Description
General part information
STEF01 Series
The STEF01 is a universal integrated electronic fuse optimized for monitoring output current and the input voltage on DC power lines.
When connected in series to the main power rail, it is able to 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.
The device is fully programmable. UVLO, overvoltage clamp and start-up time can be set by means of external components.
