SDM03B60DBSA1 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 air purifiers. It integrates an MCU control chip, a three-phase half-bridge high-voltage gate drive circuit, and six fast-recovery power MOSFETs.
SDM03B60DBSA1 integrates various functions such as undervoltage protection and temperature output, providing excellent protection and a wide safe operating range. Since each phase has an independent negative DC terminal, the current can be detected separately.
