Overview
The AP1212HSL-U is a dual USB high-side power switch manufactured by Diodes Incorporated. It features two independent switches with active-high enable inputs, optimized for self-powered and bus-powered Universal Serial Bus applications. The device supports an input voltage range of 2.7V to 5.5V and provides a minimum continuous current of 500mA per port. Key electrical characteristics include a typical on-resistance of 110mΩ, a maximum short-circuit current limit of 1.25A, and a typical on-state supply current of 110μA. The component operates within a temperature range of -40°C to +125°C and utilizes an SOP-8L package.
Feature Summary
- Dual independent high-side switches with active-high enable control
- Compliant with USB specifications for reliable power distribution
- Integrated thermal shutdown protection for enhanced safety
- Independent open-drain fault flag pins for status monitoring
Applications
- Self-powered Universal Serial Bus (USB) systems
- Bus-powered Universal Serial Bus (USB) devices
- Power distribution circuits requiring independent channel control
Procurement Notes
Verify the specific suffix 'U' against the manufacturer's official documentation to confirm exact pinout, lead finish, or environmental compliance variations compared to standard variants. Confirm availability status as this series may be subject to discontinuation notices; consult recent Product Change Notifications (PCN) or End-of-Life (EOL) alerts from Diodes Incorporated prior to finalizing procurement plans.
Selection Notes
Select this component when designing USB power interfaces requiring independent channel management with active-high logic control. Ensure the design accommodates the 110mΩ typical on-resistance for expected voltage drop calculations. Verify that the application environment stays within the specified -40°C to +125°C operating temperature range and that the 1.25A short-circuit limit aligns with downstream load protection requirements.
Part Context
This part belongs to the AP1212 series of dual integrated high-side power switches. The series is specifically engineered for USB applications, offering features such as soft-start functionality and low standby currents. The 'HSL' designation typically indicates active-high enable logic and specific packaging options within the broader AP1212 family managed by Diodes Incorporated.
Replacement Considerations
Diodes Incorporated datasheets explicitly recommend using the AP2146 or AP2156 as replacements for the AP1212 series in new designs due to product lifecycle status. Verify functional compatibility regarding enable logic and current limits before substituting.
