Overview
The AP2171DM8G-13 is a high-side power switch IC from Diodes Incorporated, designed for USB power distribution. It features two independent outputs with a continuous output current of 1.9A and a fixed current limit of 1.5A per channel. The device operates within a supply voltage range of 2.7V to 5.5V and exhibits a maximum on-resistance of 115mΩ. It includes comprehensive fault protection mechanisms such as over-temperature shutdown, reverse current blocking, and under-voltage lockout. The component is housed in an 8-pin MSOP package and supports surface mount installation.
Feature Summary
- Dual-channel high-side switching topology for independent load control
- Integrated fault protection including thermal shutdown and reverse current blocking
- Low on-resistance design for efficient power distribution
- Compatible with standard USB 2.0 power requirements
Applications
- USB hub power distribution circuits
- Portable electronic device power management
- Industrial control system I/O protection
- Consumer electronics peripheral power switching
Procurement Notes
Verify the specific suffix DM8G against official Diodes Incorporated documentation to confirm the MSOP-8 package and dual-channel configuration. Ensure compatibility with required operating temperatures and current limits for the target application. Cross-reference ordering information with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual-channel high-side switching is required within a compact MSOP footprint. It is suitable for applications needing integrated fault protection without external discrete components. Consider the 1.9A total current capacity and 115mΩ on-resistance for efficiency calculations. Verify that the 2.7V to 5.5V input range matches the system power supply.
Part Context
This part belongs to the AP2171 series of USB power switches manufactured by Diodes Incorporated. The series offers various configurations including single and dual-channel options in different packages like SOP-8, DFN, and MSOP. These devices are engineered for portable electronics and industrial applications requiring reliable power distribution and protection.
Replacement Considerations
Check Diodes Incorporated datasheets for alternative part numbers within the AP2171 family that match the dual-channel requirement and MSOP-8 package. Verify pin-to-pin compatibility and electrical specifications before substitution.
