产品概述
描述
The STEF05S is an integrated electronic fuse optimized for monitoring the 5 V DC power lines.
When connected in series to the main power rail, it is able to precisely detect and react to overcurrent and overvoltage conditions.
When an overload condition occurs, the device limits the output current to a safe value defined by the user. If the anomalous overload condition persists, the device goes into an open state, disconnecting the load from the power supply.
In case of overvoltage on the input, the device regulates the output to a preset safe value.
Undervoltage lockout prevents the load from malfunction, keeping the device off if the rail voltage is too low.
The STEF05S features the adjustable turn-on slew rate, which is useful to keep the inrush current under control during startup and hot-swap operations.
The STEF12S is a companion chip for the 12 V rails, useful to implement a complete power rail control in data-storage applications.
