AP2171MPG-13

Overview

The AP2171MPG-13 is a single-channel high-side power switch IC designed for USB 2.0 power distribution 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 a maximum on-resistance of 115 mOhms, ensuring efficient power delivery. It includes comprehensive protection mechanisms such as over-temperature shutdown, under-voltage lockout, reverse current blocking, and short-circuit protection. The component is housed in an MSOP-8 EP surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

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 hub power switching
• Peripheral port power distribution
• Battery-powered device power management

Procurement Notes

Verify the specific suffix 'MPG-13' against the manufacturer's official datasheet to confirm the MSOP-8 EP package type and tape-and-reel orientation. Ensure that the ordering information matches the exact part number designation to avoid confusion with other package variants like SG or DWG within the same AP2171 series. Cross-reference the RoHS compliance status and moisture sensitivity level requirements prior to procurement.

Selection Notes

Select this component when a single-channel solution with 1 A continuous current capability is required for USB-compliant power routing. The low on-resistance minimizes power loss compared to discrete MOSFET solutions. Consider the MSOP-8 EP package for improved thermal dissipation in space-constrained designs. Evaluate the need for integrated reverse current protection if the application involves hot-plugging scenarios or bidirectional power flow risks.

Part Context

The AP2171MPG-13 belongs to the AP2171 family of USB power switches from Diodes Incorporated. This series is engineered to replace discrete FET-based power switches, offering a compact footprint and simplified design implementation. The family provides various package options including SOP-8, SOT-25, and UDFN-6, catering to different board space and thermal requirements while maintaining consistent electrical performance characteristics.
