Automotive ET9668
General Description
ET9668 can disconnect the systems from its output pin(OUT) in case wrong input operating conditions are detected. The input voltage can be up to 28V. The internal overvoltage thresholds (OVLO) can be selected by OVLO_SEL pin. When OVLO_SEL is HIGH, the overvoltage point is 21.9V, and the overvoltage point when OVLO_SEL is grounded is 12.4V. ET9668 has internal Thermal-Shutdown Protection function.
The device is packaged in advanced full-Green compliant Wafer Level Chip Scale Packaging (WLCSP20).
