SDM03V70RA3 is a 3-phase brushless DC motor driver IC with highly-integrated and high reliability, using for low-power variable frequency drives such as fans and pumps. It integrates three-phase half-bridge high-voltage gate drive circuit, and six low-loss RC IGBTs.
SDM03V70RA3 integrates various protection functions such as undervoltage, short circuit, and overtemperature, providing excellent protection and a wide safe operating range. Since each phase has an independent negative DC terminal, its current can be sensed separately.
SDM03V70RA3 is designed with good insulation and perfect thermal properties. It is compact and suitable for applications requiring the compact installation.
