Diodes Incorporated AP2411AM8-13

Overview

AP2411AM8-13 from Diodes Incorporated is a single-channel, current-limited, high-side power switch with active-high enable, optimized for USB and hot-swap applications. It delivers 2.0A continuous load current, features 70mΩ R_DS(ON) at 5V, 2µs short-circuit response time, integrated output discharge, and latched-off overcurrent protection. It operates across 2.7V–5.5V input voltage and supports SO-8, MSOP-8, and U-DFN packages - used in USB hubs, docking stations, and embedded peripheral power control.

For engineers reviewing the AP2411AM8-13 datasheet, AP2411AM8-13 pinout, AP2411AM8-13 application, or AP2411AM8-13 equivalent, key selection criteria include latch-off OCP behavior, 7ms FLG deglitch timing, reverse current blocking, thermal shutdown threshold (140°C), and compatibility with heavy capacitive loads in USB-compliant hot-swap systems.

Technical Context

The AP2411AM8-13 integrates an N-channel MOSFET power switch with current-sense FET-based overcurrent detection, eliminating external sense resistors. Its internal deglitch circuit enforces a 7ms fault confirmation window before latching off, preventing false trips during inrush or transient overload.

It implements undervoltage lockout (UVLO) with 2.0V turn-on threshold and 50mV hysteresis, plus thermal shutdown at 140°C with 20°C hysteresis. The open-drain FLG pin reports both overcurrent and overtemperature faults after blanking, while the built-in discharge path (R_DIS = 105Ω) actively drains output capacitance when disabled.

Key Specifications

Pinout & Package

AP2411AM8-13 is packaged in MSOP-8 (8-pin, 3mm × 3mm, 0.65mm pitch) with exposed thermal pad. Pin 1 is GND; pins 2–3 are IN (must be tied externally); pin 4 is EN (active-high); pin 5 is FLG (open-drain fault flag); pins 6–7 are OUT (must be tied externally); pin 8 is NC (recommended tied to OUT). Exposed pad must be connected to PCB ground plane for thermal management.

FAQ

What is the difference between AP2401A and AP2411A?

AP2401A features active-low enable (EN low = ON), while AP2411A uses active-high enable (EN high = ON). All other electrical specifications - including 2.0A current rating, 70mΩ R_DS(ON), 2µs short-circuit response, and latch-off OCP - are identical. The part number suffix "M8" denotes MSOP-8 package, and "-13" indicates 2,500-unit tape-and-reel packaging.

Does AP2411AM8-13 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. An external pull-up resistor on FLG is needed for fault monitoring. For heavy capacitive loads (>100µF), a larger input capacitor (≥2.2µF) is recommended to suppress inrush-induced voltage spikes.

How does the latch-off behavior affect system recovery after overcurrent?

After overcurrent triggers the 7ms deglitch timer, AP2411AM8-13 latches OFF and holds OUT at 0V until either the EN pin is toggled (e.g., driven low then high) or input power is cycled. This prevents automatic retry into persistent faults - unlike auto-retry switches - and requires explicit host intervention or reset logic to restore power.

Can AP2411AM8-13 be used in dual-purpose HDMI/MHL ports?

Yes - its integrated discharge function safely clears residual output voltage when disabled, and reverse current blocking prevents peripheral battery drain during host sleep. However, ensure VIN ramps fully before enabling EN to avoid overstress on the discharge MOSFET during simultaneous data/charging operation.
