Product details
Overview
AP2111MPG-13 from Diodes Incorporated is a single-channel, active-high enable, high-side USB power switch with 2.45A current limiting, 90mΩ on-resistance (at 5V, 25°C), and integrated short-circuit/thermal protection. It operates from 2.7V–5.5V input, features 7ms deglitched open-drain FLG output, and supports hot-swap in USB 2.0-compliant host/port applications.
For engineers reviewing the AP2111MPG-13 datasheet, AP2111MPG-13 pinout, AP2111MPG-13 application, or AP2111MPG-13 equivalent, this device is selected for precise current-limited power delivery in space-constrained USB peripheral ports, thermal-critical docking stations, and systems requiring reverse-current blocking and auto-discharge without external components.
Technical Context
The AP2111 implements a monolithic N-channel MOSFET high-side switch with integrated current-sense FET architecture-eliminating external sense resistors while maintaining <±5% current-limit accuracy. Its UVLO threshold is fixed at 1.9V (typ), and thermal shutdown triggers at 140°C with 25°C hysteresis.
Control logic uses active-high EN with 2V minimum VIH, and fault reporting occurs via open-drain FLG with internal 7ms blanking to suppress false trips during capacitive inrush. The device delivers controlled 0.6ms (typ) rise time and 5μs short-circuit response, enabling robust hot-plug sequencing in USB HUBs and embedded peripherals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.45A typical; clamps load current precisely to prevent damage during overload or short circuit. |
| RDS(ON) | 90mΩ max at VIN=5V, IOUT=1.5A, TA=25°C; minimizes conduction loss and self-heating in compact layouts. |
| Input Voltage Range | 2.7V–5.5V; compatible with standard USB 2.0 bus voltage and wide-input industrial rails. |
| Enable Polarity | Active-high; simplifies interface with microcontrollers lacking active-low GPIO or level-shifting. |
| FLG Blanking Time | 7ms typical; suppresses false over-current flags during capacitor charging transients without external RC. |
| Shutdown Current | 1μA max; enables ultra-low-power standby in battery-backed or energy-sensitive systems. |
| Thermal Shutdown | 140°C trigger with 25°C hysteresis; provides autonomous recovery after fault removal without system intervention. |
Pinout & Package
AP2111MPG-13 is supplied in MSOP-8EP (Exposed Pad) package. The exposed pad must be soldered to PCB ground plane for thermal management but is not an electrical ground conduction path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; connects to PCB ground plane and exposed pad. |
| IN (pins 2,3) | Power input | Dual-pin configuration requires external tie-together; accepts 2.7–5.5V supply with UVLO protection. |
| EN | Enable control | Active-high logic input; asserts switch when ≥2V applied, disables at ≤0.8V. |
| FLG | Fault indicator | Open-drain output pulled low during over-current or over-temperature events after 7ms deglitch. |
| OUT (pins 6,7) | Switched output | Dual-pin configuration requires external tie-together; delivers current-limited power to load. |
| NC | No connection | Internally unconnected; recommended to tie externally to OUT for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-discharge function | 290Ω internal discharge resistor activates on disable, safely bleeding 120µF output caps in <500ms. |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled, eliminating need for external blocking diode. |
| Controlled rise/fall times | 0.6ms (typ) turn-on rise time and 0.03ms (typ) turn-off fall time enable clean hot-plug sequencing. |
| ESD robustness | 4kV HBM / 300V MM rating ensures reliability during board handling and end-user insertion cycles. |
| Green packaging | Halogen- and antimony-free, lead-free, RoHS-compliant MSOP-8EP package per EU Directive 2011/65/EU. |
Applications
| USB Host Port Protection | Hot-Swap Docking Station |

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 | 3-channel USB 2.0 transceiver with integrated 500mA switches; lacks 2.45A current limit and thermal shutdown. | Designed for USB hub IC integration-not standalone power switching. | Select only if full USB protocol handling and multi-port control are required alongside switching. |
| TPS2051BDBVR | Single-channel 500mA switch with 100mΩ RDS(ON); no auto-discharge, no reverse-current blocking, 1.5ms rise time. | Targeted at low-power USB peripherals; insufficient for 2A loads or hot-swap robustness. | Choose only for cost-sensitive, low-current (<500mA), non-hot-swap applications with minimal thermal constraints. |
Compared with TUSB2036IPW and TPS2051BDBVR, AP2111MPG-13 uniquely combines 2.45A current limiting, reverse-current blocking, auto-discharge, and 7ms deglitched FLG in a thermally optimized MSOP-8EP-making it the only fit for high-reliability, high-current USB port protection where discrete protection and thermal autonomy are mandatory.

FAQ
What is the maximum continuous load current supported by AP2111MPG-13?
The AP2111MPG-13 supports up to 2.0A continuous load current per its Recommended Operating Conditions. Although its current limit is 2.45A (typ), sustained operation above 2.0A risks thermal shutdown due to power dissipation in the MSOP-8EP package-even with proper PCB thermal vias-so 2.0A is the validated continuous rating.
Does AP2111MPG-13 require external components for basic USB port protection?
No external components are required for core functionality: UVLO, current limiting, thermal shutdown, FLG deglitch, and auto-discharge are all fully integrated. Only two ceramic bypass capacitors (0.1µF at IN and 0.01µF at OUT) are recommended for noise immunity-no sense resistors, pull-up resistors, or timing capacitors needed.
How does the FLG pin behave during a short-circuit event?
During a short circuit, the FLG pin remains high for the first 7ms (typical deglitch window), then pulls low and stays low until both over-current and over-temperature conditions are cleared. If the short persists, FLG stays asserted; upon fault removal, FLG returns high within microseconds-enabling immediate host-level fault acknowledgment without software polling delays.
Can AP2111MPG-13 be used with input voltages below 2.7V?
No-operation below 2.7V violates the Recommended Operating Conditions. At VIN < 2.7V, UVLO may deactivate unpredictably, current limit accuracy degrades, and RDS(ON) increases significantly. Below 1.9V, the device forcibly disables regardless of EN state. For sub-2.7V applications, consider dedicated low-voltage power switches like the AP22801.
