Brushless DC Motor Microcontroller IC , 12V DC Motor Speed Control
IC
Features:
JY02A is ASIC for sensorless brushless DC motor , with simple
peripheral circuit, perfect function, compact size, simple
debugging (almost no debugging), high drive efficiency, flexible
application, widely application, etc.
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.
