AP1212HSL-13

Overview

The AP1212HSL-13 is a dual integrated high-side power switch manufactured by Diodes Incorporated, designed for Universal Serial Bus (USB) applications. It features two independent switches with active-low enable inputs and open-drain fault flag outputs. 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. It operates within a temperature range of -40°C to +125°C and is housed in an SOP-8 package.

Feature Summary

• Dual independent high-side switches optimized for USB downstream ports
• Active-low enable control with independent open-drain fault flags
• Integrated thermal shutdown and under-voltage lockout protection
• Soft-start functionality to prevent upstream voltage drops during hot-plugging

Applications

• USB hub circuits
• Hot-plug-in power supplies
• Battery-charger circuits

Procurement Notes

Verify the specific suffix 'L' indicates active-low enable logic, distinct from the 'H' variant. Confirm availability status as this series may be discontinued or restricted. Ensure the SOP-8 package matches the target PCB footprint. Check RoHS compliance documentation for lead-free finish requirements before finalizing procurement.

Selection Notes

Select this component when dual-channel USB power distribution is required with low quiescent current. The active-low enable configuration suits systems where logic signals are inverted. Verify that the 1.25A short-circuit limit meets safety standards for the specific application. Consider the SOP-8 package size constraints relative to available board space.

Part Context

This part belongs to the AP1212 series of dual USB high-side power switches. It shares core architecture with variants like the AP1212HSG-13, differing primarily in enable logic polarity. The series is engineered for self-powered and bus-powered USB environments, offering compact integration compared to discrete MOSFET solutions.
