Overview
The AP22804AW5-7 is a high-side power switch IC from Diodes Incorporated, designed for load distribution applications. It operates within an input voltage range of 2.7V to 5.5V and supports a continuous output current of 2.5A with a maximum current limit of 3A. The device features a typical on-resistance (RDS(ON)) of 65mΩ. Key electrical parameters include a maximum turn-on time of 1.7ms and a maximum discharge time of 20µs. It functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrated high-side N-channel MOSFET for efficient power distribution
- Built-in fault protection including overcurrent, short circuit, and thermal shutdown
- Configurable enable input polarity options for system flexibility
- Integrated output discharge capability for controlled voltage ramp-down
Applications
- Power distribution in portable consumer electronics
- Load switching for USB hubs and peripheral interfaces
- Battery-powered device power management systems
- Telecommunications equipment signal routing
Procurement Notes
Verify the specific suffix 'AW5-7' against the manufacturer's official datasheet to confirm pinout compatibility and package type. Ensure the selected variant matches the required enable logic polarity for the target design. Cross-reference RoHS compliance status and lead times directly with authorized distributors prior to ordering.
Selection Notes
Select this component when a compact high-side switch with integrated protection is required for 3.3V or 5V rails. The 65mΩ on-resistance balances conduction losses with cost efficiency. Consider the SOT-25 package constraints for thermal performance in high-current scenarios. Verify that the 2.5A continuous current rating exceeds the peak load requirements of the application.
Part Context
This part belongs to the AP228xx series of single-channel load switches from Diodes Incorporated. These devices are engineered for general-purpose power switching in space-constrained environments. The series offers various current ratings and package options to suit different power distribution needs in modern electronic systems.
Replacement Considerations
Check for direct substitutes within the AP228xx family that share identical pinouts and electrical characteristics. Verify equivalent RDS(ON) and current handling capabilities before substitution. Consult official cross-reference lists for validated alternatives.
