Product details
Overview
AP2182ASG-13 from Diodes Incorporated is a dual-channel, active-low-enable, current-limited high-side power switch optimized for USB 2.0 hot-swap and capacitive-load applications. It delivers 1.5A continuous per channel, features 85mΩ typical RDS(ON) (U-DFN3030-8), 2µs short-circuit response, integrated output discharge, and reverse-current blocking - deployed in LCD monitors, docking stations, and USB hubs.
For engineers reviewing the AP2182ASG-13 datasheet, AP2182ASG-13 pinout, AP2182ASG-13 application, or AP2182ASG-13 equivalent, key selection criteria include active-low enable logic, dual independent fault reporting via open-drain FLG pins, 7ms deglitch timing on overcurrent detection, and thermal shutdown at 140°C with 25°C hysteresis.
Technical Context
The AP2182ASG-13 integrates two independent P-channel MOSFET high-side switches with dedicated current-sense FETs, UVLO (2.0V threshold), and thermal shutdown circuitry. Each channel operates across 2.7V–5.5V input, supports soft-start (0.6ms typical rise time), and provides ganged overload current limiting up to 4.0A when outputs are tied.
Its functional block includes dual independent deglitched FLG outputs (7ms blanking), internal discharge N-MOS path (100Ω typical), and reverse-current blocking during disable. The SO-8 package variant has θJA = 115°C/W; U-DFN3030-8 achieves 60°C/W with exposed pad grounded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Count | Dual independent high-side power switches with separate EN/FLG pins |
| Enable Logic | Active low (EN1/EN2 asserted low); matches USB host controller reset-active-low signaling |
| Current Limit | 2.0A typical per channel; limits inrush and short-circuit current without external components |
| RDS(ON) | 85mΩ typical (U-DFN3030-8, 5V, 25°C); enables <125mW conduction loss at 1.5A |
| Short-Circuit Response | 2µs detection-to-limit activation; prevents system bus collapse during downstream shorts |
| FLG Blanking Time | 7ms typ; suppresses false fault reporting during capacitor charging transients |
| Discharge Resistance | 100Ω typical; actively discharges output capacitance when disabled, eliminating floating voltage |
Pinout & Package
AP2182ASG-13 is supplied in SO-8 package (JEDEC MS-012AC) with exposed pad thermally connected to GND. Pin 1 = FLG1, Pin 2 = OUT1, Pin 3 = FLG2, Pin 4 = OUT2, Pin 5 = GND, Pin 6 = EN2, Pin 7 = EN1, Pin 8 = IN. Exposed pad must be soldered to PCB ground plane for thermal performance and EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 8) | Main power input | Accepts 2.7–5.5V supply; feeds both channels; requires local 0.1–1µF ceramic bypass |
| EN1 / EN2 (Pins 7 / 6) | Active-low enable inputs | Directly interface with GPIOs or USB controller reset lines; no pull-up required |
| OUT1 / OUT2 (Pins 2 / 4) | Switched power outputs | Drive downstream loads (e.g., USB ports); support up to 1.5A continuous each |
| FLG1 / FLG2 (Pins 1 / 3) | Open-drain fault indicators | Assert low on overcurrent/overtemperature; 7ms deglitch eliminates false triggers from load caps |
| GND (Pin 5) | Power and signal reference | Return path for all channels and internal protection circuits; connects to exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent current limiting | Enables selective port shutdown in multi-port USB hubs without affecting other channels |
| Integrated output discharge | Eliminates need for external bleed resistors; ensures safe hot-plug removal by draining VOUT |
| Reverse-current blocking | Prevents backfeed from powered peripherals into main supply during fault or disable states |
| UVLO with 2.0V threshold | Guarantees clean power-up sequencing and prevents erratic switching during brown-out conditions |
| Thermal shutdown with hysteresis | 140°C trip + 25°C hysteresis enables self-recovery after transient overload without manual reset |
Applications
| USB 2.0 Hub Power Management | LCD Monitor Port Protection |
|---|---|
|
Use Scenario: Dual-channel USB hub supplying power to four downstream ports with individual overcurrent monitoring. IC Role / Device Role / Timing Role: High-side power switch providing per-port enable/disable, current limiting, and fault flagging to USB controller. Use Value: Enables compliance with USB 2.0 specification requiring 500mA per port and overcurrent reporting; 2µs response prevents bus lockup. |
Use Scenario: Power distribution to HDMI, USB, and audio interfaces in an LCD monitor with hot-plug capability. IC Role / Device Role / Timing Role: Dual-channel controlled power rail sequencer with soft-start and discharge for safe peripheral insertion/removal. Use Value: 0.6ms rise time prevents inrush-induced voltage droop on shared 5V rail; discharge function avoids residual voltage on disconnected ports. |
| Desktop Docking Station | Residential Gateway Power Control |
|
Use Scenario: Power switching for multiple peripherals (SSD, Ethernet, display) in a Thunderbolt/USB-C docking station. IC Role / Device Role / Timing Role: Dual high-side switch managing isolated 5V rails with independent fault reporting to system MCU. Use Value: Active-low EN simplifies connection to embedded controller GPIOs; 85mΩ RDS(ON) minimizes thermal load in compact enclosure. |
Use Scenario: Controlled power delivery to VoIP phone port, USB modem, and Wi-Fi module in residential gateway. IC Role / Device Role / Timing Role: Dual-channel protected power switch enabling firmware-controlled port enable/disable and fault isolation. Use Value: Reverse-current blocking prevents backfeed from PoE-powered devices into gateway's 5V supply; UL recognition supports safety certification. |
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 |
|---|---|---|---|
| AP2192ASG-13 | Identical specs except active-high enable logic (EN1/EN2 asserted high) | Required where host MCU GPIOs drive enable signals high-active (e.g., certain ARM-based SoCs) | Select when system-level enable polarity mandates high-true signaling; pinout and footprint identical |
| TCK127G,LF | Single-channel, 2.5A limit, 50mΩ RDS(ON), no integrated discharge, 10ms FLG blanking | Suitable only for single-rail applications; lacks dual independent FLG and discharge functionality | Use only when dual-channel independence is unnecessary and lower on-resistance outweighs missing features |
Compared with AP2192ASG-13, the AP2182ASG-13 offers identical protection and performance but requires inverted enable logic - critical for compatibility with legacy USB controllers. Versus TCK127G, it trades higher RDS(ON) for dual-channel autonomy, discharge, and tighter fault timing.

FAQ
What is the maximum continuous load current per channel for AP2182ASG-13?
The AP2182ASG-13 supports 1.5A continuous load current per channel under recommended operating conditions (TA ≤ +85°C, VIN = 2.7–5.5V). This rating accounts for thermal derating in SO-8 package; actual current may be limited by PCB layout and ambient temperature.
Does AP2182ASG-13 require external components for overcurrent protection?
No. The device integrates current-sense FETs, 2µs short-circuit detection, and 2.0A per-channel current limiting. Its 7ms FLG deglitch and built-in discharge path eliminate need for external resistors, capacitors, or diodes in standard USB 2.0 applications.
How does the output discharge function operate?
When EN1 or EN2 is de-asserted (high), an internal N-MOS transistor activates, providing a 100Ω resistive path from OUTx to GND. This drains stored charge from downstream capacitors within milliseconds, preventing unsafe residual voltage during hot removal.
Can AP2182ASG-13 be used in automotive applications?
The AP2182ASG-13 is not AEC-Q100 qualified. Diodes Incorporated offers automotive-grade variants (e.g., AP2182AQ) with PPAP support and IATF 16949 manufacturing; this part is intended for commercial/industrial USB and computing applications only.
