Automotive ET9553M
General Description
ET9553M 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 threshold (OVLO) is 10V, and also can be adjusted by external resistors. ET9553M has internal Thermal-Shutdown Protection function.
The device is packaged in advanced full-Green compliant Wafer Level Chip Scale Packaging (WLCSP12).
