Overview
The AP2151FMG-7 is a single-channel high-side power switch IC from Diodes Incorporated, designed for USB power distribution. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA with a current limit of 800 mA. The device features a maximum on-resistance of 110 mΩ and utilizes an active-high enable interface. It includes built-in protection against overcurrent, thermal overload, and undervoltage conditions. Operating temperatures span from -40°C to +85°C, and it is housed in a UDFN-6 surface-mount package.
Feature Summary
- Single-channel high-side power switching with active-high enable control
- Integrated overcurrent, thermal, and undervoltage protection mechanisms
- Low on-resistance design for efficient power distribution
- Compact UDFN-6 surface-mount packaging
Applications
- USB port power management and distribution
- Peripheral device power switching
- Portable electronic equipment power circuits
Procurement Notes
Verify the specific suffix 'FMG' corresponds to the UDFN-6 package and reel/cut tape configuration as listed. Confirm that the active-high enable logic matches the system design requirements. Ensure the operating temperature range and electrical parameters align with the target application environment before finalizing procurement.
Selection Notes
Select this component when a single-channel high-side switch with 500 mA continuous current capability is required. It is suitable for applications needing integrated protection features such as overcurrent and thermal shutdown. Consider the UDFN-6 package size and active-high enable interface compatibility during circuit design.
Part Context
This part belongs to the AP2151 series of power switch ICs from Diodes Incorporated. The series offers various current ratings and package options for USB power distribution applications. The AP2151FMG-7 specifically provides 500 mA output in a compact UDFN-6 package with active-high enable functionality.
Replacement Considerations
AP2151AW-7: Similar specifications but in SOIC-8 package. AP2151AS-13: Similar specifications but in SOIC-8 package. AP21510FM-7: Lower current rating (200 mA) in UDFN-6 package.
