Product details
Overview
AP2162AFGEG-7 from Diodes Incorporated is a dual-channel, active-low enable, 1.4A current-limiting high-side power switch with integrated output discharge, designed for USB 2.0 hot-swap and capacitive-load applications. It delivers 85mΩ on-resistance at 5V, 2µs short-circuit response, and operates across 2.7V–5.5V input range with -40°C to +85°C ambient rating.
For engineers reviewing the AP2162AFGEG-7 datasheet, AP2162AFGEG-7 pinout, AP2162AFGEG-7 application, or AP2162AFGEG-7 equivalent, key selection criteria include dual-channel independent enable control, 7ms deglitched fault flag timing, reverse current blocking, thermal shutdown at +140°C, and U-DFN3030-8 (Type E) package compatibility with exposed pad thermal management.
Technical Context
The AP2162AFGEG-7 implements two independent pMOS high-side switches with per-channel current sensing, UVLO (2.0V threshold), and thermally coupled shutdown at +140°C with +25°C hysteresis. Each channel features dedicated open-drain FLG outputs with 7ms blanking to suppress false overcurrent reporting during capacitive inrush.
Its discharge function activates automatically upon disable or power-down, providing a 100Ω resistive path to safely dissipate output capacitance energy. The device uses sense-FET current limiting-no external resistor-enabling accurate 1.4A trip threshold without added series resistance in the power path.
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 events |
| On-Resistance (RDS(ON)) | 85mΩ max at 5V/25°C - minimizes conduction loss and self-heating under 1A load |
| Short-Circuit Response | 2µs - enables rapid current limiting before destructive energy accumulates |
| Input Voltage Range | 2.7V to 5.5V - supports full USB 2.0 bus voltage tolerance and legacy 3.3V/5V systems |
| Enable Polarity | Active Low - EN1/EN2 assert low to turn on respective channel, simplifying direct MCU GPIO control |
| Output Discharge Resistance | 100Ω typical - provides controlled discharge of up to 10µF output capacitance when disabled |
| FLG Blanking Time | 7ms typ - filters transient inrush spikes, eliminating need for external RC filtering on fault reporting |
| Thermal Shutdown Threshold | +140°C with +25°C hysteresis - ensures safe cycling during sustained overload without latch-off |
Pinout & Package
AP2162AFGEG-7 is packaged in U-DFN3030-8 (Type E) with exposed thermal pad - requires solder connection to PCB ground plane for optimal thermal performance (θJA = 60°C/W). Pin 1 is FLG1; pin numbering follows standard top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FLG1 (Pin 1) | Open-drain fault flag, Channel 1 | Active-low signal indicating overcurrent or overtemperature on OUT1; 7ms deglitch prevents false triggers |
| OUT1 (Pin 7) | Channel 1 power output | Switched 2.7–5.5V output with reverse current blocking and 100Ω discharge path when disabled |
| FLG2 (Pin 5) | Open-drain fault flag, Channel 2 | Independent fault reporting for OUT2; electrically isolated from FLG1 for concurrent monitoring |
| OUT2 (Pin 6) | Channel 2 power output | Dual independent switching node; supports ganged operation with combined 2.8A limit when tied |
| GND (Pin 1 EP) | Ground reference & thermal pad | Exposed pad must be soldered to solid GND copper area - not used as primary current return path |
| IN (Pin 3) | Main power input | Accepts 2.7–5.5V supply; feeds both channels; bypass capacitor required within 2mm |
| EN1 (Pin 4) | Channel 1 enable input | Active-low logic interface - pulled high internally; compatible with 1.8V/3.3V/5V GPIO |
| EN2 (Pin 2) | Channel 2 enable input | Independent active-low control; allows staggered power-up sequencing between loads |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent current-limited channels | Each channel limits to 1.4A typ with separate EN/FLG - enables selective load powering and fault isolation |
| Integrated output discharge | 100Ω internal discharge path activated on disable - eliminates need for external bleed resistors on USB ports |
| 7ms deglitched fault reporting | Hardware-based blanking on FLG pins - rejects <7ms transients from capacitor charging, no external components needed |
| Reverse current blocking | Prevents backflow from loaded OUTx to IN during power loss or hot-removal - critical for USB compliance |
| Thermally robust U-DFN3030-8 | 60°C/W junction-to-ambient thermal resistance - sustains 1A continuous per channel at +85°C ambient |
| USB-compliant hot-swap control | Meets USB 2.0 inrush and short-circuit requirements with controlled 0.6ms rise time and UVLO at 2.0V |
Applications
| USB 2.0 Hub Power Management | Laptop Docking Station Ports |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2172AFGEG-7 | Active-high enable inputs instead of active-low; identical current limit, RDS(ON), and package | Requires inverted logic drive or pull-down configuration; preferred where MCU GPIO defaults high | Select when system-level enable logic is active-high or when synchronizing with other active-high peripherals |
| TCK112G,LF | Single-channel 1.5A switch with 100mΩ RDS(ON); no integrated discharge; 1.8–6V input range | Lacks dual-channel independence and output discharge - requires external circuitry for USB compliance | Use only for single-load applications where discharge and dual fault reporting are not required |
Compared with AP2162AFGEG-7, AP2172AFGEG-7 offers identical protection and performance but shifts enable polarity, while TCK112G,LF trades integration for wider input range and higher RDS(ON), increasing conduction loss and requiring external discharge components.

FAQ
What is the maximum continuous load current per channel for AP2162AFGEG-7?
The AP2162AFGEG-7 supports 1.0A maximum continuous load current per channel under recommended operating conditions (2.7V–5.5V input, -40°C to +85°C ambient). Its 1.4A current limit is a fault-trip threshold-not a steady-state rating-and thermal derating applies above +60°C ambient due to its 60°C/W θJA.
Does AP2162AFGEG-7 require external components for USB 2.0 compliance?
No external components are required for core USB 2.0 hot-swap compliance. The device integrates 7ms FLG deglitching, 100Ω output discharge, reverse current blocking, and 0.6ms soft-start. Only a 0.1–1µF ceramic bypass capacitor on IN-GND (within 2mm) and optional 10µF output bulk capacitor are recommended per the datasheet.
How does the output discharge function operate in AP2162AFGEG-7?
The discharge function activates automatically when EN1 or EN2 is deasserted (high), or during power-up/power-down when VIN falls below UVLO (≈2.0V). It connects a 100Ω internal nMOS path from OUTx to GND, safely dissipating stored charge in external capacitors-eliminating need for external bleed resistors on USB VBUS lines.
Can AP2162AFGEG-7 be used in automotive applications?
AP2162AFGEG-7 is not AEC-Q100 qualified and is specified for industrial temperature range (-40°C to +85°C), not automotive grade. Diodes Incorporated explicitly states that automotive use requires contacting their representatives for PPAP-capable, IATF 16949-manufactured variants-this part is intended for commercial computing and consumer electronics.
