Overview
The AP2191MPG-13 is a high-side power distribution switch manufactured by Diodes Incorporated. It features a single output capable of delivering 1.5 A continuous current with a maximum on-resistance of 115 mOhms. The device operates within a supply voltage range of 2.7 V to 5.5 V and includes an integrated current limit of 2.1 A. It utilizes an MSOP-8 EP surface-mount package and supports an interface operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates fixed current limiting protection to safeguard downstream loads against overcurrent conditions.
- Provides reverse current blocking capability to prevent backflow through the switch channel.
- Includes under-voltage lockout (UVLO) functionality to ensure stable operation during low supply voltages.
Applications
- USB port power switching and distribution
- Peripheral power management in consumer electronics
- Battery-powered device load control
Procurement Notes
Verify the specific suffix PG-13 corresponds to the required tape and reel packaging configuration for automated assembly processes. Confirm that the MSOP-8 EP package dimensions align with the target PCB footprint and thermal requirements. Ensure the component meets RoHS compliance standards applicable to the final product deployment region.
Selection Notes
Select this component when a single-channel high-side switch with 1.5 A capacity is required. Consider the 115 mOhms on-resistance for efficiency calculations. Evaluate the 2.1 A current limit threshold against potential fault scenarios. Compare the MSOP-8 EP package size against available board space constraints relative to other series variants.
Part Context
This part belongs to the AP2191 series of USB power switches. It shares functional similarities with other members like the AP2161MPG-13 but differs in current rating specifications. The series is designed for compact power distribution applications requiring integrated protection features in small outline packages.
Replacement Considerations
AP2191DSG-13 offers identical electrical performance in a DFN package format. AP2191SG-13 provides the same specifications in an SOP-8 package. Verify pin compatibility and thermal pad requirements before substituting these physical package variants.
