ET3206N
Description
The ET3206N is a three-phase sensorless brushless DC motor driver IC designed for low noise and low voltage applications.It drives the motor sinusoidally, giving low noise performance. The ET3206N has useful functions such as start-up circuit, Pulse Width Modulation (PWM) speed control, RD\FG output for different control applications, as well as protective features such as lock and thermal protection. ET3206N is best suited for silent applications such as game consoles or CPU fans. It is available in DFN3x3- 10 package.
Protection functions of ET3206N are comprehensive, including lock protection and automatic recovery, thermal shutdown. These prevent the control circuits and the motor from being damaged, particularly under stressed applications and demanding environments.
