 V/5 V logic |
| FLG (Pin 5) | Fault Reporting | Open-drain output asserted low after 7 ms deglitch upon overcurrent or overtemperature |
| OUT (Pins 6,7) | Power Output | Switched output node; all OUT pins tied together externally; drives downstream load |
| GND (Pin 1) | Ground Reference | Primary return path for power and logic; connects to exposed pad for thermal management |
| NC (Pin 8) | No Connect | Internally unconnected; recommended to tie externally to OUT for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 105 Ω internal discharge path ensures rapid, controlled VOUT collapse when disabled |
| Reverse Current Blocking | Prevents backflow from VOUT to VIN when disabled - critical for multi-rail USB systems |
| 7 ms Fault Blanking | Eliminates false FLG assertions during inrush or capacitive transients - no external RC needed |
| Built-in Soft-Start | 0.6 ms typical output rise time limits inrush current into large downstream capacitance |
| Robust ESD Protection | 2 kV HBM / 200 V MM - meets IEC61000-4-2 level 4 requirements for board-level reliability |
Applications
| USB Hub Power Management | Laptop Docking Station Ports |
|---|---|
|
Use Scenario: Individual port power control in multi-port USB 3.0 hubs with 120 µF output capacitance. IC Role / Device Role / Timing Role: High-side switch enabling/disabling VBUS per port; provides current limiting and fault isolation. Use Value: Prevents bus-wide shutdown during single-port short circuit; FLG signal triggers host firmware recovery. |
Use Scenario: Hot-swap power delivery to peripheral devices (e.g., monitors, storage) via laptop docking station. IC Role / Device Role / Timing Role: Load switch with reverse current blocking and fast (<2 µs) fault response during plug/unplug events. Use Value: Eliminates voltage droop and backfeed risks when peripherals are connected/disconnected live. |
| Set-Top Box USB Peripherals | Industrial USB Host Interfaces |
|
Use Scenario: Powering external HDDs or Wi-Fi adapters from residential gateways with strict thermal constraints. IC Role / Device Role / Timing Role: Current-limited power switch with thermal cycling behavior (+140°C trip, +120°C recovery). Use Value: Sustains operation under intermittent overload without permanent shutdown - improves field reliability. |
Use Scenario: Isolating USB ports in industrial HMIs where ESD exposure and long-term uptime are critical. IC Role / Device Role / Timing Role: Robust power switch with 2 kV HBM ESD rating and green RoHS-compliant packaging. Use Value: Reduces field failures due to electrostatic discharge in factory-floor environments. |
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 |
|---|---|---|---|
| TPS22965DRLR | Lower RDS(ON) (42 mΩ), but no integrated discharge; requires external pull-down for FLG | Lacks built-in output discharge - unsuitable where rapid VOUT collapse is required | Choose when lowest conduction loss is prioritized and discharge is handled externally |
| RT9711CGJ5 | Higher current limit (5 A), but slower response (10 µs) and no UVLO hysteresis | Less robust against input brown-out during hot-swap; higher thermal impedance in same footprint | Choose only if higher trip current outweighs need for fast fault reaction and stable UVLO |
Compared with TPS22965DRLR and RT9711CGJ5, AP2501AMP-13 uniquely combines fast 2 µs fault response, integrated discharge, and 50 mV UVLO hysteresis - making it optimal for USB-compliant hot-swap systems requiring autonomous, component-level protection without external support circuitry.

FAQ
What is the function of the NC pin on AP2501AMP-13?
The NC (No Connect) pin (Pin 8) has no internal connection and serves no electrical function. Diodes Incorporated recommends tying it externally to the OUT net to improve noise immunity and reduce parasitic antenna effects in high-frequency layouts. It must not be left floating in production designs.
Does AP2501AMP-13 support reverse voltage protection?
Yes - AP2501AMP-13 provides reverse current blocking: when disabled and VOUT > VIN, the internal P-MOSFET body diode is reverse-biased and leakage remains below 1 µA (typical at 5 V). This prevents backfeed from downstream capacitors or powered peripherals into the input rail.
How does the FLG pin behave during thermal shutdown?
During thermal shutdown, the FLG pin goes low after the 7 ms deglitch timeout and remains low until both overtemperature and overcurrent conditions are fully cleared. It does not pulse or toggle - it stays asserted until junction temperature falls below the hysteresis threshold (~120°C) and load fault is removed.
Can AP2501AMP-13 drive a 120 µF output capacitor safely?
Yes - the device's built-in soft-start (0.6 ms typical rise time) and 3.7 A current limit ensure controlled inrush into 120 µF loads. Application Note DS37745 confirms stable operation with 120 µF/2.5 Ω loads and shows full recovery from short-circuit events without latch-up or damage.
