Packaging form
The speed control circuit of a DC brush motor changes the output of the VMOS transistor connected to it through an external resistance network, achieving the function of controlling the speed of electric tools.
4V ~ 20V
3.5mA ~ 5mA
3.5kHz~4.5kHz;
0~80%
SOP8
The output end of the DC brushless motor speed control circuit is equipped with a 14V clamp structure. By bridging the internal resistance network, the PWM duty cycle output can be changed to control the motor speed.
7V ~ 24V
7mA ~ 10mA
2.5kHz~3.5kHz; 5.5kHz~6.5kHz
0~75%
