Overview
The AP2191FMG-7 is a single-channel high-side power switch manufactured by Diodes Incorporated. It features a P-channel output configured for USB switching applications with a maximum continuous output current of 1.5A. The device operates within a load voltage range of 2.7V to 5.5V and utilizes an active-low enable interface. Key electrical characteristics include a typical on-resistance of 90 milliohms and a fixed current limit protection mechanism. The component is housed in a compact 6-UFDFN package with dimensions of 2.0mm x 1.8mm, designated as 6-DFN2018, and supports surface mount installation.
Feature Summary
- Integrated fault protection including fixed current limiting, overtemperature shutdown, reverse current blocking, and under-voltage lockout.
Applications
- USB port power distribution
- High-side load switching
- Power management in portable electronics
Procurement Notes
Verify the specific ordering suffix to confirm the exact packaging configuration, such as tape and reel specifications, prior to procurement. Ensure that the selected variant matches the required thermal performance and pinout compatibility for the target PCB layout. Confirm RoHS compliance status through official manufacturer documentation to meet regulatory requirements for the intended market.
Selection Notes
Select this component when a single-channel high-side switch with 1.5A capacity and low on-resistance is required. Consider the 90 milliohm typical resistance for efficiency optimization. Evaluate the integrated protection features against system safety requirements. Verify that the operating temperature range of -40°C to 85°C aligns with environmental conditions.
Part Context
This part belongs to the AP2191 series of USB power switches from Diodes Incorporated. The family includes variants with different packages and electrical tolerances. The FMG suffix typically denotes a specific tape and reel packaging option within the DFN2018 form factor. This series is designed for efficient power distribution in consumer and industrial electronic devices.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source data. Cross-reference with other single-channel high-side switches only if electrical parameters and pinout compatibility are verified through official datasheets.
