Overview
The AP2142AFGEG-7 is a dual-channel current-limited high-side power switch designed for USB and hot-swap applications. It features an active-low enable input, 0.5A output current capability, and 0.7A accurate current limiting. The device includes built-in soft-start with a typical rise time of 0.6ms and fast short-circuit response of 2µs. Operating voltage ranges from 2.7V to 5.5V with an on-resistance of 85mΩ. Protection mechanisms include thermal shutdown, reverse current blocking, and UVLO. A fault flag (FLG) provides status reporting with 7ms blanking time. ESD protection meets 2kV HBM and 300V MM standards. It operates within -40°C to +85°C ambient temperature.

Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm RoHS compliance and lead-free status upon receipt. Check datasheet revisions for any parameter updates. Ensure storage conditions maintain moisture sensitivity level integrity. Validate package marking against official specifications to prevent counterfeit substitution.
Selection Notes
Select this component for dual-port USB power distribution requiring active-low control logic. Suitable for systems needing precise current limiting at 0.7A with 0.5A continuous output. Ideal for space-constrained designs utilizing DFN3030E-8 packages. Consider thermal management requirements given the exposed pad configuration. Verify enable signal polarity matches system design before integration.
Part Context
Part of the AP2142/2152 family of dual-channel power switches optimized for Universal Serial Bus interfaces. Manufactured by Diodes Incorporated using green molding compound free of bromine and antimony. Complies with IEC60950-1 CB scheme certification and UL recognition file E322375. Available in multiple package options including SO-8, MSOP-8EP, and DFN3030E-8 variants.
Replacement Considerations
AP2152AFGEG-7 offers identical electrical characteristics but utilizes active-high enable logic instead of active-low. Verify interface compatibility when substituting due to inverted control signal requirements. Other family members may differ in current ratings or package types.
