Overview
The AP2181FMG-7 is a high-side power switch IC from Diodes Incorporated, designed for power distribution applications. It features a single output capable of delivering up to 1.5A with a maximum on-resistance of 110mΩ and a current limit of 2.1A. The device operates within a supply voltage range of 2.7V to 5.5V. Key timing parameters include a maximum turn-on time of 50μs and a maximum idle time of 10μs. It functions reliably across an operating temperature range from -40°C to +85°C and is housed in a compact SMD/SMT package.
Feature Summary
- Integrates active low enable control for precise load management
- Includes built-in fault protection mechanisms such as overcurrent limiting and thermal shutdown
- Provides fast switching response with defined turn-on and idle times
Applications
- USB port power switching and distribution
- Peripheral device power control in consumer electronics
- Battery-powered equipment load switching
Procurement Notes
Verify the specific suffix FMG-7 against the manufacturer datasheet to confirm the exact package type and tape-and-reel quantity. Ensure the ordering information matches the required RoHS compliance status and lead times provided by authorized distributors. Cross-reference the Mouser number 621-ap2181fmg-7 for accurate sourcing details.
Selection Notes
Select this component when a single-channel high-side switch with 1.5A continuous current capability is required. It is suitable for systems operating between 2.7V and 5.5V where active-low control logic is preferred. Consider the 110mΩ on-resistance for efficiency calculations and ensure the application environment stays within the specified -40°C to +85°C temperature range.
Part Context
This part belongs to the AP2181 series of USB power switches manufactured by Diodes Incorporated. It is functionally similar to the AP2181SG-13 but differs in packaging, utilizing a DFN format instead of SOP-8. The series is designed for portable electronics requiring efficient power distribution and robust fault protection.
Replacement Considerations
The AP2181SG-13 serves as a pin-compatible alternative with identical electrical specifications but utilizes an SOP-8 package instead of the DFN configuration.
