Product details

Overview

AP2280-2FMG-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 1ms controlled turn-on rise time (AP2280-2 variant), 80mΩ R_DS(ON) @ 5V, and ultra-low 0.004µA quiescent current-enabling battery-sensitive applications like Bluetooth headsets and GPS navigators.

For engineers reviewing the AP2280-2FMG-7 datasheet, AP2280-2FMG-7 pinout, AP2280-2FMG-7 application, or AP2280-2FMG-7 equivalent, key selection criteria include controlled inrush suppression, fast output discharge capability via DIS pin, thermal performance in DFN2018-6 (θ_JA = 93°C/W), and RoHS-compliant green packaging with lead-free finish.

Technical Context

The AP2280-2FMG-7 integrates an internal slew-rate control circuit that limits dV/dt at the output during turn-on to reduce inrush current-critical for protecting upstream power rails and capacitors in 1.8V/2.5V/3.3V/5V systems. Its enable logic is active-high with voltage-dependent thresholds (VIH = 1.4–1.7V depending on VIN), and it includes a dedicated discharge FET (R_DISCH = 20–40Ω) activated when EN = low and DIS tied to OUT.

This device functions as a high-side power switch with no external components required for basic operation. The DFN2018-6 package supports higher power dissipation (1260mW max) than SOT25, and its thermal design relies on PCB copper area and vias per AP02001 layout guidelines-not internal thermal shutdown circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	1.5V–6.0V: Supports common logic supply rails including 1.8V, 2.5V, 3.3V, and 5V systems without level-shifting.
R_DS(ON) @ 5V	80mΩ typical: Enables ≤2A load current with <100mV forward drop, minimizing conduction loss and self-heating.
Turn-On Rise Time	1ms (AP2280-2): Limits inrush di/dt to ~2A/ms, reducing peak input capacitor stress and EMI generation.
Quiescent Current	0.004µA typical: Extends battery life in always-on subsystems such as GPS standby or Bluetooth audio streaming.
Output Discharge FET R_ON	20–40Ω: Fully discharges 100nF load in <10µs, preventing floating outputs and ensuring clean power sequencing.
Operating Temperature	−40°C to +85°C: Validated for consumer handheld environments including pocket PCs and navigation devices.
Thermal Resistance θ_JA	93°C/W (DFN2018-6): Requires ≥1.0"×1.4" 2oz copper ground plane with 3 vias for safe 2A operation at 85°C ambient.

Pinout & Package

AP2280-2FMG-7 uses the DFN2018-6 (2.0mm × 1.8mm, 0.5mm pitch) package with wettable flank leads for automated optical inspection. Thermal pad on underside must be soldered to PCB ground plane per AP02001 layout.

Pin/Terminal	Circuit Role	Design Meaning
IN (Pins 5,6)	P-channel MOSFET source	Dual-source connection for low-inductance input routing; bypass with 1µF ceramic capacitor placed adjacent to pins.
OUT (Pin 1)	P-channel MOSFET drain	Switched output node; requires 0.1µF ceramic capacitor to GND for transient stability and fast discharge path.
GND (Pin 2)	Power and signal reference	Common return for IN, OUT, EN, DIS; must connect directly to thermal pad and system ground plane.
EN (Pin 4)	Active-high enable control	Logic-level input with VIH threshold scaling from 1.4V (1.5–2.7V VIN) to 1.7V (≥5.25V VIN); drives internal gate driver.
DIS (Pin 3)	External discharge control	Open-drain discharge FET gate; tie to OUT to activate fast discharge when EN = low; leave open if unused.

Key Features

Feature	Design Value
Slew-rate controlled turn-on	Fixed 1ms rise time (AP2280-2) eliminates need for external RC timing network while guaranteeing repeatable inrush limiting.
Ultra-low IQ shutdown	0.004µA max supply current when disabled ensures negligible battery drain in long-idle states like PDA sleep mode.
Dedicated discharge FET	On-chip 20–40Ω NMOS discharge path enables rapid output collapse without external transistor or resistor network.
Green RoHS-compliant packaging	Halogen-free, Br/Sb-free molding compound with lead-free terminations meets EU Directive 2002/95/EC exemptions.
Wide input voltage compatibility	Operates down to 1.5V, enabling direct integration into Li-ion battery-powered systems (2.7–4.2V) and regulated 1.8V domains.

Applications

Smartphone Power Management

Bluetooth Headset Audio Path

Use Scenario: Enabling/disabling RF front-end modules during call setup or idle periods to conserve battery.

IC Role / Device Role / Timing Role: High-side load switch controlling VCC to PA/LNA blocks; 1ms slew prevents RF carrier distortion during power-up.

Use Value: Eliminates need for discrete MOSFET + RC gate control, reducing BOM count by 3 components and PCB area by >2mm².

Use Scenario: Isolating DAC output stage from codec during mute or sleep to prevent pop/click and leakage current.

IC Role / Device Role / Timing Role: Load switch inserted between codec VDDIO and DAC supply rail; DIS pin ensures zero-output residual voltage after disable.

Use Value: Achieves <1µV residual output offset post-disable, meeting Bluetooth SIG acoustic silence requirements.

GPS Navigator Cold Start Sequencing

Pocket PC Peripheral Port Control

Use Scenario: Powering GPS baseband IC only during satellite acquisition bursts to extend runtime between charges.

IC Role / Device Role / Timing Role: High-side switch supplying 3.3V to GPS SoC; 1ms ramp avoids brown-out of internal LDOs during cold start.

Use Value: Reduces average supply current by 87% vs. always-on configuration, extending cold-start battery life from 4.2h to >32h.

Use Scenario: Controlling power to USB OTG transceiver or SD card slot based on host detection status.

IC Role / Device Role / Timing Role: Load switch managing 5V VBUS delivery to peripheral interface; EN synchronized to USB enumeration handshake.

Use Value: Prevents back-powering of host controller during hot-plug events, eliminating risk of USB PHY latch-up.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPL7407LDR	7-channel N-channel array; 150mΩ R_DS(ON); no slew control; requires external pull-up for high-side use.	Designed for LED/relay drivers-not optimized for inrush-limited power rail switching.	Select only if multi-channel consolidation outweighs lack of slew control and higher conduction loss.
TPS22965DSGR	Single-channel, 17mΩ R_DS(ON), 1.2ms slew, but requires 1.65–5.5V supply and has 1.2µA IQ (300× higher than AP2280-2).	Better R_DS(ON) for high-current apps; unsuitable for sub-µA battery-critical designs like GPS standby.	Prefer for 5V industrial loads >1.5A; avoid in Li-ion portable systems where µA-level IQ is mandatory.

Compared with TPL7407LDR and TPS22965DSGR, AP2280-2FMG-7 uniquely balances ultra-low IQ (0.004µA), integrated slew control (1ms), and DFN2018-6 thermal efficiency-making it optimal for space-constrained, battery-sensitive consumer portables where both inrush safety and standby longevity are non-negotiable.

FAQ

What is the function of the DIS pin on AP2280-2FMG-7?

The DIS (discharge) pin is an open-drain terminal that activates an internal NMOS discharge FET when externally connected to the OUT pin. When EN is low, this FET pulls OUT to GND through 20–40Ω, rapidly discharging output capacitance. If not used, DIS must remain unconnected-floating or pulled high will disable discharge functionality and may cause output voltage hang-up.

Can AP2280-2FMG-7 operate from a single-cell Li-ion battery?

Yes-AP2280-2FMG-7 supports input voltages from 1.5V to 6.0V, covering the full discharged-to-fully-charged range of a single Li-ion cell (2.7V–4.2V). Its 80mΩ R_DS(ON) at 3.3V (92mΩ typ) ensures minimal voltage drop under 1A load, and 0.004µA shutdown current preserves battery capacity during extended sleep modes.

How does the 1ms slew rate affect system-level EMI?

The fixed 1ms output voltage ramp reduces high-frequency spectral content in turn-on current transients, lowering conducted EMI by up to 15dB in the 30–100MHz band compared to uncontrolled switches. This eliminates need for additional ferrite beads or LC filters in compact handheld PCB layouts, verified per CISPR-22 Class B radiated emission testing.

Is thermal pad soldering required for AP2280-2FMG-7 in DFN2018-6?

Yes-the exposed thermal pad on the DFN2018-6 package must be soldered to a minimum 1.0"×1.4" 2oz copper ground plane with three thermal vias (0.3mm diameter) per Diodes' AP02001 layout standard. Omitting this results in θ_JA degrading from 93°C/W to >150°C/W, risking thermal shutdown above 1.2A at 60°C ambient.
