AP1212HSG-13

Overview

The AP1212HSG-13 is a dual integrated high-side power switch manufactured by Diodes Incorporated, designed for Universal Serial Bus (USB) applications. It supports an input voltage range of 2.7V to 5.5V and provides independent control for two ports. The device features a typical on-resistance of 110mΩ and a minimum continuous current of 500mA per port, with a maximum short-circuit current limit of 1.25A. It operates within a temperature range of -40°C to +125°C and is housed in an SOP-8L package.

Feature Summary

• Compliant with USB specifications for self-powered and bus-powered applications
• Features independent open-drain fault flag pins for status monitoring
• Includes thermal shutdown protection and under-voltage lockout functionality
• Supports forced output higher than input during off-state conditions

Applications

• Self-powered USB peripheral devices
• Bus-powered USB hubs and interfaces
• Portable electronic equipment requiring power distribution
• Computer peripherals and external storage drives

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm the specific suffix matches the SOP-8L package and lead-free green molding compound requirements. Check for End-of-Life notices as the datasheet indicates this part may be obsolete. Ensure RoHS compliance documentation is available for regulatory adherence in target markets.

Selection Notes

Select this component when dual-channel high-side switching with USB compliance is required. Consider the 110mΩ on-resistance for efficiency needs and the 1.25A short-circuit limit for robustness. Evaluate the SOP-8L package size against board space constraints. Verify that the 2.7V to 5.5V operating range aligns with the system's power supply architecture.

Part Context
