The STMicroelectronics STEF12S series 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. Undervoltage lockout prevents the load from malfunction, keeping the device off if the rail voltage is too low.
