Hitachi Develops High-voltage Motor Driver ICs Primarily for RACs

Hitachi Power Semiconductor Device (HPSD) has developed two high-voltage motor driver integrated circuits (ICs) primarily for room air conditioners (RACs). The single-chip IC products ECN30216 and ECN30624 are able to tolerate large variations in supply voltage. Both products possess the function of shutting down all the output devices when overvoltage is detected in the motor drive state and thereby achieves the withstanding voltage of 1,000V. ECN30216 is mainly for the fan-motors used for indoor units of air conditioners, and ECN30624 is principally for those of outdoor units. Shipping of the products began in June 2022.
