Diodes Incorporated AP2411MP-13

Overview

AP2411MP-13 from Diodes Incorporated is a single-channel, current-limited high-side power switch with active-high enable, designed 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 over-current protection. It operates across 2.7V–5.5V input voltage and supports robust system-level protection in laptop power rails and docking station load switching.

For engineers reviewing the AP2411MP-13 datasheet, AP2411MP-13 pinout, AP2411MP-13 application, or AP2411MP-13 equivalent, key selection criteria include latch-off OCP behavior, 7ms deglitch timing on FLG, thermal shutdown threshold (140°C), reverse current blocking, and compatibility with heavy capacitive loads up to 120µF in USB-compliant systems.

Technical Context

The AP2411MP-13 integrates an N-channel MOSFET power switch with current-sense FET-based over-current 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 under-voltage lockout (UVLO) with 2.0V turn-on threshold and 50mV hysteresis, thermal shutdown at 140°C with 20°C hysteresis, and a dedicated open-drain FLG pin that asserts low only after confirmed over-current or over-temperature events - not during startup or brief transients.

Key Specifications

Pinout & Package

AP2411MP-13 is packaged in MSOP-8EP (exposed pad), a thermally enhanced 3mm × 3mm surface-mount package with 0.65mm pitch. The exposed pad must be soldered to a PCB ground plane with thermal vias for optimal θ_JA = 92°C/W performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side current-limited power switch applications.

Compared with AP2411MP-13, AP2401MP-13 offers identical protection and thermal performance but mandates active-low control, while TCK112G sacrifices latch-off reliability and discharge capability for lower R_DS(ON) - making AP2411MP-13 optimal for USB-compliant, fault-isolated designs requiring deterministic shutdown.

FAQ

What happens after AP2411MP-13 latches off due to over-current?

Once latched off, the output remains disabled until either the EN pin is toggled (low-to-high transition) or the input power is cycled. The FLG pin stays low during latch-off and only releases after the fault condition clears and EN is reasserted. No automatic retry occurs - ensuring safety-critical isolation.

Does AP2411MP-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, and tying NC to OUT is recommended. The 7ms deglitch, output discharge, UVLO, and thermal shutdown are fully internal - no resistors, capacitors, or diodes needed.

How does the output discharge function behave during normal operation?

The discharge function activates only when the device is disabled (EN = low). It connects an internal 100Ω path from OUT to GND, discharging output capacitance to <0.5V within 0.6ms. During enabled operation, the discharge path is completely disconnected - no leakage or loading occurs on the live output rail.

Can AP2411MP-13 drive a 120µF load capacitor safely?

Yes - its 0.6ms soft-start rise time and 2.5A accurate current limit prevent inrush overshoot into 120µF loads. The datasheet explicitly validates operation with 120µF, 220µF, and 470µF capacitors at 2.5Ω load, confirming reliable hot-plug behavior without input rail collapse or false OCP triggering.
