Product details
Overview
AP2401MP-13 from Diodes Incorporated is a single-channel, current-limited high-side power switch optimized for USB and hot-swap applications, featuring 2.5A accurate current limiting, 70mΩ on-resistance at 5V, latch-off over-current protection, and integrated output discharge. It operates from 2.7V to 5.5V input, supports -40°C to +85°C ambient, and uses active-low enable logic.
For engineers reviewing the AP2401MP-13 datasheet, AP2401MP-13 pinout, AP2401MP-13 application, or AP2401MP-13 equivalent, this device delivers fast 2µs short-circuit response, 7ms deglitch-enabled fault reporting via open-drain FLG, reverse current blocking, and built-in soft-start with 0.6ms typical rise time - critical for robust USB port power management and capacitive load handling.
Technical Context
The AP2401MP-13 integrates an N-channel MOSFET with precision current-sense FET architecture to enable accurate 2.5A current limiting without external sense resistors. Its thermal shutdown triggers at 140°C with 20°C hysteresis, and UVLO activates at 2.0V (rising) with 50mV hysteresis.
It implements a latched-off fault mode after 7ms deglitch timeout upon over-current or over-temperature events, requiring EN toggle or power cycle for recovery. The integrated discharge path (100Ω typical) activates only when disabled, ensuring controlled VOUT capacitor discharge without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Current Limit | 2.5A typical; clamps output during overload to prevent damage to downstream circuitry |
| RDS(ON) | 70mΩ at VIN = 5V, IOUT = 2A; minimizes conduction loss and self-heating in compact layouts |
| Short-Circuit Response | 2µs; enables rapid current limiting before destructive energy accumulates |
| FLG Blanking Time | 7ms typical; suppresses false fault reporting during inrush or transient capacitive loads |
| Input Voltage Range | 2.7V–5.5V; matches standard USB 2.0/3.0 and 3.3V/5V system rails |
| Enable Polarity | Active-low; simplifies direct interface with microcontroller GPIOs asserting low to enable |
| Discharge Resistance | 100Ω typical; provides controlled VOUT discharge path when disabled, eliminating floating outputs |
Pinout & Package
AP2401MP-13 is housed in MSOP-8EP (exposed pad) package, offering enhanced thermal performance (θJA = 92°C/W) versus standard MSOP-8. The exposed pad must be externally connected to GND plane for optimal thermal dissipation but not used as primary electrical ground path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for internal circuitry and thermal pad connection point |
| IN | Power input | Accepts 2.7V–5.5V supply; requires local 0.1µF ceramic bypass to GND |
| EN | Enable control | Active-low digital input; toggling resets latched-off fault state |
| FLG | Fault reporting | Open-drain, active-low output asserted after 7ms deglitch on OCP/OTP |
| OUT | Switched output | Delivers current-limited power to load; all OUT pins tied together internally |
| NC | No connection | Internally unconnected; recommended to tie externally to OUT for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Latch-off over-current protection | Prevents repeated fault cycling by holding OFF until EN toggle or power reset - essential for stable USB enumeration |
| Integrated output discharge | 100Ω internal discharge path eliminates need for external bleed resistor, reducing BOM count and board space |
| Reverse current blocking | Prevents backflow from output to input during disable or VIN dropout - critical for multi-rail systems |
| Built-in soft-start | 0.6ms typical rise time limits inrush current into heavy capacitive loads (e.g., USB hubs, monitors) |
| 7ms deglitch on FLG | Rejects sub-7ms transients (e.g., plug-in spikes), avoiding spurious system-level fault interrupts |
Applications
| USB 2.0/3.0 Port Power Switching | LCD Monitor Power Sequencing |
|---|---|
Use Scenario: Providing individually controllable 5V power to multiple USB downstream ports on a laptop docking station. IC Role / Device Role / Timing Role: High-side power switch with current limiting and fault reporting, enabling per-port hot-plug detection and isolation. Use Value: Prevents bus-wide failure from single-port short; 2µs response and latch-off ensure host controller remains operational during fault. | Use Scenario: Managing power delivery to backlight and logic rails in a 24-inch LCD monitor with >1000µF bulk capacitance. IC Role / Device Role / Timing Role: Hot-swap power switch with controlled 0.6ms rise time and integrated discharge for safe power-down sequencing. Use Value: Eliminates voltage overshoot during turn-on and residual charge on turn-off, protecting display driver ICs and EMI filters. |
| Set-Top Box USB Peripheral Hub | eReader Charging Circuit Protection |
Use Scenario: Supplying regulated 5V to USB peripherals (keyboard, storage) in a residential gateway with shared power rail. IC Role / Device Role / Timing Role: Current-limited high-side switch with reverse current blocking and thermal shutdown. Use Value: Blocks backfeed from powered peripherals into main SoC rail; 140°C thermal cutoff prevents fire hazard under sustained overload. | Use Scenario: Isolating and protecting the USB charging path in an eReader with Li-ion battery and USB OTG capability. IC Role / Device Role / Timing Role: Latch-off power switch with UVLO (2.0V) and output discharge for safe battery disconnect during low-VIN conditions. Use Value: Ensures clean power removal when USB host disconnects; discharge function prevents phantom power drain during sleep mode. |
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 |
|---|---|---|---|
| AP2411MP-13 | Identical specs except active-high enable logic | Suitable where MCU GPIOs drive high to enable (e.g., legacy firmware or pull-up bias schemes) | Select when system control logic uses active-high signaling; pinout and thermal performance identical |
| TCK112G,LF | 2.2A limit, 90mΩ RDS(ON), no latch-off (auto-retry), 10ms deglitch | Preferred for non-critical loads requiring automatic recovery (e.g., peripheral docks), not USB-compliant hot-swap | Choose only if auto-retry behavior is acceptable and 2.5A/70mΩ performance margin is not required |
Compared with AP2411MP-13, the AP2401MP-13 offers identical protection and thermal performance but requires active-low enable assertion - making it ideal for systems with open-drain or push-pull low-active control. Versus TCK112G, it provides stricter USB compliance via latch-off and faster fault response, at the cost of manual fault reset.

FAQ
What is the purpose of the NC pin on AP2401MP-13?
The NC (No Connection) pin is internally unconnected but electrically and thermally isolated. Diodes Incorporated recommends tying it externally to the OUT net to improve noise immunity and reduce EMI coupling through parasitic capacitance. It must not be left floating in high-noise environments, nor connected to GND or IN.
Does AP2401MP-13 require external components for basic operation?
No external components are required for core functionality. A 0.1µF ceramic capacitor between IN and GND is mandatory for stability. Additional 120µF–470µF bulk capacitance on IN/OUT is recommended for heavy loads, and a 0.1µF ceramic on OUT improves short-circuit immunity - but none are needed for enable, fault reporting, or current limiting.
How does the latch-off behavior affect system recovery after over-current?
After triggering over-current protection, AP2401MP-13 remains latched off until either the EN pin is toggled (low→high→low for active-low logic) or VIN is fully cycled. This prevents uncontrolled re-attempts that could damage downstream loads. Recovery is deterministic and software-controllable via the enable signal, not automatic.
Can AP2401MP-13 be used in automotive applications?
AP2401MP-13 is rated for -40°C to +85°C ambient and qualified to UL/IEC60950-1, but it is not AEC-Q200 qualified or specified for automotive temperature ranges (-40°C to +125°C). Its thermal shutdown threshold (140°C) and package thermal resistance (92°C/W) make it unsuitable for under-hood use without derating and additional heatsinking beyond standard PCB layout.
