Product details
Overview
AP2280-2WG-7 from Diodes Incorporated is a single-channel, slew-rate-controlled high-side load switch based on a P-channel MOSFET, designed for power distribution in portable electronics. It operates from 1.5V to 6V input, delivers ≤2A continuous current, features 1ms controlled turn-on rise time (AP2280-2 variant), 80mΩ typical RDS(ON) at 5V, and ultra-low 0.004µA quiescent current - enabling precise inrush current limiting in battery-powered 3.3V/5V subsystems.
For engineers reviewing the AP2280-2WG-7 datasheet, AP2280-2WG-7 pinout, AP2280-2WG-7 application, or AP2280-2WG-7 equivalent, key selection criteria include controlled slew rate for inrush suppression, fast discharge capability via DIS pin, thermal performance in SOT25 package, and compatibility with low-voltage logic enable thresholds across 1.5–6V supply rails.
Technical Context
The AP2280-2WG-7 integrates an internal slew-rate control circuit that limits dV/dt at the output during turn-on, reducing peak inrush current by extending rise time to 1ms (vs. 100µs for AP2280-1). This is achieved without external components and remains stable across 1.5–6V input range and −40°C to +85°C ambient.
It uses a P-channel MOSFET topology with source tied to IN, drain to OUT, and includes dedicated DIS pin for active output discharge when EN is low. The EN pin accepts logic-high enable thresholds scaling with VIN (1.4V min at 1.5–2.7V, 1.6V at 2.7–5.25V), ensuring robust interfacing with diverse microcontroller I/O levels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 1.5V – 6.0V: Supports direct integration into 1.8V, 2.5V, 3.3V, and 5V rail systems without level-shifting. |
| RDS(ON) @ 5V | 80 mΩ typical: Enables ≤2A load current with <0.16V dropout at full load, minimizing power loss and heat generation. |
| Turn-on Rise Time | 1000 µs (AP2280-2): Deliberately slows VOUT ramp to suppress inrush current in capacitive loads (e.g., USB peripherals, display modules). |
| Quiescent Current | 0.004 µA typical: Reduces standby power draw in always-on subsystems (e.g., Bluetooth headset audio path, GPS backup power). |
| Output Discharge Resistance | 20–40 Ω (RDISCH): Provides rapid, controlled discharge of output capacitance (<1 ms for 100 µF) when disabled, preventing floating voltage hazards. |
| Enable Logic Threshold | VIH = 1.4V min (VIN ≤ 2.7V): Ensures reliable activation from 1.8V GPIOs without external pull-ups or translators. |
| Thermal Resistance θJA | 160 °C/W (SOT25): Requires minimal PCB copper area for thermal management in space-constrained handheld designs. |
Pinout & Package
AP2280-2WG-7 is housed in a RoHS-compliant, lead-free SOT25 (SC-74A) surface-mount package with 5 pins, optimized for compact portable layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DIS (Pin 1) | Active discharge control | When externally connected to OUT, enables fast discharge path through internal FET; left open if discharge not required. |
| GND (Pin 2) | Power ground reference | Primary return path for IN, OUT, and internal bias circuits; must be low-impedance connection to system ground plane. |
| OUT (Pin 3) | Switched output node | Drain of internal P-MOSFET; connects to load; requires 0.1 µF local ceramic bypass to GND for transient stability. |
| IN (Pin 4) | Input power rail | Source of internal P-MOSFET; connects to main supply; requires 1 µF ceramic decoupling capacitor close to pin. |
| EN (Pin 5) | Logic-enable input | Active-high digital control; drives internal gate driver; threshold scales with VIN for wide supply compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| Slew-rate-controlled turn-on | Fixed 1ms rise time (AP2280-2) eliminates need for external RC networks while guaranteeing repeatable inrush suppression. |
| Ultra-low quiescent current | 0.004 µA enables >10-year battery life in always-connected standby circuits (e.g., real-time clock backup domains). |
| Dedicated discharge pin (DIS) | Internal 20–40 Ω discharge FET allows safe, rapid output collapse without external MOSFET or resistor network. |
| Wide-input logic-compatible EN | VIH adapts from 1.4V to 1.7V across 1.5–6V VIN range, ensuring direct interface with 1.8V/2.5V/3.3V/5V microcontrollers. |
| Green packaging | SOT25 package uses halogen-free molding compound (no Br/Sb), meeting IPC-1752 and RoHS Directive 2002/95/EC. |

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 |
|---|---|---|---|
| TCK107AG,314 (Toshiba) | 0.9ms typical rise time; 65mΩ RDS(ON) @ 5V; no DIS pin; SOT-25 package. | Lacks active output discharge; requires external circuitry for fast VOUT collapse. | Select when lowest RDS(ON) is critical and discharge is handled elsewhere in design. |
| MCP1643-I/MS (Microchip) | Integrated boost converter + load switch; 1.8–5.5V input; 300mΩ RDS(ON); no slew control. | Provides regulated output voltage; not a direct replacement for unregulated high-side switching. | Select only when voltage boosting is required alongside load switching - not a functional substitute. |
Compared with TCK107AG,314 and MCP1643-I/MS, AP2280-2WG-7 uniquely combines guaranteed 1ms slew control, integrated DIS functionality, and sub-µA quiescent current in a cost-optimized SOT25 footprint - making it optimal for inrush-sensitive, battery-critical portable subsystems where simplicity and reliability are prioritized over voltage regulation or ultra-low RDS(ON).

FAQ
What is the function of the DIS pin on AP2280-2WG-7?
The DIS (discharge) pin provides a dedicated path to actively pull the OUT node to GND when the device is disabled. When externally connected to OUT, it engages an internal 20–40 Ω discharge FET, collapsing output voltage within milliseconds - critical for preventing floating voltages in downstream circuits like ADC references or I²C pull-ups. Leaving DIS unconnected disables this feature.
Can AP2280-2WG-7 operate from a 1.5V supply?
Yes - AP2280-2WG-7 is fully specified down to 1.5V input, with verified operation across the full 1.5–6.0V range. At 1.5V, RDS(ON) rises to 200–250 mΩ and EN logic thresholds scale accordingly (VIH = 1.4V min), enabling use in legacy 1.8V logic domains and emerging ultra-low-voltage IoT subsystems without level translation.
How does the 1ms slew rate affect maximum load capacitance?
The 1ms turn-on rise time (TON) is characterized with a 10 Ω resistive load but scales predictably with capacitive loads: for a 100 µF output capacitor, VOUT reaches 90% of VIN in ~1.1ms under typical conditions. This ensures inrush current stays below 100 mA even for 220 µF loads, simplifying compliance with USB and MHL power budget requirements.
Is AP2280-2WG-7 pin-compatible with AP2280-1WG-7?
Yes - both share identical SOT25 pinout, electrical interface, and package dimensions. The sole functional difference is slew rate: AP2280-1WG-7 has 100 µs rise time, while AP2280-2WG-7 provides 1ms. No layout or firmware changes are needed when swapping between them; selection depends solely on required inrush suppression level.
