Isolated gate driver, traction inverter, and electric vehicle

An isolated gate driver, comprising:

• a switch connection terminal configured to have a switching element externally connected thereto;
• a memory connection terminal configured to have 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;
• a fault detector configured to perform fault detection with respect to other than the non-volatile memory;
• an error detection-correction circuit configured to perform error detection and error correction with respect to the adjustment data written to the non-volatile memory;
• a first external terminal configured to externally output a result of the fault detection;
• a second external terminal configured to externally output a result of the error detection;
• and
• a fault controller configured to,
• if a one-bit error is detected in the adjustment data, bring the second external terminal into an error-indicating output state and continue with normal operation of the gate driving circuit and,
• if a two-or-more-bit error is detected in the adjustment data, forcibly stop the gate driving circuit.
