Product Introduction
Sensorless 3-Phase Brushless DC Motor Driver IC: TB6633FNG/AFNG
The TB6633FNG/AFNG is a three-phase full-wave PWM driver for sensorless brushless DC (BLDC) motors. It controls motor rotation speed by changing the PWM duty cycle, based on the voltage of an analog control input.

TB6588FG: 3-Phase Full-Wave Sensorless Brushless Motor Driver
The TB6588FG incorporates the driver stage on the same chip, reducing the number of external components required and thus improving board utilization. The TB6588FG combines sensorless operation with hardware-based PWM motor control. It facilitates the use of smaller motors (without Hall sensors) and contributes to a reduction in power dissipation. The lap turn-on function for smooth phase current switching provides a quiet motor drive.
