ST's low-resistance power switches offer reliable overcurrent and thermal protection. They are designed for general-purpose power protection or for applications such as USB, hot-swap and power distribution.
The power switches come in 1- or 2-channel versions with fixed and adjustable overcurrent limit. Some include a USB charge controller specifically designed to optimize USB host applications.
