Product details
Overview
AP2820AMMTR-G1-01 from Diodes Incorporated is an obsolete 2.0A high-side power distribution switch with enable and fault flag, designed for USB power management. It integrates an N-channel MOSFET (RDS(ON) = 70 mΩ @ 5 V), charge pump, soft-start, overcurrent foldback protection, thermal shutdown, and undervoltage lockout (UVLO). It operates from 2.7 V to 6.0 V and delivers continuous 2.0 A load current in MSOP-8 package.
For engineers reviewing the AP2820AMMTR-G1-01 datasheet, AP2820AMMTR-G1-01 pinout, AP2820AMMTR-G1-01 application, or AP2820AMMTR-G1-01 equivalent, key selection criteria include guaranteed 2.0 A continuous current, deglitched open-drain FLAG output for OCP/OTP indication, USB-compliant voltage drop, and active-high enable with auto-discharge functionality in MSOP-8 footprint.
Technical Context
The AP2820AMMTR-G1-01 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 operation only above 2.7 V, while soft-start limits inrush current during hot-plug events.
Overcurrent protection uses foldback limiting (2.2 A min / 3.2 A max), and thermal shutdown activates at TJ ≥ +150 °C. The open-drain FLAG pin asserts low on overcurrent or overtemperature faults and requires an external pull-up resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 70 mΩ @ VIN = 5.0 V - meets USB voltage-drop requirements under full 2.0 A load |
| Continuous Current | 2.0 A - guaranteed output capability without derating at TA ≤ +85 °C |
| Current Limit Range | 2.2 A (min) to 3.2 A (max) - foldback reduces current during sustained overload |
| Supply Voltage Range | 2.7 V to 6.0 V - supports USB 5 V bus and lower-voltage battery-powered systems |
| Shutdown Current | <1 µA - enables ultra-low-power standby in portable applications |
| FLAG Output Type | Open-drain, deglitched - provides noise-immune fault signaling to USB controller |
| Enable Polarity | Active-high with auto-discharge - simplifies control interface and ensures safe turn-off |
Pinout & Package
AP2820AMMTR-G1-01 is packaged in MSOP-8 (3.0 mm × 4.9 mm, 0.65 mm pitch), optimized for space-constrained USB hub and notebook power rails.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal circuitry and MOSFET source |
| 2 | VIN | Main input supply (2.7–6.0 V); connects to upstream USB VBUS or battery rail |
| 3 | VIN | Second VIN connection - paralleled internally for reduced trace resistance and thermal stress |
| 4 | VOUT | Switched output; drives downstream USB port, hub IC, or peripheral load |
| 5 | VOUT | Second VOUT connection - paralleled internally to support 2.0 A continuous current |
| 6 | VOUT | Third VOUT connection - enhances current sharing and thermal dissipation |
| 7 | FLAG | Fault indicator output; open-drain, active-low on OCP/OTP/UVLO |
| 8 | EN/EN | Enable input; active-high logic level controls switch ON/OFF state |
Key Features
| Feature | Design Value |
|---|---|
| USB-compliant RDS(ON) | 70 mΩ at 5 V ensures ≤140 mV drop at 2.0 A - satisfies USB 2.0/3.0 voltage tolerance |
| Integrated soft-start | Controls MOSFET gate ramp rate to limit inrush current during hot-plug - prevents VBUS droop |
| Foldback overcurrent protection | Reduces output current to ~1.2 A during sustained overload - protects MOSFET and PCB traces |
| No reverse current flow | Body diode is blocked when disabled - eliminates backfeed from powered peripherals |
| UL recognition | UL-approved (File E172578) - supports safety certification of end equipment |
Applications
| USB Bus-Powered Hubs | Hot-Plug Notebook Power Rails |
|---|---|
Use Scenario: Distributing 5 V power across four downstream USB ports in a self-powered hub. IC Role / Device Role: High-side load switch enabling/disabling individual port power with fault reporting. Use Value: Prevents bus collapse during plug-in via soft-start; FLAG alerts host controller of short-circuit events. |
Use Scenario: Controlling auxiliary 5 V rail for ExpressCard or USB-C accessory slots in ultrabooks. IC Role / Device Role: Hot-swap power switch with UVLO and thermal protection for user-accessible connectors. Use Value: Ensures rail remains off below 2.7 V; foldback limits fault energy during accidental shorts. |
| Battery-Charger Interface | USB OTG Power Switching |
Use Scenario: Isolating charger IC output from system VBUS during battery charging cycles. IC Role / Device Role: Bidirectional isolation switch preventing backfeed from charged battery to charger input. Use Value: Zero reverse current eliminates leakage path - extends battery runtime and avoids charger latch-up. |
Use Scenario: Enabling VBUS output from mobile device during USB On-The-Go host mode. IC Role / Device Role: Controlled 5 V power delivery switch with fast fault response for OTG peripherals. Use Value: Deglitched FLAG provides reliable short-circuit detection within 10 µs - critical for OTG cable attach timing. |
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 | 2.1 A rated, RDS(ON) = 65 mΩ @ 5 V, same MSOP-8 package, active-high enable, no auto-discharge | Lacks auto-discharge; requires external RC network for controlled turn-off decay | Preferred where precise discharge timing is not required and lower RDS(ON) improves efficiency |
| AP22811BM8-13 | Same rating and package as AP22811AM8-13 but with active-low enable polarity | Requires inverted control signal; incompatible with existing AP2820AMMTR-G1-01 firmware logic | Select only when redesigning enable interface and prioritizing pin-for-pin replacement over logic compatibility |
Compared with AP2820AMMTR-G1-01, AP22811AM8-13 offers lower conduction loss but removes auto-discharge - impacting transient behavior during disable; AP22811BM8-13 retains performance but changes enable polarity, requiring hardware or firmware adaptation.

FAQ
Is AP2820AMMTR-G1-01 still in production?
No - AP2820AMMTR-G1-01 is officially obsolete and discontinued per Diodes Incorporated's EOL notice (DS41255 Rev. 1–4, September 2018). Aetrix Electronics maintains limited legacy stock for last-time buy and design continuity support, but no new production is planned.
What is the function of the EN/EN pin on AP2820AMMTR-G1-01?
The EN/EN pin is an active-high enable input that controls the MOSFET gate drive. When pulled high (≥2.0 V), the switch turns on; when low (<0.8 V), it disables with auto-discharge - actively discharging VOUT capacitance through an internal path to prevent floating output states.
Can AP2820AMMTR-G1-01 be used in automotive applications?
No - AP2820AMMTR-G1-01 is specified for −40 °C to +85 °C ambient operation and lacks AEC-Q100 qualification, automotive-grade screening, or extended temperature range. It is intended for commercial computing and consumer USB applications only.
How does the FLAG pin behave during overtemperature events?
The FLAG pin asserts low (open-drain sink) within 10 µs of detecting either overcurrent or overtemperature conditions. It remains low until the fault clears and the device resets - no external reset is required, but the enable must be cycled to restore normal operation after thermal shutdown recovery.
