The SY67343 is designed for sensorless control of three-phase brushless DC (BLDC) motor, especially for low noise, low external component count and high efficiency applications. The SY67343 also integrates three half-H-bridges, which have low turn on resistance. A 180° modified SPWM is used to reduce the motor noise and torque ripple. The device can be easily configured through an I2C interface to drive different motors.
The SY67343 supplies several protections and abnormal state detections to ensure reliable operation of the motor, such as over current protection, short circuit protection, under voltage lockout, thermal shutdown and abnormal motor states protection. A low-power sleep mode is also provided.
To be compatible with industry-standard devices, the SY67343 package is 24-pin TSSOP24E.
