Overview
The AP2171DMPG-13 is a single-channel high-side power switch IC manufactured by Diodes Incorporated. It supports a load voltage range of 2.7 V to 5.5 V and delivers 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 distribution. Switching characteristics include a maximum turn-on time and fall time of 50 µs. It operates within an ambient temperature range of -40 °C to +85 °C and is housed in a DFN6 surface-mount package.
Feature Summary
- Integrates P-channel MOSFET for high-side power switching applications
- Includes built-in fault protection mechanisms such as over-current limiting and thermal shutdown
- Provides status flag output for monitoring switch state
- Supports USB 2.0 compliant power distribution requirements
Applications
- USB port power switching and distribution
- Peripheral device power management
- Battery-powered equipment load control
- Consumer electronics power sequencing
Procurement Notes
Verify the specific suffix PG against the manufacturer datasheet to confirm pinout and package dimensions. Ensure compatibility with the target PCB footprint for the DFN6 package. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.
Selection Notes
Select this component when a single-channel high-side switch with 1 A capacity is required. Compare the 115 mOhm on-resistance against alternative packages like SOIC or MSOP if lower resistance is needed. Verify that the 50 µs switching speed meets system timing constraints.
Part Context
This part belongs to the AP2171 series of USB power switches from Diodes Incorporated. The series offers various package options including SOP-8, SOIC-8, and SOT-25-5 to accommodate different board space and thermal requirements while maintaining consistent electrical performance characteristics.
Replacement Considerations
AP2171DFMG-7 (UDFN-6 package) and AP2171SG-13 (SOP-8 package) are verified alternatives within the same series offering identical electrical specifications.
