Overview
The AP2171DSG-13 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 a continuous output current of 1 A with a fixed current limit of 1.5 A. The device features an on-resistance of 95 mOhms (typical) and is housed in an 8-SOIC package. It includes integrated protection mechanisms such as over-temperature shutdown, reverse current blocking, and under-voltage lockout.
Feature Summary
- Integrates fixed current limiting and thermal shutdown for robust fault protection
- Supports reverse current blocking to prevent backflow from load to source
- Features under-voltage lockout to ensure stable operation during power transitions
Applications
- USB 2.0 port power switching and distribution
- Overcurrent protection for peripheral devices
- Hot-plug capable power management circuits
Procurement Notes
Verify the specific suffix 'SG' corresponds to the 8-SOIC package configuration required for your PCB layout. Confirm that the 1 A continuous current rating aligns with your load requirements. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications. Cross-reference the datasheet for pinout compatibility with existing designs.
Selection Notes
Select this component when a single-channel high-side switch with 1 A capacity is needed. Consider the 8-SOIC package for through-hole or standard surface-mount assembly. Evaluate the 95 mOhms typical on-resistance for efficiency needs. Compare against other AP2171 variants if different packaging like MSOP-8 or DFN-6 is preferred for space constraints.
Part Context
This part belongs to the AP2171 series of USB power switches from Diodes Incorporated. It provides a compact solution for managing power delivery to USB peripherals. The series offers various package options including SOIC, MSOP, and DFN to suit different board size limitations while maintaining consistent electrical performance characteristics across the family.
Replacement Considerations
AP2171DMPG-13: Offers identical electrical specifications but utilizes an MSOP-8 EP package instead of 8-SOIC. Verify footprint compatibility before substitution.
