Overview
The AP2181SG-13 is a high-side power distribution switch manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 5.5 V and supports a continuous output current of 1.5 A with a current limit of 2.1 A. The device features a maximum on-resistance of 115 mOhms, a maximum turn-on time of 50 us, and a maximum turn-off time of 10 us. It is housed in an SOP-8 surface-mount package and functions across a temperature range of -40 C to +85 C.
Feature Summary
- Single-channel high-side power switching capability for USB applications
- Integrated current limiting protection at 2.1 A
- Low on-resistance for efficient power distribution
Applications
- USB power distribution circuits
- Peripheral power management
- Load switching in portable devices
Procurement Notes
Verify the specific suffix SG-13 corresponds to the SOP-8 package configuration. Confirm RoHS compliance status through official documentation. Ensure the ordering quantity aligns with the manufacturer's standard reel packaging requirements. Cross-reference the datasheet revision date to validate parameter accuracy before integration.
Selection Notes
Select this component when a single-channel high-side switch with 1.5 A capacity is required. The SOP-8 package suits designs needing standard surface-mount footprints. Verify that the 2.7 V minimum operating voltage meets system logic levels. Consider the 115 mOhm on-resistance for thermal management calculations in dense layouts.
Part Context
This part belongs to the AP2181 series of USB power switches from Diodes Incorporated. It shares core electrical specifications with other variants like AP2181WG-7 but differs in physical packaging. The SOP-8 form factor provides distinct pinout and thermal characteristics compared to SOT-25 or UDFN options within the same functional family.
Replacement Considerations
AP2181WG-7 offers identical electrical performance in a SOT-25 package. AP2181DFMG-7 provides similar specs in a UDFN-6 footprint. Substitution requires verifying package compatibility and pinout alignment with the existing PCB layout.
