The SI4848DY-T1-E3 is an integrated circuit (IC) manufactured by Vishay. It is an integrated circuit designed to provide high-speed switching and voltage-level shifting. It features an active-low enable and a buffered output that supports direct high-side switching for efficient control of loads. The IC operates over a wide voltage range, from 4V up to 28V, and can withstand up to 40V of maximum supply voltage. The SI4848DY-T1-E3 is built using flash EEPROM technology that ensures programmable output voltage levels for dynamic range shifting. It also includes protection features such as over-voltage and over-temperature lock protection for safe operation.
