Product details
Overview
AP2141DMPG-13 from Diodes Incorporated is an active-low enable, single-channel high-side USB power switch with 0.8A current limiting, 90mΩ RDS(ON) (U-DFN2018-6), output discharge, and integrated thermal/over-current protection. It operates from 2.7V–5.5V input, features 7ms FLG deglitch, and is qualified for hot-swap in USB 2.0-compliant consumer and computing systems.
For engineers reviewing the AP2141DMPG-13 datasheet, AP2141DMPG-13 pinout, AP2141DMPG-13 application, or AP2141DMPG-13 equivalent, key selection criteria include enable polarity (active-low), output discharge capability, fault flag timing, thermal shutdown threshold (140°C), and package-specific RDS(ON) and θJA values for thermal design.
Technical Context
The AP2141DMPG-13 implements a controlled gate driver with slew-rate limiting to achieve 0.6ms typical rise time and suppress inrush current during hot-plug events. Its current-limiting architecture uses an internal sense FET-not an external resistor-to maintain low conduction loss while enabling accurate 0.8A trip threshold across temperature.
Thermal protection activates at 140°C junction temperature with 25°C hysteresis, forcing cyclic shutdown until fault removal. The open-drain FLG output reports over-current or over-temperature faults after 7ms blanking to reject transient spikes-no external RC network required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 0.8A typical; clamps sustained load current to prevent damage under overload or short-circuit conditions. |
| RDS(ON) | 90mΩ max (U-DFN2018-6 @ +25°C); enables low power loss and minimal voltage drop at 500mA continuous load. |
| Input Voltage Range | 2.7V–5.5V; supports full USB 2.0 bus voltage range and compatible with 3.3V/5V system rails. |
| Enable Polarity | Active-low; logic '0' on EN enables switch, simplifying interface with microcontrollers lacking active-high GPIO control. |
| FLG Blanking Time | 7ms typical; suppresses false fault reporting during capacitive load turn-on transients without external components. |
| Discharge Resistance | 100Ω typical; provides controlled output voltage decay when disabled, preventing floating or latch-up in downstream circuitry. |
| Shutdown Current | 1µA max; minimizes standby power draw in battery-powered or always-on USB peripheral applications. |
Pinout & Package
AP2141DMPG-13 is packaged in U-DFN2018-6: 2.0mm × 1.8mm, 0.5mm pitch, exposed thermal pad internally connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference and thermal pad connection | Must be externally soldered to PCB ground plane via thermal vias; primary path for heat dissipation and electrical return. |
| 2 (IN) | Main power input | Accepts 2.7V–5.5V supply; requires local 0.1µF ceramic bypass capacitor to suppress input transients. |
| 3 (EN) | Active-low enable control | Pulled low to enable switch; high-Z when un-driven; supports direct MCU GPIO interface without level-shifting. |
| 4 (FLG) | Open-drain fault indicator | Asserts low on over-current or over-temperature; requires external pull-up; 7ms deglitch prevents false triggering. |
| 5,6 (OUT) | Switched power output | Drives load directly; all OUT pins must be tied together externally; supports up to 500mA continuous current per spec. |
Key Features
| Feature | Design Value |
|---|---|
| Output Discharge Function | Internal 100Ω NMOS discharge path activated on disable, eliminating need for external bleed resistors in USB port designs. |
| Reverse Current Blocking | Prevents backflow from output to input when VOUT > VIN, critical for shared-bus or multi-rail systems where output may be pre-biased. |
| UVLO Protection | 1.9V turn-on threshold ensures switch remains off until input rail stabilizes, preventing erratic behavior during power ramp-up. |
| ESD Robustness | 15kV IEC 61000-4-2 contact discharge rating enables reliable operation in handheld and docking station environments. |
| Thermal Hysteresis | 25°C hysteresis between 140°C shutdown and recovery prevents oscillation during sustained overload, enabling safe fault-handling mode. |
Applications
| USB Hub Power Management | Laptop USB Port Protection |
|---|---|
|
Use Scenario: Individual port power control in multi-port USB 3.0/2.0 hubs to isolate faulty devices and comply with USB suspend/resume timing. IC Role / Device Role / Timing Role: High-side switch enforcing per-port current limit and providing FLG-based fault detection to host controller. Use Value: Enables automatic port disable on over-current, meeting USB 2.0 specification requirements for self-powered hubs without external sensing circuitry. |
Use Scenario: Hot-plug protection for Type-A USB ports on ultrabooks and 2-in-1 laptops handling peripherals like mice, keyboards, and flash drives. IC Role / Device Role / Timing Role: Active-low enable allows direct connection to EC (Embedded Controller) GPIO; 0.6ms rise time limits inrush during insertion. Use Value: Prevents system brown-out and protects upstream DC-DC converters by limiting peak surge current to <1.0A during plug-in events. |
| Set-Top Box USB Peripheral Interface | Gaming Console Accessory Port |
|
Use Scenario: Power switching for USB-connected storage drives, Wi-Fi adapters, or IR blasters in cable/satellite STBs operating in thermally constrained enclosures. IC Role / Device Role / Timing Role: Thermal shutdown (140°C) and 25°C hysteresis provide fail-safe response to prolonged 500mA loads in sealed plastic housings. Use Value: Eliminates need for external thermal sensors or fan control logic while maintaining compliance with IEC 60950-1 safety certification. |
Use Scenario: Power delivery to licensed accessories (e.g., racing wheels, VR headsets) via dedicated USB-C or Type-A accessory ports on gaming consoles. IC Role / Device Role / Timing Role: Output discharge function ensures rapid VOUT collapse when accessory is unplugged, preventing data corruption or handshake errors. Use Value: Guarantees clean power-off sequencing for USB enumeration restart, reducing accessory recognition failures during hot-swap cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side USB power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB2036IPW | Integrated USB 2.0 hub controller with embedded power switches; no standalone enable control or discharge function. | Requires full USB protocol stack support; not suitable for discrete power switching only. | Select when USB data routing + power control are co-located; avoid if only power gating is needed. |
| TPS2051BDBVR | Active-high enable, 1.5A current limit, no output discharge, 120mΩ RDS(ON) in SOT-23. | Lacks discharge and reverse-blocking; higher RDS(ON) increases dropout at 500mA. | Choose for cost-sensitive, non-USB-specific 5V rail switching where discharge is unnecessary. |
Compared with TUSB2036IPW and TPS2051BDBVR, AP2141DMPG-13 uniquely combines active-low enable, integrated discharge, reverse-current blocking, and 90mΩ RDS(ON) in a 2mm×1.8mm package-making it optimal for space-constrained, USB-compliant hot-swap designs requiring deterministic fault handling.

FAQ
What is the maximum continuous load current supported by AP2141DMPG-13?
The AP2141DMPG-13 is rated for 500mA maximum continuous load current under recommended operating conditions (TA = –40°C to +85°C, VIN = 2.7V–5.5V). This limit ensures thermal stability within the U-DFN2018-6 package's 70°C/W θJA and avoids triggering thermal shutdown during sustained operation.
Does AP2141DMPG-13 require external components for over-current fault filtering?
No. The AP2141DMPG-13 integrates a 7ms deglitch circuit on the FLG pin, which automatically suppresses transient over-current events-such as those caused by large output capacitance charging-without requiring external RC networks or firmware debouncing.
How does the output discharge function operate, and what is its design impact?
When EN is de-asserted, an internal 100Ω NMOS connects OUT to GND, discharging external capacitors. For a 100µF load, discharge time is ~6ms (t = R × C). This eliminates floating outputs and prevents unintended re-enumeration or latch-up in downstream USB PHYs after unplug.
Can AP2141DMPG-13 be used in dual-role USB ports (e.g., charging + data)?
No. Diodes' datasheet explicitly states the AP2141D/AP2151D series is not recommended for dual-purpose ports-such as HDMI/MHL or USB-C alternate modes-where simultaneous data transfer and battery charging occur. Its architecture lacks dynamic load-sharing or VBUS negotiation logic required for such applications.
