JUYI Sensorless Brushless DC Motor Controller IC High Drive Efficiency With Flexible Widely Application

JUYI Sensorless Brushless DC Motor Controller IC high drive efficiency with flexible widely application

JY02A is a pure hardware application IC, which solve the trouble of writing programs. JY02A internally solidifies various sensorless

brushless DC motor drive control circuits, such as adaptive start circuit, power compensation circuit,Q value correction circuit, power

factor correction, Phase detection circuit, bidirectional operation decoding circuit,locked-rotor protection circuit, back electromotive

force detection circuit, current detection & control circuit, voltage detection & protection circuit, etc., after a very few amount of

external component adjustment, can drive various sensorless brushless DC motor, JY02A has a certain load-starting capability,

which is very important in most applications.JY02A can be applied to three-phase DC brushless motor with "Y" and "triangle"

connection.

Applications:

sweeping robots, automotive water pumps, wall-hung boiler circulation pumps, home booster pumps,oxygen generators, various

fans/blowers, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps,high pressure air pumps, automotive

air conditioning compressors , DC brushless compressor, AGV trolley, various linear and loop logistics sorting equipment, lawn

mower, sprayer, underwater propeller, etc.

Note: JY02A drive signal is positive polarity output, choosing adapted MOS drive circuit and power MOS is very important!

JY02A Drive mode and parameters:

1.UH/VH/WH phase top drive PWM output,UL/VL/WL phase bottom drive commutation signal output, this drive mode is a economic

way to reduce the costs of hardware, especially in application of high voltage and high-power motor drivers. top drive PWM output

mode is more easier circuit and higher stability than bottom drive PWM output mode.

2. The PWM frequency of JY02A is 13KHz, which not only takes into account the comprehensive ratio of efficiency and noise, but also

increases the power and reduces the power consumption of the driving circuit . The torque of the motor is higher than that of 20KHz

under the same power supply.

Pulse of JY02A

Please take a note that JY02A output one pulse signal during the BLDC motor commutating phase each time. It means JY02A not

produce one pulse when the motor turn a round. For example as following schematic diagram: its an inner rotor, 2 pairs pole motor,

it means the motor needs commutating phase for 6 times for each round, so JY02A will output 6 pulses each motor round.
