ET9919B 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 26V and reverse blocking voltage up to 36V. The inside reverse blocking FET prevents the leakage current from output side to input side when input power supply is removed. ET9919B 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. ET9919B has internal Thermal-Shutdown Protection.
