Product details
Overview
AP2182AMPG-13 from Diodes Incorporated is a dual-channel, active-low enable, current-limited high-side power switch optimized for USB 2.0 and hot-swap applications. It delivers 1.5A continuous per channel, features 85mΩ typical RDS(ON) at 5V input, 2µs short-circuit response time, integrated output discharge, and operates across 2.7V–5.5V input range. It protects systems with reverse-current blocking, overcurrent, overtemperature, UVLO, and 7ms deglitched fault reporting - deployed in laptop USB hubs and set-top box power rails.
For engineers reviewing the AP2182AMPG-13 datasheet, AP2182AMPG-13 pinout, AP2182AMPG-13 application, or AP2182AMPG-13 equivalent, key selection criteria include active-low enable polarity, dual-channel independent control, 2.0A current-limit accuracy, SO-8/MSOP-8EP/DFN3030E-8 package compatibility, and integrated discharge functionality for capacitive load management.
Technical Context
The AP2182A implements two independent P-channel MOSFET high-side switches with dedicated EN1/EN2 inputs (active-low) and open-drain FLG1/FLG2 outputs. Each channel includes current-sense FET-based overload detection, thermal shutdown at 140°C with 25°C hysteresis, and UVLO activation at ~2.0V.
Its soft-start circuit enforces controlled 0.6ms typical output rise time (CL = 1µF, RLOAD = 5Ω), while the integrated N-MOS discharge path activates only when disabled, providing 100Ω resistive discharge to clear residual VOUT capacitance without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V–5.5V: Supports full USB 2.0 bus voltage tolerance and 3.3V/5V system rail compatibility. |
| Continuous Current per Channel | 1.5A max: Sustained load capability under thermal limits at +85°C ambient. |
| RDS(ON) (typ) | 85mΩ @ 5V, 1.5A, +25°C: Minimizes conduction loss and self-heating in MSOP-8EP package. |
| Short-Circuit Response Time | 2µs: Enables rapid current limiting before fault energy damages downstream components. |
| FLG Blanking Time | 7ms typ: Suppresses false overcurrent flags during capacitor inrush without external RC networks. |
| Output Discharge Resistance | 100Ω: Provides defined discharge path for VOUT capacitors when disabled, eliminating floating nodes. |
| Enable Polarity | Active-Low (EN1/EN2): Matches legacy USB hub controller GPIO logic and simplifies level-shifting. |
Pinout & Package
AP2182AMPG-13 uses the MSOP-8EP (exposed pad) package: 3mm × 3mm body, 0.65mm pitch, thermal pad soldered to PCB ground plane for enhanced θJA = 75°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference and thermal pad connection point | Primary return path for power and logic; exposed pad must be connected to PCB GND for thermal integrity. |
| IN | Main power input supply node | Accepts 2.7V–5.5V source; feeds both internal high-side switches and bias circuitry. |
| EN1 | Channel 1 enable control (active-low) | Drives first P-MOS switch; low = enabled, high = disabled with discharge activation. |
| EN2 | Channel 2 enable control (active-low) | Independent control of second P-MOS switch; supports staggered power sequencing. |
| FLG1 | Open-drain fault indicator for Channel 1 | Asserts low on overcurrent/overtemperature after 7ms blanking; requires external pull-up. |
| FLG2 | Open-drain fault indicator for Channel 2 | Independent fault reporting enables per-port USB overcurrent diagnostics in hub designs. |
| OUT1 | Channel 1 regulated power output | Delivers switched 2.7V–5.5V to load; includes reverse-current blocking and discharge path. |
| OUT2 | Channel 2 regulated power output | Electrically isolated output; supports dual independent USB ports or redundant subsystems. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1/EN2 allow per-channel power sequencing, staggered wake-up, and fault isolation in multi-port systems. |
| Integrated output discharge | 100Ω internal discharge path clears VOUT capacitance within milliseconds when disabled - no external FET or resistor required. |
| 7ms deglitched FLG output | Eliminates false overcurrent alerts during hot-plug inrush transients, enabling reliable USB port status reporting. |
| Reverse-current blocking | Prevents backflow from loaded outputs into IN rail during power-down or fault conditions - critical for shared-bus architectures. |
| UVLO with 2.0V threshold | Ensures switch remains off until input stabilizes above USB minimum operating voltage, preventing brown-out misbehavior. |
Applications
| USB 2.0 Hub Power Management | Laptop Docking Station Rails |
|---|---|
|
Use Scenario: Dual-port USB 2.0 hub requiring independent overcurrent protection and hot-plug compliance per port. IC Role / Device Role: High-side power switch controlling VBUS delivery to each downstream port with per-port fault flagging.

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 |
|---|---|---|---|
| TCK107AG,314 (Toshiba) | Active-high enable, 1.2A continuous, 110mΩ RDS(ON), no integrated discharge. | Lacks output discharge and has lower current rating; requires external discharge FET for hot-swap compliance. | Select if active-high logic alignment is mandatory and discharge is handled externally. |
| TPS22965DRLR (TI) | Single-channel, 2A, 44mΩ RDS(ON), active-low enable, no FLG deglitch or thermal hysteresis spec. | Requires two devices for dual-channel use; lacks per-channel fault flagging and 7ms blanking. | Choose for ultra-low RDS(ON) in space-constrained single-rail designs where dual-channel integration is not needed. |
Compared with TCK107AG,314 and TPS22965DRLR, AP2182AMPG-13 uniquely integrates dual-channel active-low control, per-port FLG with 7ms deglitch, and on-die discharge - reducing BOM count and improving USB-compliant hot-plug reliability in compact consumer and industrial enclosures.

FAQ
What is the maximum continuous current per channel for AP2182AMPG-13?
The AP2182AMPG-13 supports 1.5A continuous current per channel at +85°C ambient temperature with proper PCB thermal design. Its 85mΩ typical RDS(ON) in the MSOP-8EP package ensures low conduction loss, and thermal shutdown at 140°C provides fail-safe protection during sustained overload.
Does AP2182AMPG-13 require external components for output discharge?
No. AP2182AMPG-13 includes an integrated 100Ω discharge path that activates automatically when EN1 or EN2 is de-asserted. This eliminates the need for external MOSFETs or resistors, simplifying layout and ensuring reliable VOUT capacitor discharge during power-down or hot-removal sequences.
How does the 7ms FLG blanking time improve system reliability?
The 7ms deglitch timeout on FLG1/FLG2 prevents false overcurrent assertions during normal capacitive inrush events - such as plugging a USB device - by ignoring transient spikes shorter than 7ms. This avoids unnecessary port disablement and enables accurate fault reporting only for sustained faults.
Can AP2182AMPG-13 be used in automotive applications?
AP2182AMPG-13 is not AEC-Q100 qualified and is specified for industrial temperature range (-40°C to +85°C). For automotive applications, Diodes offers AEC-Q100 qualified alternatives like the AP2280x series; contact Diodes technical support for PPAP-capable, IATF 16949-manufactured variants.
