Overview
The AP2151AS-13 is a single-channel high-side power switch IC from Diodes Incorporated, designed for USB and hot-swap applications. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in an SOIC-8 package. The device features a maximum on-resistance of 11 mOhm and supports an output current of 0.8 A with a controlled rise time of 0.6 ms.
Feature Summary
- Integrated current limiting and thermal protection for short circuit safety
- Controlled rise time to minimize inrush current during activation
- Built-in undervoltage lockout functionality for stable operation
- Open-drain flag output with deglitch capability for fault indication
Applications
- USB port power distribution and switching
- Hot-swap peripheral connection circuits
- Battery-powered device power management
- Overcurrent protection for low-voltage loads
Procurement Notes
Verify the specific suffix AS-13 against the manufacturer datasheet to confirm the SOIC-8 package and pin configuration. Ensure compatibility with system voltage requirements between 2.7 V and 5.5 V. Confirm RoHS compliance status through official documentation before integration into regulated products.
Selection Notes
Select this component when a single-channel high-side switch with low on-resistance is required for USB applications. Consider the SOIC-8 package for standard surface-mount assembly. Evaluate the 0.8 A current limit against load requirements to ensure adequate headroom for peak currents without triggering unnecessary shutdowns.
Part Context
This part belongs to the AP2151 series of integrated power switches optimized for Universal Serial Bus (USB) compliance. The series offers various packages including MSOP-8EP and U-DFN2018, providing flexibility for different board space constraints while maintaining consistent electrical performance characteristics across the family.
Replacement Considerations
Cross-reference with other AP2151 variants such as AP2151SG-13 or AP2151AMP-13 if package changes are acceptable. Verify that substitute parts maintain the same 2.7 V to 5.5 V operating range and 0.8 A current limit specifications.
