OREANDA-NEWS. Mitsubishi Electric Corporation (TOKYO: 6503) announced today it has developed a high-voltage integrated circuit (HVIC) to drive power semiconductors equipped with AC400 V inverter systems for use in Europe and elsewhere.

The M81748FP boasts an industry-leading 1,200 V rating and desaturation detection. Sales begin on March 31.

In particular, AC 400V inverter systems prevalent in Europe and certain other markets require high-voltage HVICs, so Mitsubishi Electric will now meet this demand with its new, high-reliability 1,200V HVIC, which boasts desaturation detection embedded with 1,200V P-channel MOSFET. Desaturation detection prevents thermal destruction of power semiconductors due to overcurrent. Fault protection using desaturation detection is more suitable for power modules from 150A than using a shunt resistor.
