AP2191WG-7 Description

Short technical summary and product information.

The Diodes Incorporated AP2191WG-7 is an integrated high-side power switch optimized for Universal Serial Bus (USB) and other hot-swap applications. It provides robust protection features including over-current limiting to 2.1A, thermal limiting, and under-voltage lockout (UVLO).

 

With a low on-resistance of 95mOhm typical, the AP2191WG-7 minimizes voltage drop and power dissipation. It operates over an input voltage range of 2.7V to 5.5V and features a controlled rise time of 0.6ms typical for safe power-up.

 

The device includes a fault flag output with a 7ms typical blanking time to prevent false over-current reporting. It is available in a compact SOT-25 package, suitable for surface mounting.

 

Key applications include consumer electronics, computing, and communication devices requiring reliable power management and protection for USB ports and other loads.
