产品概述

描述

The STEF12S is an integrated electronic fuse optimized to monitor the 12 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 STEF12S features the adjustable turn-on slew-rate, which is useful to keep the in-rush current under control during startup and hot-swap operations.
On the DFN10 package a dedicated pin provides a gate control for an external optional N-channel Power FET, used to implement the reverse current blocking in case of input voltage loss.
The STEF05S is a companion chip for the 5 V rails, useful to implement a complete power rail control in data-storage applications.
