Overview
The AP2141DSG-13 is a single-channel high-side power switch IC from Diodes Incorporated, designed for USB 2.0 power distribution applications. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 500 mA with a fixed current limit of 800 mA. The device features a maximum on-resistance of 115 mOhms, ensuring efficient power delivery. It includes integrated protection mechanisms such as overcurrent limiting, thermal shutdown, and under-voltage lockout (UVLO). The component is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40°C to +85°C.
Feature Summary
- Single-channel high-side switching capability optimized for USB power distribution
- Integrated fault protection including overcurrent limiting, thermal shutdown, and reverse current blocking
- Low on-resistance design for efficient power transmission
- Active-high enable interface for straightforward control logic integration
Applications
- USB port power switching and distribution
- Peripheral device power management
- Battery-powered equipment load switching
- Consumer electronics power rails
Procurement Notes
Verify the specific suffix 'DSG' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the 500 mA output current rating meets your circuit's peak load demands without triggering the 800 mA current limit during normal operation.
Selection Notes
Select this component when a single-channel solution with 500 mA capacity is required for USB or similar low-voltage applications. Consider alternative packages like DWG if lead space is constrained, or higher-current variants like AP2161 if loads exceed 500 mA. Verify that the 2.7 V minimum operating voltage aligns with your system's battery or supply characteristics.
Part Context
This part belongs to the AP2141 series of USB power switches from Diodes Incorporated. It is functionally similar to the AP2141DWG-7 but differs in packaging configuration. The series is designed for portable devices requiring reliable power management with minimal external components.
Replacement Considerations
The AP2141DWG-7 is a verified substitute offering identical electrical specifications in a different SOIC-8 variant. Ensure mechanical fitment compatibility before substitution.
