85mΩ high function power switch

Paul Boughton

The XC8107 power switch from Torex is optimised for USB 2.0 and 3.0 applications, as well as power line distribution and Hot plug applications. This device incorporates 85mΩ Pch MOSFET power switch for low ON resistance.

The XC8107 series includes an over-current limiting function with a high precision of ±10% and a high speed response time of 2µs and is available with fixed current limit values of 0.9A, 1.4A, 1.9A and 2.4A.

Protection circuits such as a current limiting, reverse current prevention, thermal shutdown, under-voltage lockout (UVLO) and soft start contribute to the safe operation of the application.

A flag function is provided to allow monitoring of the switch state. The flag pin is an Nch open drain output which outputs a low level during detection of over-current or over-heating, or while the reverse current prevention function is operating.

A small USP-6C package or a SOT-25 package can be selected as appropriate for the application.
