STEF01 is an 8-48V 4A programmable electronic fuse from STMicroelectronics. When connected in series to the main power rail, it protects the load against over-current and over-voltage. Voltage is clamped to a user-defined maximum, preset with external resistors. Excessive current is restricted to the programmed safe limit by controlling the internal power mosfet, and folds-back ...
