Product details
Overview
AP2820FMMTR-G1 from BCD Semiconductor is a high-side power distribution switch with integrated N-channel MOSFET, charge pump, over-current protection (OCP), thermal shutdown, and deglitched open-drain FLAG output. It delivers 2.5A continuous load capability, 60mΩ RDS(ON), and operates from 2.7V–5.5V input, targeting USB-compliant hot-plug power management in notebook and motherboard applications.
For engineers reviewing the AP2820FMMTR-G1 datasheet, AP2820FMMTR-G1 pinout, AP2820FMMTR-G1 application, or AP2820FMMTR-G1 equivalent, key selection criteria include active-low enable logic, 2.5A current limit with fold-back short-circuit protection, UVLO threshold of 2.5V ±0.2V, and MSOP-8 package thermal resistance of 150°C/W.
Technical Context
The AP2820FMMTR-G1 implements a charge-pump–driven high-side N-MOSFET switch with soft-start to limit inrush current during turn-on. Its OCP uses current-sense feedback with fold-back behavior, reducing short-circuit current to 1.18A when VOUT = 0V.
Thermal shutdown activates at 150°C with 30°C hysteresis, and UVLO ensures operation only above 2.5V (rising) with 0.2V hysteresis. The FLAG pin asserts low after 5–15ms delay upon OCP or OTP fault, with 35–70mV low-level voltage at 5mA sink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 60 mΩ typical at VIN=5V, IOUT=2.5A - meets USB voltage-drop requirements under full load |
| Continuous Output Current | 2.5 A - guaranteed for E/F/G/H versions per datasheet ordering table |
| Enable Logic | Active-low - EN pin asserts switch ON when pulled low (VENL ≤ 1.0V) |
| Supply Voltage Range | 2.7 V to 5.5 V - supports single-supply USB 5V and low-voltage battery-backed systems |
| FLAG Response Delay | 5–15 ms - fixed deglitched latency from OCP/OTP event to FLAG assertion |
| Shutdown Current | 1.0 μA max - enables ultra-low-power system standby states |
| UVLO Threshold | 2.5 V ±0.2 V - prevents erratic switching during brown-out or cold-start conditions |
Pinout & Package
AP2820FMMTR-G1 is housed in an MSOP-8 package (4.70 × 3.10 mm, 0.65 mm pitch), optimized for space-constrained USB port power rails. Thermal resistance θJA is 150°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference for internal circuits and MOSFET source |
| 2, 3 | VIN | Input supply rail connection - dual-pin layout reduces IR drop and improves current handling |
| 4 | EN | Active-low enable input - logic low (≤1.0V) turns on switch; high-Z when floating |
| 5 | FLAG | Open-drain fault indicator - requires external pull-up; sinks current during OCP/OTP |
| 6, 7, 8 | VOUT | Switched output - triple-pin configuration lowers conduction resistance and thermal impedance |
Key Features
| Feature | Design Value |
|---|---|
| No reverse current flow | Prevents backfeed from VOUT to VIN when disabled - eliminates need for external blocking diode |
| Soft-start circuitry | 500 μs typical turn-on time - limits inrush current to protect upstream power sources and capacitors |
| Fold-back short-circuit protection | Reduces output short current to 1.18 A - sustains safe power dissipation during sustained faults |
| Output discharge resistor | Integrated 100–200 Ω pull-low on VOUT after shutdown - ensures rapid output discharge for safety and sequencing |
| UL & CB certified | UL File No. E339337 and Nemko CB Cert. NO62093 - validated for end-equipment safety compliance |
Applications
| USB Bus-Powered Hubs | Hot-Plug Notebook Power Rails |
|---|---|
|
Use Scenario: Distributing 5V power across four downstream USB ports with independent over-current detection. IC Role / Device Role / Timing Role: High-side switch enabling/disabling individual port power with FLAG-driven fault reporting to hub controller. Use Value: Prevents bus-wide shutdown during single-port overload; 2.5A rating supports BC1.2 charging loads. |
Use Scenario: Enabling 5V VCC rail to USB-C PD controller or Type-A port during system wake-from-sleep. IC Role / Device Role / Timing Role: Controlled power gate with soft-start and fast FLAG response to prevent brown-out during wake transitions. Use Value: 1.0μA shutdown current minimizes battery drain; MSOP-8 footprint fits tight PCB layouts near connectors. |
| Battery-Charger Input Switching | USB Self-Powered Hub Management |
|
Use Scenario: Isolating charger IC input from main system rail during charging termination or fault. IC Role / Device Role / Timing Role: High-side load switch with UVLO and thermal shutdown - ensures charger disconnects before battery overvoltage. Use Value: 150°C thermal shutdown protects against charger IC failure; 60mΩ RDS(ON) avoids voltage loss in charging path. |
Use Scenario: Managing power to USB hub controller and transceivers when host is disconnected. IC Role / Device Role / Timing Role: Active-low enable synchronizes with USB enumeration state; FLAG signals over-current to firmware for port disable. Use Value: Deglitched FLAG prevents false interrupts; 5–15ms delay allows transient surges without false triggering. |
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 |
|---|---|---|---|
| TI TPS2051BDBVR | 2.0A rated, SOIC-5 package, no integrated discharge resistor, no FLAG output | Lacks fault reporting and output discharge - requires external components for same functionality | Choose only if FLAG and auto-discharge are unnecessary and board space permits discrete implementation |
| ON Semi NIS5130MN3TXG | 2.5A rated, MSOP-8, includes FLAG but no integrated discharge resistor; higher RDS(ON) (85mΩ) | Requires external pull-down for VOUT discharge; higher conduction loss impacts USB voltage margin | Acceptable where FLAG suffices and 25mΩ extra RDS(ON) is tolerable in thermal budget |
Compared with TPS2051BDBVR and NIS5130MN3TXG, AP2820FMMTR-G1 uniquely integrates active-low enable, deglitched FLAG, output discharge resistor, and 60mΩ RDS(ON) in MSOP-8 - delivering complete USB-compliant hot-plug control with minimal BOM count.

FAQ
What is the function of the FLAG pin on AP2820FMMTR-G1?
The FLAG pin is an open-drain output that asserts low (≤70mV at 5mA sink) within 5–15ms of over-current or over-temperature events. It requires an external pull-up resistor and directly interfaces with USB host controllers or microcontrollers to trigger fault-handling routines without additional signal conditioning.
Does AP2820FMMTR-G1 support reverse current blocking when disabled?
Yes - the device blocks reverse current (VOUT > VVIN) with leakage under 1.0μA, eliminating the need for external reverse-blocking diodes. This feature is confirmed in Electrical Characteristics Table 7 (IREVERSE = 0.1–1.0μA) and applies across -40°C to 85°C ambient range.
How does the soft-start behavior affect inrush current in AP2820FMMTR-G1?
Soft-start limits output voltage slew rate, resulting in a typical 500μs turn-on time from EN activation to 90% VOUT. This reduces peak inrush current by controlling dV/dt across output capacitance, preventing upstream supply droop and contact arcing in hot-plug connectors - verified in Figure 20 and Typical Application Note 2.
Is the MSOP-8 package of AP2820FMMTR-G1 compatible with standard reflow profiles?
Yes - the MSOP-8 package (JEDEC MS-012AC) supports standard lead-free reflow profiles with peak temperature up to 260°C for 10 seconds, as specified in Absolute Maximum Ratings. Thermal resistance θJA = 150°C/W assumes JEDEC-standard 2-layer board layout with 1-in² copper pad.
