Product details

Overview

AP2280-1WG-7 from Diodes Incorporated is a single-channel, slew-rate-controlled P-channel high-side load switch in SOT25 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 management in smartphones and Bluetooth headsets.

For engineers reviewing the AP2280-1WG-7 datasheet, AP2280-1WG-7 pinout, AP2280-1WG-7 application, or AP2280-1WG-7 equivalent, key selection criteria include controlled inrush suppression, ultra-low shutdown current, fast output discharge capability, and compatibility with 1.8V/2.5V/3.3V/5V rail sequencing in space-constrained portable designs.

Technical Context

The AP2280-1WG-7 integrates an internal slew-rate control circuit that limits dV/dt at the output to 100μs rise time (typical), reducing inrush current during hot-swap events. Its P-channel MOSFET structure enables high-side switching without external level-shifting, and the dedicated DIS pin allows active output discharge when EN is deasserted.

It supports wide-input operation (1.5V–6V) with logic-compatible enable thresholds (V_IL = 0.4V, V_IH = 1.4–1.7V depending on V_IN), operates across –40°C to +85°C ambient, and maintains R_DS(ON) < 105mΩ over full voltage range - ensuring stable conduction in multi-rail mobile SoC power domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	1.5V–6.0V - supports direct interface with 1.8V, 2.5V, 3.3V, and 5V system rails without regulation.
R_DS(ON) @ 5V	80mΩ typical - enables ≤2A load current with <160mV forward drop, minimizing power loss and thermal stress.
Turn-on Rise Time	100μs typical - actively limits inrush current to protect upstream power sources and downstream capacitors.
Quiescent Current	0.004μA typical - extends battery life in always-on subsystems such as GPS or Bluetooth standby circuits.
Output Discharge FET R_ON	20–40Ω - rapidly discharges output capacitance (<1ms) when disabled, preventing floating or latch-up states.
Operating Temperature	–40°C to +85°C - qualified for consumer portable equipment operating in real-world environmental conditions.

Pinout & Package

SOT25 (5-pin, surface-mount) package with exposed pad for thermal enhancement; JEDEC MO-203AA compliant, RoHS-compliant lead-free finish, green molding compound.

Pin/Terminal	Circuit Role	Design Meaning
DIS (Pin 1)	Output discharge control	When externally tied to OUT, activates internal discharge FET to pull output to GND during disable - prevents residual voltage hold-up.
GND (Pin 2)	Power ground reference	Primary return path for load current and internal bias; must be connected to low-impedance PCB ground plane.
OUT (Pin 3)	Switched output node	Drain of internal P-MOSFET; connects to load; requires 0.1μF local decoupling to stabilize transients.
IN (Pin 4)	Input power supply	Source of internal P-MOSFET; connects to main rail; requires 1μF local decoupling to suppress supply noise.
EN (Pin 5)	Active-high enable input	Logic-controlled gate driver; accepts 1.4–1.7V high threshold depending on V_IN; drives internal MOSFET gate directly.

Key Features

Feature	Design Value
Slew-rate controlled turn-on	Fixed 100μs rise time eliminates need for external RC timing networks in inrush-sensitive applications.
Ultra-low shutdown current	0.004μA ensures negligible battery drain during deep sleep modes in handheld devices.
Dedicated discharge pin (DIS)	Enables configurable output discharge without adding external MOSFETs or resistors - reduces BOM count and layout area.
Wide input voltage support	1.5V–6V operation covers all common logic and I/O supply rails, simplifying power architecture across mixed-voltage SoCs.
Thermally enhanced SOT25	θ_JA = 160°C/W enables 2A operation up to 74°C ambient - validated for compact PCB footprints in thin-profile devices.

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-MOS low-side driver; no slew control; 1.5V–18V input; 300mΩ R_DS(ON) per channel	Requires external high-side configuration; lacks integrated discharge; higher conduction loss	Select only if multi-load control and high-voltage tolerance (>6V) outweigh need for inrush control and low R_DS(ON).
TPS22915BYFPR	Single-channel, 1.5V–5.5V, 42mΩ R_DS(ON), 150μs slew rate, 0.5μA IQ, no DIS pin	No output discharge capability; slightly slower rise time; lower R_DS(ON) but higher quiescent current	Prefer when minimal conduction loss is critical and external discharge circuitry is acceptable.

Compared with TPL7407LDR and TPS22915BYFPR, AP2280-1WG-7 uniquely combines ultra-low IQ (0.004μA), integrated DIS functionality, and precise 100μs slew control in a 5-pin SOT25 - making it optimal for battery-critical, space-constrained, and inrush-sensitive portable power gating.

FAQ

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

The AP2280-1WG-7 supports up to 2A continuous load current under recommended operating conditions (T_A ≤ 74°C at V_IN = 5V). Actual current capability depends on ambient temperature, PCB copper area, and input voltage - at 85°C ambient and 5V input, safe continuous current drops to ~1.77A due to thermal limits defined by θ_JA = 160°C/W.

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

The DIS pin activates an internal discharge FET when externally connected to the OUT pin; this pulls the output to GND within ~1ms when EN is low. If DIS is left open, the output remains floating after disable - no discharge occurs, which may cause unintended behavior in downstream circuits relying on clean power-down reset.

Can AP2280-1WG-7 operate from a 1.5V supply, and how does R_DS(ON) change at low voltage?

Yes, AP2280-1WG-7 is fully specified down to 1.5V input. At 1.5V, R_DS(ON) increases to 200–250mΩ (typ/max), resulting in ~500mV drop at 2A - still functional for low-current loads like sensors or microcontrollers, but not recommended for high-current 1.5V rails without thermal derating.

Is the AP2280-1WG-7 pin-compatible with other variants in the AP2280 family?

Yes - all AP2280 variants (e.g., AP2280-2WG-7, AP2280-1FMG-7) share identical SOT25 pinout and terminal functions. The "-1" suffix denotes 100μs slew rate; "-2" denotes 1ms. Package variants (W vs FM) differ physically but maintain functional pin equivalence across IN, OUT, EN, GND, and DIS assignments.
