Product details
Overview
AP2172AMPG-13 from Diodes Incorporated is a dual-channel, 1.4A current-limiting high-side power switch with integrated output discharge, designed for USB and hot-swap applications. It features active-high enable inputs, 85mΩ typical RDS(ON), 2µs short-circuit response time, and built-in undervoltage lockout (2.0V threshold), operating across 2.7V–5.5V input range in U-DFN3030-8 (Type E) package.
For engineers reviewing the AP2172AMPG-13 datasheet, AP2172AMPG-13 pinout, AP2172AMPG-13 application, or AP2172AMPG-13 equivalent, key selection criteria include per-channel current limiting accuracy, thermal shutdown behavior (+140°C trip), FLG deglitch timing (7ms typ), and compatibility with heavy capacitive loads in USB 2.0 hub and docking station designs.
Technical Context
The AP2172AMPG-13 implements two independent pMOS high-side switches with dedicated current-sense FETs and thermal sensing per channel. Each channel delivers controlled turn-on (0.6ms typical rise time) and fast fault detection (2µs short-circuit response), with open-drain FLG outputs asserting low after 7ms deglitch upon overcurrent or overtemperature events.
Its discharge function activates automatically when disabled, providing a 100Ω resistive path to ground for output capacitors - eliminating need for external discharge circuitry. UVLO (2.0V typ) ensures switch remains off until stable input is established, critical for hot-plug reliability in host-powered USB systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (Typ) | 1.4A per channel - clamps output current to prevent damage during overload or short-circuit conditions. |
| RDS(ON) (Typ) | 85mΩ at VIN = 5V, TA = +25°C - minimizes conduction loss and self-heating under 1A continuous load. |
| Short-Circuit Response | 2µs - enables rapid current limiting before destructive energy accumulates in downstream capacitance. |
| FLG Blanking Time | 7ms typical - suppresses false fault reporting during inrush transients from large output capacitors. |
| Discharge Resistance | 100Ω - provides controlled, predictable discharge of output storage capacitors when disabled. |
| UVLO Threshold | 2.0V typical - prevents erratic switching during brown-out or power-up sequencing in USB-compliant systems. |
| Thermal Shutdown | +140°C junction temperature - protects device during sustained overload; +25°C hysteresis enables automatic recovery. |
Pinout & Package
AP2172AMPG-13 is packaged in U-DFN3030-8 (Type E) - a thermally enhanced 3.0mm × 3.0mm × 0.55mm exposed-pad package requiring GND connection to the pad for optimal thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Primary supply rail (2.7V–5.5V); connects to upstream source before distribution to dual channels. |
| EN1 / EN2 | Active-High Enable Inputs | Independent logic-level controls for each channel; high = enabled, low = disabled + discharge activation. |
| OUT1 / OUT2 | Switched Power Outputs | High-side switched outputs delivering regulated current-limited power to downstream loads (e.g., USB ports). |
| FLG1 / FLG2 | Open-Drain Fault Flags | Active-low indicators signaling overcurrent or overtemperature on respective channel; 7ms deglitch built-in. |
| GND | Ground Reference | Common return path for power, logic, and thermal management; must be connected to exposed pad. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-channel current limiting | Independent 1.4A per channel with ganged limit up to 2.8A - supports redundant or parallel load paths without external coordination. |
| Integrated output discharge | 100Ω internal discharge path activated on disable - eliminates need for external MOSFET + resistor network in USB port designs. |
| Controlled soft-start | 0.6ms typical output rise time - limits inrush current into 10µF+ capacitive loads, meeting USB 2.0 hub requirements. |
| Robust fault reporting | 7ms deglitched FLG outputs - rejects transient spikes from plug-in events while reliably signaling sustained faults. |
| Reverse current blocking | Prevents backflow from OUT to IN when disabled - essential for preventing power coupling between isolated USB downstream ports. |
Applications
| USB 2.0 Hub Power Management | Laptop Docking Station Ports |
|---|---|
Use Scenario: Distributing 5V power to four downstream USB 2.0 ports with individual overcurrent protection and hot-plug capability. IC Role / Device Role / Timing Role: Dual high-side switch controlling power delivery per port pair; enables/disables ports independently with <0.6ms rise time. Use Value: Meets USB-IF specification for port power sequencing and fault isolation; eliminates need for discrete current-sense resistors and external discharge FETs. |
Use Scenario: Providing protected 5V power to HDMI, USB-C, and Ethernet interfaces on a laptop docking station with shared upstream bus. IC Role / Device Role / Timing Role: Dual-channel load switch managing separate power domains; UVLO ensures clean power-up/down sequencing during attach/detach. Use Value: Prevents system reset or voltage droop during hot insertion; thermal shutdown (+140°C) avoids latch-up under sustained 1A-per-port load. |
| Set-Top Box Peripheral Ports | Industrial USB Host Interface |
Use Scenario: Powering USB peripherals (keyboard, storage) on residential gateways with strict EMI and surge immunity requirements. IC Role / Device Role / Timing Role: High-side switch enforcing current limit and short-circuit protection per peripheral port; FLG signals faults to MCU for logging. Use Value: 2µs fault response and 7ms deglitch ensure reliable operation despite noisy 12V-to-5V DC/DC ripple and cable-induced transients. |
Use Scenario: Isolating USB host controller power in industrial HMIs where ESD robustness and long-term thermal stability are critical. IC Role / Device Role / Timing Role: Dual-channel protected power switch enabling/disabling USB VBUS with reverse-current blocking and -40°C to +85°C operation. Use Value: 2kV HBM ESD rating and halogen-free "Green" packaging meet IEC 61000-4-2 and RoHS 3 compliance for factory-floor deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL9202DRVR | Single-channel, 2.5A limit, no integrated discharge, 120mΩ RDS(ON) | Lacks dual-channel independence and output discharge - requires external circuitry for USB port discharge. | Use only if higher current per channel is required and board space allows added discharge components. |
| TPS2051BDR | Single-channel, 1.5A limit, no FLG deglitch, 130mΩ RDS(ON), no UVLO | No built-in 7ms blanking or 2.0V UVLO - prone to false fault reporting in noisy environments. | Suitable for non-USB legacy systems where cost is prioritized over robust hot-swap behavior. |
Compared with TPL9202DRVR and TPS2051BDR, the AP2172AMPG-13 delivers true dual-channel autonomy, integrated discharge, and deterministic 7ms fault reporting - reducing BOM count and improving USB compliance margin without sacrificing thermal safety or ESD resilience.

FAQ
What is the maximum continuous load current per channel for AP2172AMPG-13?
The AP2172AMPG-13 supports 1.0A maximum continuous load current per channel under recommended operating conditions (TA ≤ +85°C, VIN = 2.7V–5.5V). Its 1.4A typical current limit provides headroom for short-duration inrush, but sustained operation above 1.0A risks thermal shutdown due to power dissipation in the 85mΩ RDS(ON).
Does AP2172AMPG-13 require external components for output discharge?
No. The AP2172AMPG-13 integrates a 100Ω discharge path activated automatically when EN1 or EN2 is deasserted. This eliminates the need for external MOSFETs, resistors, or control logic - simplifying layout and ensuring consistent discharge behavior across temperature and voltage ranges.
How does the 7ms FLG deglitch function impact system fault handling?
The 7ms deglitch on FLG1/FLG2 prevents false overcurrent assertions caused by capacitive inrush during hot-plug events. Only faults persisting beyond this window trigger a low-level flag, allowing microcontrollers to distinguish transient surges from genuine shorts - reducing unnecessary port resets and improving system uptime.
Can AP2172AMPG-13 operate with a 3.3V input supply?
Yes. The AP2172AMPG-13 operates across 2.7V–5.5V input range. At 3.3V, its RDS(ON) increases to 105mΩ (typ) and current limit remains 1.4A (typ), making it suitable for 3.3V USB OTG or low-voltage industrial bus applications - though thermal margin decreases slightly versus 5V operation.
