Overview
The AP2161WG-7 is a high-side power switch IC from Diodes Incorporated, designed for power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1 A with a maximum current limit of 1.5 A. The device features a maximum on-resistance of 115 mΩ, ensuring efficient power delivery. It includes protection mechanisms such as over-current limiting and thermal shutdown. The component is housed in a surface-mount SOT-25 package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- High-side switching topology for single-channel power distribution
- Integrated over-current and thermal protection for circuit safety
- Low on-resistance design to minimize power loss during operation
Applications
- USB port power switching and distribution
- Peripheral device power management
- General-purpose load switching in consumer electronics
Procurement Notes
Verify the specific suffix 'WG-7' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the required operating voltage and current ratings align with the system design specifications before integration. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.
Selection Notes
Select this component when a single-channel high-side switch with 1 A continuous current capability is required. It is suitable for applications needing low on-resistance and integrated fault protection within a compact SOT-25 footprint. Consider alternative packages if higher current or multi-channel support is needed.
Part Context
This part belongs to the AP2161 series of power switches from Diodes Incorporated. The series offers various packaging options and current ratings to suit different power distribution needs. The WG-7 variant specifically denotes the SOT-25 surface-mount package configuration.
Replacement Considerations
Check for direct substitutes within the same series, such as AP2161MPG-13, which shares similar electrical characteristics but uses an MSOP-8 EP package. Verify pin-to-pin compatibility and parameter alignment before substitution.
