Product details
Overview
AP2192AFGEG-7 from Diodes Incorporated is a dual-channel, active-high enable, current-limited high-side power switch optimized for USB 2.0 and hot-swap applications. It delivers 2.0A typical per-channel current limiting, 85mΩ on-resistance (U-DFN3030-8 package), 2µs short-circuit response time, and integrated output discharge. It operates across 2.7V–5.5V input voltage and supports controlled 0.6ms rise time in LCD TV power rails and USB hub port protection.
For engineers reviewing the AP2192AFGEG-7 datasheet, AP2192AFGEG-7 pinout, AP2192AFGEG-7 application, or AP2192AFGEG-7 equivalent, this device is selected for robust overcurrent/overtemperature fault reporting with 7ms deglitching, reverse-current blocking, and ganged 4.0A short-circuit capability-critical for high-capacitance load management in embedded host-powered systems.
Technical Context
The AP2192AFGEG-7 integrates two independent P-MOS high-side switches with dedicated EN1/EN2 inputs and FLG1/FLG2 open-drain fault flags. Each channel features independent current sensing via internal sense FETs-not external resistors-enabling accurate 2.0A trip threshold and fast 2µs short-circuit detection without added path resistance.
Its thermal shutdown activates at 140°C with 25°C hysteresis, and UVLO disables switching below 2.0V input. The discharge function engages automatically upon disable, providing 100Ω resistive discharge path to safely bleed output capacitance-no external components required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit (per channel) | 2.0A typical - clamps output current during overload to prevent damage to downstream circuitry |
| On-Resistance (RDS(ON)) | 85mΩ max @ 5V, 1.5A - minimizes conduction loss and self-heating in U-DFN3030-8 package |
| Short-Circuit Response Time | 2µs - enables rapid current limiting before transient energy damages connected loads |
| FLG Blanking Time | 7ms typical - suppresses false fault reports during capacitive inrush without external RC networks |
| Input Voltage Range | 2.7V–5.5V - supports full USB 2.0 bus range and compatible with 3.3V/5V system rails |
| Operating Ambient Temp | −40°C to +85°C - qualified for industrial and consumer equipment environments |

Pinout & Package
AP2192AFGEG-7 is packaged in U-DFN3030-8 (Type E) with exposed thermal pad-requires connection to PCB ground plane for optimal thermal performance. Pin numbering follows top-view layout with pins 1–8 arranged counterclockwise starting from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (FLG1) | Channel 1 fault flag | Open-drain output pulled low during overcurrent or overtemperature; blanked for 7ms to reject inrush transients |
| 2 (OUT1) | Channel 1 power output | High-side switched output delivering up to 1.5A continuous load current with 85mΩ RDS(ON) |
| 3 (FLG2) | Channel 2 fault flag | Independent open-drain flag for second channel; identical timing and logic behavior as FLG1 |
| 4 (OUT2) | Channel 2 power output | Dual independent output enabling simultaneous or staggered control of two USB ports or subsystems |
| 5 (GND) | Power and signal ground | Common reference for all internal circuits; exposed pad must be soldered to GND for thermal integrity |
| 6 (EN2) | Channel 2 enable input | Active-high logic input; enables/disables OUT2 independently of EN1 |
| 7 (EN1) | Channel 1 enable input | Active-high logic input; allows individual sequencing of power-up/down for each channel |
| 8 (IN) | Main power input | Shared input rail for both channels; accepts 2.7V–5.5V with UVLO activation at ~2.0V |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 support asynchronous power sequencing-e.g., enable USB port A before B to manage inrush |
| Ganged short-circuit current limit | 4.0A typical when OUT1 and OUT2 are tied-enables coordinated protection for shared loads |
| Integrated output discharge | 100Ω internal discharge path activated on disable-eliminates need for external bleed resistors |
| Reverse-current blocking | Prevents backflow from VOUT to VIN when input is removed-critical for hot-plug safety |
| UL Recognized & IEC60950-1 CB certified | Meets safety standards for end-equipment certification without additional isolation components |

FAQ
What is the maximum continuous load current per channel for AP2192AFGEG-7?
The AP2192AFGEG-7 supports 1.5A maximum continuous load current per channel under recommended operating conditions (TA ≤ +85°C, VIN = 5.0V). Its 2.0A current-limit threshold triggers clamping during overload, but sustained operation above 1.5A risks thermal shutdown due to power dissipation in the U-DFN3030-8 package.
Does AP2192AFGEG-7 require external components for short-circuit protection?
No external components are required for basic short-circuit protection. The device integrates current-sensing FETs, 7ms FLG deglitching, thermal shutdown at 140°C, and automatic output discharge. Only input/output ceramic bypass capacitors (0.1–1µF) are recommended per datasheet for stability and transient immunity.
Can AP2192AFGEG-7 be used in automotive applications?
AP2192AFGEG-7 is not AEC-Q100 qualified and is specified for −40°C to +85°C ambient operation-suitable for commercial and industrial use but not automotive under hood or infotainment systems requiring extended temperature or PPAP compliance. Diodes offers AEC-Q100 variants (e.g., AP2192WQ) for such applications.
How does the output discharge function operate in AP2192AFGEG-7?
The discharge function activates automatically when EN1 or EN2 is de-asserted (low), or during power-up/power-down when VIN falls below UVLO (~2.0V). An internal 100Ω N-MOS switch connects OUTx to GND, discharging external capacitors without external resistors-ensuring safe, controlled voltage decay to prevent floating nodes or latch-up.
