FEATURES

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.
