General Description

ET9552 can disconnect the systems from its output pin(OUT) in case wrong input operating conditions are detected. The system is positive over-voltage protected up to 28V. The internal over-voltage threshold(OVLO) is 10.5V. ET9552 has internal Thermal-Shutdown Protection and Input Voltage detection. The device is packaged in advanced full-Green compliant WLCSP-12 1.55mm×1.1mm package.
