AP2191WG-7

Overview

The AP2191WG-7 is a high-side power switch IC manufactured by Diodes Incorporated, designed for USB load switch applications. It features a single P-channel output capable of handling up to 1.5A with a typical on-resistance of 90 milliohms. The device operates within a load voltage range of 2.7V to 5.5V and utilizes an On/Off interface. Integrated protection mechanisms include fixed current limiting, overtemperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). It is housed in a compact 6-UFDFN package with exposed pad, suitable for surface mount installation across an operating temperature range of -40°C to 85°C.

Feature Summary

Integrates comprehensive fault protection including fixed current limit, thermal shutdown, reverse current blocking, and under-voltage lockout.

Applications

USB port load switching
High-side power distribution

Procurement Notes

Verify the specific suffix 'WG' against the manufacturer's official documentation to confirm the exact tape and reel packaging configuration. Ensure the component meets RoHS compliance standards as indicated in the datasheet. Confirm that the 6-UFDFN footprint matches the target PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-side P-channel switch with integrated reverse current protection is required. The 90 milliohm on-resistance supports loads up to 1.5A efficiently. Consider the 6-UFDFN package size for space-constrained designs requiring robust fault protection features without external components.

Part Context

This part belongs to the AP2191 series of power switches from Diodes Incorporated. It shares functional similarities with other members like the AP2191FMG-7 but differs in physical packaging. The series is characterized by low on-resistance and integrated protection for portable electronics and USB applications.
