Overview
The AP2171AMP-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 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 and utilizes an MSOP-8 EP package for surface mount installation. It functions across an extended temperature range from -40°C to +85°C.
Feature Summary
- Integrates overtemperature protection and under-voltage lockout for enhanced system reliability
- Provides reverse current blocking to prevent backflow into the power source
- Includes a status flag output to indicate active fault conditions or normal operation
Applications
- USB port power switching in host controllers
- Power distribution in portable electronic devices
- Battery-powered equipment requiring load protection
Procurement Notes
Verify the specific suffix against official Diodes Incorporated documentation to confirm pinout compatibility and thermal pad requirements. Ensure the selected variant matches the required package type and operating temperature range for the target application environment.
Selection Notes
Select this component when a single-channel high-side switch with integrated fault protection is required. Consider the MSOP-8 EP package for space-constrained designs needing improved thermal dissipation compared to standard packages.
Part Context
This part belongs to the AP2171 series of USB power switches. The family includes variants with different channel counts and package options, such as dual-channel versions in SOP-8 or UDFN-6 packages, offering flexibility for various power distribution architectures.
