Product details
Overview
AP2171DMPG-13 from Diodes Incorporated is a single-channel, active-high enable, high-side USB power switch with integrated output discharge, 1.5A current limiting, 90mΩ RDS(ON) (U-DFN2018-6), and 7ms deglitched fault reporting - designed for hot-swap USB 2.0 ports in laptops, docking stations, and USB HUBs.
For engineers reviewing the AP2171DMPG-13 datasheet, AP2171DMPG-13 pinout, AP2171DMPG-13 application, or AP2171DMPG-13 equivalent, this device delivers precise over-current protection, reverse current blocking, UVLO, thermal shutdown with 25°C hysteresis, and controlled 0.6ms rise time - critical for reliable USB port power sequencing and fault resilience.
Technical Context
The AP2171D implements a thermally protected, slew-rate-controlled N-channel MOSFET high-side switch with internal current-sense FET and deglitched open-drain FLG output. Its UVLO activates at 1.9V (rising) and deactivates at ~1.6V (falling), ensuring safe startup and removal in hot-plug systems.
Discharge functionality engages automatically on EN de-assertion via an internal 100Ω NMOS path, enabling rapid VOUT collapse (<0.6ms for 1µF). The 7ms FLG blanking window suppresses false over-current triggers during capacitive load turn-on transients without external RC networks.
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) | 90mΩ max (U-DFN2018-6, VIN=5V, TA=25°C); minimizes conduction loss and self-heating at 1A. |
| Input Voltage Range | 2.7V–5.5V; supports full USB 2.0 bus voltage range including low-voltage battery-backed operation. |
| Rise Time | 0.6ms typical (CL=1µF, RLOAD=10Ω); provides soft-start to limit inrush current during hot-plug events. |
| Shutdown Current | 1µA max; enables ultra-low power state when disabled - critical for battery-powered USB peripherals. |
| FLG Blanking Time | 7ms typical; eliminates false fault reporting during transient over-currents (e.g., capacitor charging). |
| Discharge Resistance | 100Ω nominal; ensures rapid, controlled VOUT decay to <0.5V within 0.6ms (CL=1µF). |
Pinout & Package
AP2171DMPG-13 is packaged in U-DFN2018-6: 2.0mm × 1.8mm, 0.5mm pitch, exposed thermal pad (to be connected to GND for optimal θJA = 70°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and thermal conduction path via exposed pad. |
| 2 | IN | Main input voltage supply (2.7V–5.5V); connects to upstream USB VBUS or system rail. |
| 3 | EN | Active-high enable control; logic high ≥2V enables switch, logic low ≤0.8V disables it. |
| 4 | FLG | Open-drain fault flag; pulled low during over-current or over-temperature events (7ms deglitch applied). |
| 5, 6 | OUT | Switched output; tied together internally; supplies downstream USB load with discharge path when disabled. |
Key Features
| Feature | Design Value |
|---|---|
| Output Discharge | Integrated 100Ω NMOS discharge path activated on EN de-assertion - eliminates need for external bleed resistors. |
| Reverse Current Blocking | Prevents backflow from OUT to IN when VOUT > VIN and switch is off - protects upstream power sources. |
| UVLO with Hysteresis | Enables only above 1.9V (rising), disables below ~1.6V (falling) - prevents erratic switching near brown-out thresholds. |
| Thermal Protection | Shuts down at ~140°C junction temperature; auto-recovers after cooling by ~25°C - avoids permanent latch-up. |
| ESD Robustness | 4kV HBM / 300V MM - meets industrial handling requirements without additional protection circuitry. |
Applications
| USB 2.0 Port Power Switching | Laptop Docking Station Power Management |
|---|---|
|

IC Role / Device Role / Timing Role: Load switch with discharge and thermal protection for modular expansion interfaces. Use Value: Enables safe hot-insertion/removal of modules while maintaining system stability and preventing back-powering. |
| Desktop PC Front-Panel USB Hub | USB-C Alternate Mode Power Switching |
|
Use Scenario: Providing isolated, protected VBUS to front-panel USB ports on desktop motherboards. IC Role / Device Role / Timing Role: Single-channel current-limited power switch with UVLO and reverse-blocking. Use Value: Eliminates need for discrete MOSFET + gate driver + protection IC; reduces BOM count and layout area. |
Use Scenario: Switching VBUS in USB-C receptacles supporting Alternate Mode (e.g., DisplayPort over USB-C). IC Role / Device Role / Timing Role: High-side switch with fast fault response and output discharge for mode negotiation safety. Use Value: Ensures clean power ramp and rapid discharge between mode transitions - avoids signal integrity issues during reconfiguration. |
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 |
|---|---|---|---|
| TCK107AG,314 (Toshiba) | 1.2A current limit, 120mΩ RDS(ON), no integrated discharge, active-high EN. | Lacks output discharge function - requires external resistor network for VOUT collapse. | Choose when lower cost and simpler fault reporting suffice, and discharge is handled externally. |
| TPS22965DSGT (TI) | 2A current limit, 42mΩ RDS(ON), 0.5ms rise time, no UVLO, active-high EN. | No undervoltage lockout - risks erratic behavior during brown-out; higher RDS(ON) not applicable here (lower value). | Choose for higher current/low-RDS(ON) needs where UVLO is managed upstream or unnecessary. |
Compared with TCK107AG,314 and TPS22965DSGT, AP2171DMPG-13 uniquely integrates UVLO, 7ms deglitched FLG, and 100Ω discharge in a 2.0×1.8mm package - delivering complete USB 2.0 hot-swap functionality without external components.

FAQ
What is the maximum continuous load current supported by AP2171DMPG-13?
The AP2171DMPG-13 supports 1A maximum continuous load current per its recommended operating conditions, despite a 1.5A typical current limit. This rating accounts for thermal derating across -40°C to +85°C ambient and ensures reliable operation without exceeding junction temperature limits in standard PCB layouts.
Does AP2171DMPG-13 require external components for basic USB port protection?
No external components are required for core functionality: UVLO, over-current protection, thermal shutdown, and output discharge are fully integrated. Only recommended external elements are 0.1µF ceramic bypass (IN–GND), 10µF+ bulk capacitor (OUT), and optional pull-up on FLG - no sense resistors, RC timers, or discharge resistors needed.
How does the 7ms FLG deglitch timing affect system fault detection?
The 7ms deglitch window filters out brief current spikes (e.g., during capacitor charging or ESD events), preventing false FLG assertions. Fault reporting occurs only if over-current or over-temperature persists beyond 7ms - ensuring firmware receives actionable, stable fault signals rather than transient noise.
Can AP2171DMPG-13 be used in USB-C applications?
Yes - AP2171DMPG-13 is suitable for USB-C VBUS switching in non-PD (Power Delivery) implementations, such as USB-C Alternate Mode (e.g., DisplayPort) where fixed 5V power is required. It is not rated for USB PD's variable voltage or 3A+ currents, but excels in 5V/1A USB-C peripheral power switching with discharge and protection.
