Brushless motor controller is composed of main body of the motor and drive, is a typical mechatronics product. Because of brushless motor is self-control type operation, so not as frequency control of motor speed under overloading starting of synchronous motor controller as plus startup winding on the rotor, the low static working current driver chip is explained below. The characteristics of the brushless motor controller driver chip: 1, each channel has 800 ma; 2, continuous output current capacity; 3, low saturation voltage drop; 4, TTL/CMOS compatible output level, can directly connect the CPU; 5, output, built-in clamping diodes, apply to the perceptual load; 6, control and drive integration in monolithic IC; 7, have pin high voltage protection function; 8, wide voltage range: 2. 5 v -12 v; 9, working temperature: 0 ℃ -80℃； 10, the chip has two TTL/CMOS compatible level input, has a good anti-jamming; 11, two outputs can directly drive forward and reverse motion of brushless motor controller, it has a large current driving ability, every channel can by 750 ~ 800 ma continuous current, peak current capacity can reach 1. 5 ~ 2. 0一个; 12, has lower output saturation pressure drop. Brushless motor controller built-in clamp diode reverse impact current, can release the perceptual load to make it in the drive relay, switch of stepping motor controller or power tube on the use of safe and reliable. Controller is widely used in toy car motor driver, stepper motor controller driver and switch power tube circuit, etc.
