Overview
The AP1212LSL-13 is a dual integrated high-side power switch optimized for USB applications. It features independent enable and flag functions with an active-low control logic. The device supports input voltages from 2.7V to 5.5V, providing up to 500mA continuous current per port with a typical on-resistance of 110mΩ. Fault current is limited to 1.25A maximum, while supply current drops to 1μA in the off-state. It includes thermal shutdown, under-voltage lockout, and soft-start capabilities within an 8-pin SOP package.
Feature Summary
- Dual independent high-side switches with active-low enable control
- Integrated open-drain fault flag output for status indication
- Soft-start functionality minimizes upstream voltage drop during activation
Applications
- USB hub circuits
- Hot plug-in power supplies
- Battery-charger circuits
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated distributors or verified channels. Confirm RoHS compliance and package integrity upon receipt. Check datasheet revisions for specific electrical tolerances. Ensure storage conditions meet humidity sensitivity requirements prior to assembly.
Selection Notes
Select this model when active-low enable signals are required for USB power distribution. The dual-channel design suits applications needing independent port control. Verify that the 1.25A short-circuit limit aligns with downstream safety standards. Consider the 8-pin SOP footprint for PCB layout constraints.
Part Context
This component belongs to the AP1212 series of dual USB power switches. It shares functional similarities with the AP1212LSG variant but differs in enable logic polarity. The series is designed to meet USB specifications for self-powered and bus-powered devices, offering low on-resistance and comprehensive protection features.
Replacement Considerations
The AP1212LSG-13 serves as a direct substitute, differing only in enable logic (active-high versus active-low). Ensure circuit compatibility with the alternative enable signal polarity before swapping components.
