Product details
Overview
AP2820EMMTR-G1 from Diodes Incorporated is a discontinued 2.0A high-side power distribution switch with enable and fault flag, designed for USB-compliant hot-plug power control. It integrates an N-channel MOSFET (RDS(ON) = 70 mΩ @ 5 V), charge pump, soft-start, overcurrent foldback protection, thermal shutdown, undervoltage lockout (UVLO), and open-drain FLAG output-enabling robust USB bus/hub power management in notebook and motherboard applications.
For engineers reviewing the AP2820EMMTR-G1 datasheet, AP2820EMMTR-G1 pinout, AP2820EMMTR-G1 application, or AP2820EMMTR-G1 equivalent, key selection criteria include guaranteed 2.0A continuous load capability, 2.7–6.0 V operating range, <1 µA shutdown current, deglitched open-drain fault flag, and SOIC-8/MSOP-8/SOT-23-5 package compatibility with USB voltage-drop compliance.
Technical Context
The AP2820EMMTR-G1 implements a high-side switching architecture using an integrated N-channel MOSFET driven by an internal charge pump, eliminating external gate drive components. Its UVLO ensures activation only above 2.7 V, while soft-start limits inrush current during turn-on to protect upstream sources and downstream loads.
Overcurrent protection employs foldback limiting (2.2–3.2 A trip range), and thermal shutdown activates at TJ ≥ +150 °C. The open-drain FLAG pin asserts low on overcurrent or overtemperature events, requiring an external pull-up resistor for interface with USB controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 70 mΩ @ VIN = 5.0 V - meets USB 2.0 voltage drop requirements under full 2.0A load. |
| Continuous Current | 2.0 A - guaranteed output current capacity without derating at TA ≤ +85 °C. |
| Current Limit Range | 2.2 A (min) to 3.2 A (max) - foldback-type overcurrent protection with defined trip window. |
| Operating Voltage | 2.7 V to 6.0 V - supports USB 5 V, battery-backed, and low-voltage logic-compatible systems. |
| Shutdown Current | <1 µA - enables ultra-low-power state retention in portable and always-on USB hubs. |
| FLAG Output Type | Open-drain, deglitched - provides noise-immune fault signaling to microcontrollers or USB host controllers. |
| Thermal Shutdown | Activates at TJ ≥ +150 °C - prevents permanent damage during sustained overload or poor PCB thermal design. |
Pinout & Package
AP2820EMMTR-G1 is packaged in MSOP-8 (3.0 mm × 4.9 mm, 0.65 mm pitch). Pin functions are validated per Diodes DS41255 Rev. 1–4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (MSOP-8) | GND | Power ground reference for internal circuitry and MOSFET source return path. |
| 2 (MSOP-8) | VIN | Main input supply rail (2.7–6.0 V); connects to upstream power source such as USB VBUS. |
| 3 (MSOP-8) | VIN | Second VIN connection - paralleled with Pin 2 to reduce trace resistance and improve current sharing. |
| 4 (MSOP-8) | VOUT | Switched output node; connects to downstream load (e.g., USB port power rail). |
| 5 (MSOP-8) | FLAG | Active-low, open-drain fault indicator - requires external pull-up to signal OCP/OTP to host controller. |
| 6 (MSOP-8) | EN/EN | Enable input with configurable polarity (active-high or active-low per variant suffix); controls MOSFET gate drive. |
| 7 (MSOP-8) | VOUT | Secondary VOUT connection - paralleled with Pin 4 to minimize conduction loss and thermal stress. |
| 8 (MSOP-8) | VOUT | Third VOUT connection - used for high-current routing and thermal spreading across multiple pins. |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 70 mΩ at 5 V ensures ≤100 mV drop at 2.0 A, satisfying USB 2.0 specification for bus-powered devices. |
| Soft-start control | Internally controlled slew rate limits inrush current during power-up, preventing VBUS sag and system reset. |
| No reverse current flow | Body diode is blocked during shutdown - eliminates backfeed from powered downstream loads into upstream source. |
| UVLO threshold | 2.7 V minimum input ensures reliable turn-off during brownout or weak battery conditions. |
| Thermal foldback | Reduces current limit progressively under thermal stress to sustain operation below TJ = +150 °C. |
Applications
| USB Bus-Powered Hubs | Hot-Plug Notebook Power Rails |
|---|---|
Use Scenario: Distributing clean, protected 5 V power from a single upstream USB port to multiple downstream ports in a self-powered hub. IC Role / Device Role / Timing Role: High-side power switch managing load connection/disconnection with fault monitoring and current limiting. Use Value: Prevents VBUS collapse during plug-in of high-capacitance peripherals via soft-start and foldback OCP. |
Use Scenario: Enabling/disabling auxiliary 5 V rails (e.g., USB-C PD sink paths or card reader supplies) in ultrabooks during sleep/wake transitions. IC Role / Device Role / Timing Role: Controlled power gate with fast enable/disable and thermal-aware current limiting. Use Value: Achieves <1 µA quiescent current in standby, preserving battery life without sacrificing fault visibility. |
| Battery-Charger Input Switching | USB Self-Powered Peripheral Management |
Use Scenario: Isolating charger IC input from system battery during charging termination or fault conditions to prevent reverse leakage. IC Role / Device Role / Timing Role: Reverse-current-blocking high-side switch with UVLO and thermal protection. Use Value: Eliminates need for external Schottky diode or PMOS, reducing BOM count and forward voltage loss. |
Use Scenario: Powering USB audio interfaces or HID devices from host PC while detecting overcurrent faults before USB enumeration completes. IC Role / Device Role / Timing Role: Fault-flagged power delivery element interfacing directly with USB controller GPIOs. Use Value: Deglitched FLAG output enables reliable firmware-level fault recovery without false triggers from transient surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP22811AM8-13 | Lower RDS(ON) (45 mΩ), 2.5 A continuous rating, same 2.7–6.0 V range, integrated auto-discharge. | Supports higher current USB-C applications and faster discharge of output capacitance after disable. | Select when upgrading from AP2820 for improved efficiency or tighter thermal margins. |
| AP22811BM8-13 | Same electrical specs as AP22811AM8-13 but without auto-discharge function; otherwise identical pinout and protection features. | Suitable where rapid VOUT discharge is unnecessary (e.g., non-capacitive loads or systems with external bleed resistors). | Choose for cost-sensitive designs where auto-discharge adds no functional benefit. |
Compared with AP2820EMMTR-G1, both AP22811 variants offer lower on-resistance and higher current capability, with AP22811AM8-13 adding auto-discharge for faster turn-off transients-making them direct functional upgrades for new designs requiring enhanced USB power delivery robustness.

FAQ
Is AP2820EMMTR-G1 still in production?
No. AP2820EMMTR-G1 is obsolete and discontinued per Diodes Incorporated's official EOL notice (DS41255 Rev. 1–4, September 2018). Aetrix Electronics maintains limited legacy stock for replacement and repair use only, with no future manufacturing commitment.
What is the correct replacement part number for AP2820EMMTR-G1?
Diodes Incorporated recommends AP22811AM8-13 or AP22811BM8-13 as direct replacements. Both are pin-compatible with the MSOP-8 footprint, share identical enable/flag logic, and improve on RDS(ON), current rating, and thermal performance.
Does AP2820EMMTR-G1 support reverse current blocking?
Yes. The device blocks reverse current flow from VOUT to VIN when disabled, due to internal MOSFET body diode isolation and control circuitry-eliminating need for external reverse-blocking diodes in battery-charger or dual-supply applications.
What is the purpose of the deglitched FLAG output?
The deglitched FLAG output suppresses sub-millisecond noise spikes during switching transients, ensuring only sustained overcurrent or overtemperature events trigger the active-low fault signal-reducing false interrupts to USB host controllers and improving system reliability.
