ET9918B


General Description
ET9918B can disconnect the systems from its output pin(OUT) in case wrong input operating conditions are detected. It achieve wide input voltage range from 2.5V to 29V and reverse blocking voltage up to 24V. The inside reverse blocking FET prevents the leakage current from output side to input side when input power supply is removed. ET9918B has an internal 14.5V OUT over-voltage protect threshold voltage and thresholds can also be programmed by outside OVLO pin. High accuracy current indicator is set internally. Default 7.5A over current protection is also set inside. Enable control is available to cut off the energy path. ET9918B has internal Thermal-Shutdown Protection.
