Overview
The AP2161DFMG-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 1 A with a fixed current limit of 1.5 A. The device features a maximum on-resistance of 110 mOhms, ensuring efficient power delivery. Switching characteristics include a maximum turn-on time of 50 us and a maximum turn-off time of 50 us. It is housed in a UDFN-6 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates a single high-side P-channel switch optimized for USB 2.0 power distribution applications.
- Includes built-in fault protection mechanisms such as fixed current limiting and thermal shutdown.
- Features fast switching times with defined turn-on and turn-off delays for precise control.
Applications
- USB hub power switching
- Portable device power management
- Peripheral power distribution
Procurement Notes
Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm that the UDFN-6 package variant matches the design requirements. Check RoHS compliance status through official documentation. Ensure the manufacturer source is authorized to guarantee component authenticity. Review the datasheet for specific handling and storage conditions relevant to the moisture sensitivity level.
Selection Notes
Select this component when a single-channel solution with 1 A continuous current capability is required. The low on-resistance makes it suitable for applications prioritizing efficiency over multiple channels. Consider the UDFN-6 footprint constraints during PCB layout. Evaluate the 50 us switching speed against system timing requirements. Verify compatibility with the 2.7 V to 5.5 V input voltage range of the host system.
Part Context
This part belongs to the AP2171 series of USB power switches from Diodes Incorporated. It shares functional similarities with other single-channel devices in the lineup but differs in package type and specific electrical tolerances. The series targets compact consumer electronics requiring reliable power gating. It complements multi-channel variants by offering a simplified solution for single-load applications.
FAQ
What is the maximum turn-off time for the AP2161DFMG-7?
The maximum turn-off time is specified as 50 us in the official product specifications.
Does the AP2161DFMG-7 include reverse current protection?
Official documentation for this specific part number does not explicitly list reverse current protection as a standard feature; users should consult the full datasheet for detailed fault protection configurations.
