Diodes Incorporated AP2280-1FMG-7

Overview

AP2280-1FMG-7 from Diodes Incorporated is a single-channel, slew-rate-controlled P-channel high-side load switch in DFN2018-6 package, designed for power distribution in portable electronics. It operates from 1.5V–6V input, delivers ≤2A continuous current, features 80mΩ R_DS(ON) @ 5V, 100μs controlled turn-on rise time, and consumes only 0.004μA quiescent current - enabling low-power battery system management.

For engineers reviewing the AP2280-1FMG-7 datasheet, AP2280-1FMG-7 pinout, AP2280-1FMG-7 application, or AP2280-1FMG-7 equivalent, key selection criteria include controlled inrush suppression, ultra-low shutdown current, fast output discharge capability, thermal performance in DFN2018-6, and compatibility with 1.8V/3.3V/5V rail sequencing.

Technical Context

The AP2280-1FMG-7 integrates an internal slew-rate control circuit that limits dV/dt at the output during turn-on, reducing peak inrush current into capacitive loads. Its enable threshold (VIH = 1.4–1.7V) supports direct interfacing with 1.8V and higher logic families without level shifting.

It includes a dedicated DIS pin tied externally to OUT to activate an internal 20–40Ω discharge FET upon disable, ensuring rapid output voltage collapse. The device uses a P-channel MOSFET topology with source-connected to IN and drain to OUT, requiring no external bootstrap components.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous load current supported by AP2280-1FMG-7?

The AP2280-1FMG-7 supports up to 2A continuous load current under recommended operating conditions (T_A ≤ 74°C, V_IN = 5V, R_DS(ON) = 80mΩ). At 85°C ambient, derating applies: maximum safe current drops to ~1.77A due to thermal limits defined by θ_JA = 93°C/W and T_J(max) = 125°C.

How does the DIS pin function, and what happens if it is left unconnected?

The DIS pin activates an internal 20–40Ω discharge FET when externally tied to the OUT pin. When enabled, it pulls the output to GND within milliseconds after EN goes low. If left unconnected (floating or open), the discharge FET remains inactive and the output voltage decays only through load leakage or external bleed resistors - potentially causing undefined states in downstream circuitry.

Can AP2280-1FMG-7 operate from a 1.5V input supply?

Yes - AP2280-1FMG-7 is fully specified down to 1.5V input, with R_DS(ON) = 200–250mΩ and VIH = 0.4V minimum at V_IN = 1.5V. This enables use in ultra-low-voltage applications such as single-cell Li-ion or alkaline-powered peripherals, though load current capability decreases proportionally with reduced V_IN.

Is the DFN2018-6 package of AP2280-1FMG-7 compatible with standard reflow profiles?

Yes - the DFN2018-6 package is qualified for lead-free reflow per JEDEC J-STD-020 Rev. E, with peak temperature up to 260°C. The exposed thermal pad must be soldered to a solid copper thermal plane using ≥6 vias to inner ground layers to achieve rated θ_JA = 93°C/W and prevent thermal shutdown during sustained 2A operation.
