Overview
The AP2171SG-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 A with a fixed current limit of 1.5 A. The device features a maximum on-resistance of 115 mOhms, ensuring efficient power delivery. It includes fault protection mechanisms such as overcurrent limiting, thermal shutdown, reverse current blocking, and under-voltage lockout. The component is housed in an SOP-8 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates comprehensive fault protection including fixed current limiting, thermal shutdown, reverse current blocking, and under-voltage lockout for robust circuit management.
- Features a low on-resistance design to minimize conduction losses and improve overall power efficiency during operation.
- Provides active load discharge functionality to rapidly dissipate stored energy when the switch is turned off.
Applications
- USB port power switching and distribution
- Peripheral device power control
- Battery-powered equipment load drivers
Procurement Notes
Verify the specific suffix SG-13 against official Diodes Incorporated documentation to confirm the SOP-8 package configuration. Ensure compatibility with required PCB footprint dimensions and thermal relief patterns. Confirm that the selected variant meets all necessary environmental compliance standards for the intended deployment region.
Selection Notes
Select this component for applications requiring single-channel high-side switching with integrated protection features. Consider the 1 A current rating and 115 mOhm on-resistance for appropriate load matching. Evaluate the SOP-8 package constraints against available board space and thermal dissipation requirements before finalizing the design.
Part Context
