Product details
Overview
AP2191DMPG-13 from Diodes Incorporated is a single-channel, active-high enable, high-side USB power switch with integrated output discharge, 2.1A current limiting, 90mΩ RDS(ON) (U-DFN2018-6), and 7ms FLG deglitch-designed for hot-swap USB 2.0 ports in laptops, docking stations, and HUBs.
For engineers reviewing the AP2191DMPG-13 datasheet, AP2191DMPG-13 pinout, AP2191DMPG-13 application, or AP2191DMPG-13 equivalent, key selection criteria include enable polarity compatibility, thermal shutdown threshold (140°C), output discharge resistance (100Ω), and SO-8/MSOP-8/U-DFN2018-6 package options for board space and thermal optimization.
Technical Context
The AP2191D implements a thermally protected, slew-rate-controlled N-channel MOSFET gate driver with UVLO (1.9V typ), reverse-current blocking, and open-drain FLG reporting triggered by overcurrent or junction temperature >140°C. Its internal current sense FET enables accurate 2.1A trip without external resistors.
It features a dedicated 100Ω NMOS discharge path activated on EN deassertion, enabling rapid VOUT decay (e.g., <0.6ms for 10µF load), and integrates 7ms hardware deglitching on FLG to suppress false fault reporting during capacitive inrush transients-no external RC network required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.1A typical; clamps output current during overload to prevent damage to downstream circuitry |
| RDS(ON) | 90mΩ max (U-DFN2018-6, 5V, 25°C); minimizes conduction loss and self-heating at 1.5A continuous load |
| Input Voltage Range | 2.7V–5.5V; supports full USB 2.0 bus voltage range including low-voltage brownout conditions |
| Enable Polarity | Active High; simplifies interface with microcontroller GPIOs without level-shifting or inversion logic |
| FLG Blanking Time | 7ms typical; suppresses false fault flags during capacitor charging surges, eliminating need for external timing components |
| Output Discharge Resistance | 100Ω typical; provides controlled VOUT ramp-down (e.g., ~10ms for 100µF) when disabled, preventing backfeed |
| Thermal Shutdown Threshold | 140°C typical; disables output and asserts FLG to protect die during sustained short-circuit or overload |
Pinout & Package
AP2191DMPG-13 is packaged in U-DFN2018-6 (2.0mm × 1.8mm, 0.5mm pitch) with exposed thermal pad. The package supports high-density layout and enhanced thermal dissipation (θJA = 70°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Power Input | Connects to 2.7–5.5V supply rail; all IN pins tied together externally per datasheet |
| OUT | Switched Output | Delivers regulated power to load; dual pins (5 & 6) reduce trace resistance and improve current sharing |
| EN | Enable Control | Active-High digital input; drives internal gate driver; VIH ≥2V ensures TTL/CMOS compatibility |
| FLG | Fault Reporting | Open-drain output asserted low during overcurrent or thermal fault; 7ms deglitch prevents false triggers |
| GND | Ground Reference | Primary signal and power return; must be connected to PCB ground plane with low-impedance path |
| EP | Exposed Thermal Pad | Not electrically functional; must be soldered to GND copper pour with ≥4 thermal vias for optimal θJA |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Output Discharge | 100Ω internal NMOS path discharges external load capacitance rapidly upon disable-eliminates need for discrete discharge FET/resistor |
| Reverse Current Blocking | Prevents backflow from OUT to IN when VOUT > VIN and switch is off-critical for multi-rail systems with shared supplies |
| UVLO with Hysteresis | Turns on only when VIN ≥1.9V and remains on until VIN drops below ~1.6V-ensures clean power-up sequencing in hot-plug scenarios |
| Controlled Rise/Fall Time | 0.6ms typical turn-on rise time (CL=1µF, RL=10Ω); limits inrush current to <2.5A peak during hot-insertion |
| ESD Robustness | 4kV HBM / 300V MM rating-meets IEC61000-4-2 system-level ESD requirements without external protection diodes |
Applications
| USB 2.0 Port Protection | Laptop Docking Station Power Control |
|---|---|
|
Use Scenario: Protecting individual USB 2.0 downstream ports against short circuits, overloads, and hot-plug inrush. IC Role / Device Role / Timing Role: High-side power switch with current limiting, UVLO, and FLG fault reporting-acts as intelligent fuse and sequencer. Use Value: Enables safe hot-plug operation without damaging host controller or peripheral; 7ms FLG deglitch avoids false disconnects during plug-in transients. |
Use Scenario: Managing power delivery to multiple peripherals (HDMI, Ethernet, USB) via a single laptop docking station. IC Role / Device Role / Timing Role: Independent channel control for each port's VBUS rail, with discharge function ensuring clean power removal before unplug. Use Value: Prevents backfeed into dock when laptop is powered off; 100Ω discharge path clears 100µF loads in <10ms, meeting USB compliance discharge timing. |
| Desktop PC Front-Panel USB Hub | Set-Top Box Peripheral Interface |
|
Use Scenario: Isolating front-panel USB ports from motherboard power to avoid system reset during cable insertion/removal. IC Role / Device Role / Timing Role: Hot-swap controller with controlled 0.6ms rise time and thermal shutdown-delays full VBUS ramp to limit surge current. Use Value: Reduces peak inrush to ≤2.1A, preventing voltage droop on shared 5V rail and avoiding brownout resets of main system. |
Use Scenario: Power switching for USB-connected storage devices (e.g., external HDDs) in consumer set-top boxes. IC Role / Device Role / Timing Role: Load switch with reverse-current blocking and 140°C thermal cutoff-prevents backfeed from HDD's internal LDO into STB supply. Use Value: Eliminates need for external Schottky diode; 90mΩ RDS(ON) reduces power loss to <210mW at 1.5A, improving thermal margin in sealed enclosures. |
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 |
|---|---|---|---|
| TUSB2036IPWR | USB 2.0 hub controller with integrated power switches (3-port); not a standalone load switch-requires configuration via I²C | Designed for full hub functionality (data + power); lacks independent discharge control and 100Ω discharge path | Select when needing data switching + power control in one IC; avoid if only power switching is required |
| TPS2051BDBVR | Single-channel 1.5A USB power switch; active-high EN; 130mΩ RDS(ON); no integrated output discharge or reverse-current blocking | Requires external discharge FET/resistor and back-to-back MOSFETs for reverse blocking-increases BOM count and layout area | Select for cost-sensitive designs where discharge/reverse blocking are handled externally; verify thermal derating at 1.5A |
Compared with TUSB2036IPWR and TPS2051BDBVR, AP2191DMPG-13 delivers higher current capability (2.1A vs 1.5A), lower RDS(ON), and integrated discharge/reverse-blocking-reducing component count and improving reliability in compact USB power management.

FAQ
What is the maximum continuous load current supported by AP2191DMPG-13?
The AP2191DMPG-13 supports 1.5A maximum continuous load current per its Recommended Operating Conditions. Although its current-limit threshold is 2.1A typical, sustained operation above 1.5A requires careful thermal design due to RDS(ON) heating-especially in U-DFN2018-6 with θJA = 70°C/W.
Does AP2191DMPG-13 require external components for output discharge?
No. AP2191DMPG-13 integrates a 100Ω NMOS discharge path activated automatically when EN is deasserted. This eliminates the need for external FETs, resistors, or timing networks-verified in the datasheet's Typical Performance Characteristics (Discharge Time plot, page 7).
How does the 7ms FLG deglitch function impact system fault detection?
The 7ms deglitch prevents FLG assertion during brief inrush events (e.g., charging 120µF output caps), ensuring only sustained faults trigger host interrupt handling. Fault reporting remains accurate for real overloads while avoiding spurious disconnects-confirmed by the "Short Circuit with Blanking Time" waveform (page 6).
Can AP2191DMPG-13 be used in automotive USB applications?
AP2191DMPG-13 is rated for −40°C to +85°C ambient operation and meets USB 2.0 compliance, but it is not AEC-Q100 qualified. For automotive infotainment USB ports, use only in non-safety-critical cabin applications with additional system-level validation-Diodes does not specify automotive-grade qualification for this part.
