Overview
The AP2171AW-7 is a single-channel high-side power switch IC designed for USB 2.0 applications, manufactured by Diodes Incorporated. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1 A with a fixed current limit of 1.5 A. The device features a maximum on-resistance of 115 mOhms and utilizes a SOT-25-5 surface-mount package. It includes integrated protection mechanisms such as over-temperature shutdown, reverse current blocking, and UVLO, functioning reliably across an operating temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-side P-channel MOSFET switching with built-in fault protection including over-temperature shutdown and reverse current blocking.
- Provides precise current limiting at 1.5 A to protect downstream loads from short circuits or overloads.
- Features low on-resistance for efficient power distribution in portable and USB-powered devices.
Applications
- USB 2.0 port power switching and distribution
- Portable electronic device power management
- Battery-operated equipment load switching
Procurement Notes
Verify the specific suffix AW against official Diodes Incorporated documentation to confirm package type and tape/reel specifications. Ensure compatibility with standard SMD/SMT assembly processes. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a single-channel high-side switch with 1 A continuous current capability. Consider the 115 mOhm on-resistance for thermal management requirements. Verify that the 2.7 V minimum operating voltage aligns with the system's power rail availability during low-battery conditions.
Part Context
The AP2171 series comprises single-channel USB power switches designed for compact consumer electronics. This part belongs to the AP2171 family, offering integrated protection features suitable for USB peripheral connections. It serves as a solution for managing power delivery in space-constrained mobile devices.
Replacement Considerations
AP2171DWG-7: Same electrical specifications but in SOT-25-5 package. AP2171DFMG-7: Same electrical specifications but in UDFN-6 package. AP2171FMG-7: Two-channel variant with different pinout. Verify pin compatibility and package dimensions when substituting.
