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
