Product details
Overview
AP2401FGE-7 from Diodes Incorporated is a single-channel, current-limited high-side power switch optimized for USB and hot-swap applications. It features 2.5A accurate current limiting, 70mΩ typical RDS(ON) at 5V, latch-off over-current protection with 7ms deglitch, and integrated output discharge. Designed for 2.7V–5.5V input operation, it delivers robust short-circuit response (2µs) and reverse current blocking in U-DFN3030-8 package.
For engineers reviewing the AP2401FGE-7 datasheet, AP2401FGE-7 pinout, AP2401FGE-7 application, or AP2401FGE-7 equivalent, key selection criteria include latch-off OCP behavior, active-low enable logic, thermal shutdown threshold (140°C), UVLO (2.0V typ), and compatibility with heavy capacitive loads in space-constrained USB port designs.
Technical Context
The AP2401FGE-7 implements an N-channel MOSFET high-side switch with internal current-sense FET architecture-eliminating external sense resistors while maintaining low conduction loss. Its protection stack includes simultaneous over-current detection (via ITRIG = 2.5A), thermal shutdown (140°C with 20°C hysteresis), and under-voltage lockout (2.0V rising, 50mV hysteresis).
Functional behavior is defined by its latched fault state: after 7ms deglitch timeout during over-current or over-temperature events, FLG asserts low and the switch remains off until EN toggle or power cycle. The integrated discharge path (RDIS = 100Ω, TDIS = 0.6ms) actively sinks output capacitance when disabled, preventing floating rail issues in hot-plug systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit Threshold | 2.5A typical; clamps load current to prevent damage during sustained overload or short circuit. |
| RDS(ON) | 70mΩ @ 5V, 25°C; enables <100mW conduction loss at 2A, reducing thermal stress in compact layouts. |
| Short-Circuit Response Time | 2µs; detects and initiates current limiting before transient energy damages downstream components. |
| UVLO Threshold | 2.0V (rising); prevents erratic turn-on during brown-out or hot-insertion ramp-up, ensuring clean power sequencing. |
| FLG Blanking Time | 7ms typical; suppresses false fault reporting from inrush or capacitive transients without external RC filtering. |
| Discharge Resistance | 100Ω; provides controlled VOUT decay (<0.6ms to <0.5V) when disabled, eliminating residual voltage hazards. |
| Thermal Shutdown | 140°C junction temperature; protects die integrity during prolonged overload, with 20°C hysteresis for stable recovery. |
Pinout & Package
AP2401FGE-7 is housed in a 3.0mm × 3.0mm × 0.55mm U-DFN3030-8 package with wettable flank leads and exposed thermal pad. The package supports high-density PCB layouts and enhanced thermal dissipation (θJA = 84°C/W with recommended layout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for power and signal; must be connected to PCB ground plane with low-inductance routing. |
| IN | Power input | Accepts 2.7V–5.5V supply; requires ≥0.1µF ceramic bypass capacitor placed adjacent to pin. |
| EN | Enable control | Active-low logic input; drives switch ON when pulled low (≤0.8V), OFF when high (≥2V). |
| FLG | Fault reporting | Open-drain output asserting low during OCP/OTP faults; requires external pull-up for system monitoring. |
| OUT | Switched output | Delivers regulated power to load; all OUT pins must be externally tied together for parallel current handling. |
| NC | No internal connection | Not bonded internally; recommended to tie to OUT for mechanical stability and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off over-current protection | Guarantees fail-safe shutdown after 7ms deglitch-prevents repeated fault cycling in persistent short conditions. |
| Integrated output discharge | 100Ω internal discharge path ensures rapid, controlled VOUT collapse (<0.6ms) when disabled, eliminating floating bus risks. |
| Reverse current blocking | Prevents backflow from VOUT to VIN when disabled (IREV ≤ 1µA at VOUT = 5V), critical for multi-rail USB systems. |
| Built-in soft-start | 0.6ms typical rise time limits inrush current into large capacitive loads, avoiding input rail collapse. |
| UL Recognized & RoHS compliant | Meets UL File E322375 and IEC60950-1 CB Scheme; halogen/antimony-free "Green" compound per Diodes' specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-side current-limited power switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2411FGE-7 | Identical specs except active-high enable logic (vs. AP2401's active-low); same package, RDS(ON), OCP, and thermal performance. | Requires inverted enable signal timing; suitable where MCU GPIO defaults to high or system logic favors active-high control. | Select when system-level enable polarity aligns with active-high; no change needed in protection or thermal design. |
| TCK107AG,LF | Lower current limit (1.5A), higher RDS(ON) (120mΩ), no latch-off (auto-retry), smaller U-DFN2020-6 package. | Targeted at lower-power USB peripherals; lacks latch-off behavior-may cause repeated fault cycling in persistent shorts. | Choose only for cost-sensitive, low-current (<1.2A) applications where auto-retry is acceptable and board space is extremely constrained. |
Compared with AP2411FGE-7, AP2401FGE-7 offers identical protection and thermal behavior but simplifies interface to MCUs with open-drain or active-low reset outputs; versus TCK107AG,LF, it delivers 67% higher current capacity, 42% lower on-resistance, and deterministic latch-off-critical for mission-critical USB power domains.

FAQ
What is the function of the NC pin on AP2401FGE-7?
The NC (No Connection) pin on AP2401FGE-7 has no internal bond wire or circuit connection. Diodes Incorporated recommends tying it externally to the OUT net to improve mechanical stability during reflow and reduce potential EMI coupling through floating metal. It must not be left floating in production designs.
Does AP2401FGE-7 require external components for over-current protection?
No. AP2401FGE-7 integrates all over-current protection functions-including current sensing via internal FET, 7ms deglitch timing, latch-off control, and FLG reporting-without requiring external resistors, capacitors, or comparators. Only a 0.1µF IN-to-GND ceramic capacitor and optional pull-up on FLG are needed for basic operation.
How does the output discharge function operate during enable de-assertion?
When EN is de-asserted (driven high), the internal discharge FET activates, connecting OUT to GND through a 100Ω path. This discharges external output capacitance to <0.5V within 0.6ms (CL = 1µF), ensuring safe hot-removal of peripherals and preventing back-powering of upstream circuitry.
Can AP2401FGE-7 be used in automotive applications?
AP2401FGE-7 is specified for -40°C to +85°C ambient operation and qualified to industrial reliability standards, but it is not AEC-Q100 qualified. For automotive infotainment USB ports or body-control modules, use only after full system-level validation-including extended temperature cycling, EMC, and fault injection testing-per OEM requirements.
