1. An isolated gate driver, comprising:
a switch connection terminal configured to have a switching element externally connected thereto;
a non-volatile memory having adjustment data written thereto;
a register configured to store the adjustment data read from the non-volatile memory;
a gate driving circuit configured to drive a gate of the switching element with a characteristic set based on a value stored in the register; and
a control logic circuit configured to keep the gate driving circuit in a disabled state until completion of reading the adjustment data from the non-volatile memory and storing the adjustment data in the register.
