Product details
Overview
AP2820DMM-G1 from BCD Semiconductor Manufacturing Limited is a high-side power distribution switch with active-low enable and open-drain FLAG output, designed for USB-compliant hot-plug power control. It features 60 mΩ RDS(ON), 2.0 A continuous load capability, under-voltage lockout (2.5 V typ), and integrated thermal/over-current protection with fold-back short-circuit response. Used in notebook motherboard USB hubs and self-powered bus applications.
For engineers reviewing the AP2820DMM-G1 datasheet, AP2820DMM-G1 pinout, AP2820DMM-G1 application, or AP2820DMM-G1 equivalent, key selection criteria include active-low enable logic, MSOP-8 package footprint, 2.7–5.5 V supply range, 75 μA typical quiescent current, and deglitched FLAG signaling for USB controller fault reporting.
Technical Context
The AP2820DMM-G1 integrates an N-channel MOSFET with charge pump gate drive to achieve low on-resistance while operating from a 2.7–5.5 V input. Its active-low EN pin directly interfaces with standard USB host controllers requiring inverted logic for power sequencing.
Protection architecture includes fold-back current limiting (1.18 A short-circuit current), thermal shutdown at 150 °C with 30 °C hysteresis, UVLO (2.5 V threshold), and reverse-current blocking when disabled. The open-drain FLAG pin asserts low after 5–15 ms delay upon over-current or over-temperature fault detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 60 mΩ max at VIN = 5 V, IOUT = 2.0 A - ensures ≤120 mV drop at full load, meeting USB 2.0 voltage compliance. |
| Continuous Load Current | 2.0 A - guaranteed rating for D-version (AP2820Dxx) across –40°C to +85°C ambient. |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply operation from USB 3.3 V or 5 V rails without external regulation. |
| Quiescent Current | 75 μA typ - enables low-power standby in always-on USB ports without compromising system battery life. |
| FLAG Delay Time | 5–15 ms - provides noise-immune fault detection window before asserting open-drain low signal to host controller. |
| UVLO Threshold | 2.5 V typ with 0.2 V hysteresis - prevents erratic switching during brown-out or soft-start conditions. |
| Thermal Shutdown | 150 °C junction temperature with 30 °C hysteresis - protects MOSFET during sustained overload or poor PCB thermal design. |
Pinout & Package
AP2820DMM-G1 is housed in an MSOP-8 package (4.7 mm × 3.1 mm, 0.65 mm pitch), optimized for space-constrained USB port power routing on notebook motherboards and compact hub PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal protection circuits and charge pump return path. |
| 2, 3 | VIN | Input supply pins - paralleled for low-impedance connection to upstream 5 V rail or DC-DC output. |
| 4 | EN | Active-low enable input - pulled high via external resistor; drives low to activate switch and initiate soft-start. |
| 5 | FLAG | Open-drain fault indicator - requires external pull-up; sinks current when OCP or OTP occurs. |
| 6, 7, 8 | VOUT | Switched output terminals - paralleled to deliver regulated 5 V (or lower) to downstream USB device ports. |
Key Features
| Feature | Design Value |
|---|---|
| Soft-start circuitry | 500 μs turn-on time - limits inrush current to prevent USB port voltage sag during hot-plug events. |
| Load short protection | Fold-back current limit (1.18 A) - reduces power dissipation during sustained short-circuit, enabling safe auto-recovery. |
| No reverse current flow | Blocking when disabled - eliminates backfeed from VOUT to VIN, critical for multi-rail USB systems with shared grounds. |
| UL & CB safety certification | UL File E339337 and Nemko CB IEC60950-1 - satisfies regulatory requirements for end-product safety approval in consumer electronics. |
| Output shutdown pull-low resistor | Integrated 100–200 Ω discharge path (A/C/E/G versions) - ensures rapid VOUT discharge after disable, preventing floating outputs. |
Applications
| USB Bus-Powered Hubs | Notebook Motherboard USB Ports |
|---|---|

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 |
|---|---|---|---|
| Texas Instruments TPS2051BDBVR | SOIC-5 package, 100 mΩ RDS(ON), no FLAG output, fixed 1.5 A current limit. | Lacks fault reporting interface; requires external comparator for OCP indication. | Choose when FLAG signaling is unnecessary and board space permits larger SOIC-5 footprint. |
| ON Semiconductor NIS5132MN3T1G | MSOP-8, 70 mΩ RDS(ON), active-high enable only, no UVLO or fold-back protection. | Requires external UVLO circuit and lacks short-circuit fold-back behavior. | Choose only if active-high enable matches system logic and simplified protection suffices. |
Compared with TPS2051BDBVR and NIS5132MN3T1G, AP2820DMM-G1 uniquely combines MSOP-8 size, active-low enable, deglitched FLAG, fold-back short-circuit response, and USB-compliant 60 mΩ RDS(ON) - making it optimal for space-constrained, fault-aware USB power delivery.

FAQ
What is the logic polarity of the EN pin on AP2820DMM-G1?
The EN pin on AP2820DMM-G1 is active-low: the switch turns on when EN is pulled below 1.0 V (typical VENL) and turns off when EN rises above 1.6 V (typical VENH). This matches common USB host controller GPIO configurations requiring inverted enable signaling for port power sequencing.
Does AP2820DMM-G1 require an external pull-up resistor on the FLAG pin?
Yes - the FLAG pin is open-drain and must be externally pulled up to a logic-compatible voltage (e.g., 3.3 V or 5 V). A typical 10 kΩ resistor ensures proper logic-level translation to USB host controllers while limiting sink current to ≤5 mA during fault assertion.
Can AP2820DMM-G1 be used with 3.3 V input supply?
Yes - AP2820DMM-G1 operates across 2.7 V to 5.5 V, including 3.3 V nominal rails. At 3.3 V, RDS(ON) increases slightly but remains within USB voltage-drop limits for ≤2.0 A loads; UVLO still functions at 2.5 V, ensuring reliable startup.
Is the MSOP-8 package of AP2820DMM-G1 thermally adequate for 2.0 A continuous operation?
Yes - the MSOP-8 package has θJA = 150 °C/W. With 60 mΩ RDS(ON) and 2.0 A load, power dissipation is 240 mW, resulting in ~36 °C junction-to-ambient rise above 25 °C ambient - well below the 150 °C thermal shutdown threshold under standard PCB layout (2 cm² 1 oz copper).
