Descriptions:
JY02A DC brushless and Hallless sensor DC brushless motor dedicated control chip
JY02A drive DC brushless and Hallless motor special integrated circuit has the characteristics of simple peripheral circuit, perfect function, small size, simple debugging (almost no debugging), high driving efficiency, flexible application, and wide application.
JY02A is a pure hardware application, eliminating the trouble of engineers writing programs. Various brushless and Hallless motor drive control circuits are solidified in JY02A, such as adaptive starting circuit, power compensation circuit, Q value correction circuit, power factor correction, Phase detection circuit, two-way operation decoding circuit, locked rotor protection circuit, back electromotive force detection circuit, current detection & control circuit, voltage detection & protection circuit, etc., after a very small amount of peripheral component adjustment, it can drive various DC power circuits well. Brushless Hall motor, JY02A has a certain load starting ability, which is very important in most applications. JY02A can be applied to three-phase brushless DC motors with "Y" and "delta" connections
Application areas:
sweeping robots, automobile water pumps, wall-mounted boiler circulating pumps, household booster pumps, oxygen generators, various fans/blowers, electric screwdrivers, electric curtains, automatic doors, hydraulic oil pumps, high-pressure air pumps, new energy automobile air-conditioning compressors , Refrigerator DC brushless compressors, AGV trolleys, various linear and circular logistics sorting equipment, lawn mowers, sprayers, underwater propellers, etc.
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
