Product details
Overview
AP2171AMP-13 from Diodes Incorporated is a single-channel, active-high enable, high-side USB power switch with 1.5A current limiting, 95mΩ on-resistance at 5V, and integrated short-circuit/thermal protection. It operates from 2.7V to 5.5V input, features 0.6ms typical rise time and 7ms deglitched open-drain fault flag (FLG), and is qualified for USB 2.0 hot-swap applications in laptops, docking stations, and set-top boxes.
For engineers reviewing the AP2171AMP-13 datasheet, AP2171AMP-13 pinout, AP2171AMP-13 application, or AP2171AMP-13 equivalent, this device delivers precise current limiting, reverse current blocking, and robust fault reporting without external components - critical for reliable USB port power management and hot-plug system design.
Technical Context
The AP2171AMP-13 integrates a low-RDS(ON) N-channel MOSFET with internal current-sense FET architecture, enabling accurate 1.5A over-current trip without external sensing resistors. Its UVLO threshold is 1.9V (typ), ensuring safe turn-on only after stable input rail establishment.
Thermal shutdown activates at ~140°C with 25°C hysteresis, and the FLG output asserts low after 7ms blanking to reject transient inrush events. The device supports dual-purpose ports by combining controlled voltage ramp-up with reverse current blocking during battery charging scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 1.5A typical; clamps sustained load current to prevent damage during overload or short circuit. |
| RDS(ON) | 95mΩ max at +25°C, VIN=5V; minimizes power loss and thermal rise under 1A continuous load. |
| Input Voltage Range | 2.7V–5.5V; compatible with USB 2.0 VBUS and wide-input industrial rails. |
| Rise Time | 0.6ms typical (CL=1µF, RL=10Ω); soft-starts downstream loads to suppress inrush current. |
| Shutdown Current | 1µA max; enables ultra-low-power state when disabled in battery-sensitive systems. |
| FLG Blanking Time | 7ms typical; eliminates false fault reporting from capacitive load transients without external RC. |
| UVLO Threshold | 1.9V typical; prevents erratic switching during brown-out or hot-insertion before stable supply. |
Pinout & Package
AP2171AMP-13 is supplied in MSOP-8EP (Exposed Pad) package, featuring thermal enhancement via soldered exposed pad connected to GND. Pin numbering follows standard MSOP-8EP top-view layout with pin 1 at bottom-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference and thermal sink | Primary return path; exposed pad must be soldered to PCB ground plane for θJA=60°C/W performance. |
| IN | Power input | Accepts 2.7V–5.5V supply; all IN pins (2 & 3) must be externally tied together. |
| EN | Enable control | Active-high logic input; drives internal gate driver to turn on high-side switch. |
| FLG | Fault reporting | Open-drain output pulled low during over-current or thermal fault after 7ms deglitch. |
| OUT | Switched power output | Delivers current-limited, UVLO-protected power to downstream load; pins 6 & 7 tied internally. |
Key Features
| Feature | Design Value |
|---|---|
| Reverse current blocking | Prevents backflow from OUT to IN when disabled, eliminating need for external blocking diode. |
| Integrated current-sense FET | Enables accurate 1.5A current limit without series sense resistor, preserving efficiency and board space. |
| Controlled rise/fall times | 0.6ms rise / 0.05ms fall ensures EMI-controlled turn-on and fast fault recovery without oscillation. |
| ESD robustness | 4kV HBM rating protects against handling damage in manufacturing and field service environments. |
| Green packaging | Halogen- and antimony-free, fully RoHS-compliant molding compound (<900ppm Br/Cl, <1000ppm Sb). |
Applications
| USB 2.0 Port Power Switching | Hot-Plug Module Protection |
|---|---|
|
Use Scenario: Single-port USB host or self-powered hub supplying 5V to peripherals. IC Role / Device Role / Timing Role: High-side power switch controlling VBUS delivery with over-current reporting to USB controller.

Use Scenario: Insertion of PCIe add-in cards or daughterboards into powered backplanes. IC Role / Device Role / Timing Role: Inrush current limiter and soft-start controller during live insertion. Use Value: 0.6ms rise time limits peak inrush to <1.5A, preventing main rail droop and connector arcing. |
| Dual-Purpose HDMI/MHL Charging Port | Laptop Docking Station Power Management |
|
Use Scenario: Shared mobile interface port delivering video (MHL) and simultaneous battery charging. IC Role / Device Role / Timing Role: Isolation switch enabling safe VBUS ramp before enabling charging circuitry. Use Value: UVLO ensures switch remains off until host VBUS stabilizes, preventing uncontrolled charge current surges. |
Use Scenario: Docking station supplying auxiliary 5V to USB peripherals, Ethernet PHYs, and display adapters. IC Role / Device Role / Timing Role: Independent channel power switch per downstream function with thermal fault isolation. Use Value: Thermal shutdown with 25°C hysteresis allows automatic recovery after transient overload, improving system uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IRHBR | Integrated USB 2.0 hub controller + power switches; includes built-in 1.5A current limit per port but requires full USB protocol stack. | Designed for multi-port hub ICs, not discrete single-channel switching; lacks standalone FLG reporting granularity. | Select when full USB enumeration and port control are required; not suitable as drop-in replacement for discrete switch use cases. |
| TPS2051BDBVR | 1.5A current limit, 110mΩ RDS(ON), active-high EN, but no UVLO and only 1ms FLG blanking (vs 7ms). | Less robust against capacitive inrush false triggers; requires external UVLO circuitry for hot-swap compliance. | Choose where cost is prioritized over fault immunity; verify system-level false-trip rate with large output capacitance. |
Compared with TUSB2036IRHBR and TPS2051BDBVR, the AP2171AMP-13 delivers superior inrush immunity via its 7ms deglitched FLG, native UVLO, and lower RDS(ON), making it optimal for standalone, high-reliability USB port protection without protocol overhead.

FAQ
What is the maximum continuous load current supported by AP2171AMP-13?
The AP2171AMP-13 is rated for 1.0A maximum continuous load current per the datasheet's Recommended Operating Conditions. Although its current limit is 1.5A, sustained operation above 1.0A risks exceeding thermal limits depending on PCB layout and ambient conditions - especially in the MSOP-8EP package with θJA=60°C/W.
Does AP2171AMP-13 require external components for basic over-current protection?
No. The device integrates current-sense FET, 7ms FLG deglitch timer, UVLO, and thermal shutdown - enabling full over-current and fault protection with zero external components. Only recommended bypass capacitors (0.01–0.1µF ceramic on IN/GND and OUT) are needed for stability and EMI control.
Can AP2171AMP-13 be used in battery-powered systems with strict quiescent current requirements?
Yes. With 1µA maximum shutdown current and 70µA typical enabled quiescent current, the AP2171AMP-13 meets stringent low-power demands. Its active-high EN allows direct connection to microcontroller GPIOs for dynamic power gating in portable devices.
How does the exposed pad on the MSOP-8EP package affect thermal performance?
The exposed pad must be soldered to a dedicated GND copper pour with ≥4 thermal vias to an inner ground plane. This configuration achieves θJA=60°C/W - reducing junction temperature rise by ~40°C versus non-thermal-pad layouts under 1A load, directly extending reliability and current capability.
